The Battle of Lens (August 20 1648) was a French victory under Louis II de Bourbon, Prince de Condé against the Spanish army under Archduke Leopold in the Thirty Years War (1618-1648). It was the last major battle of the war.Lens is a fortified city in Flanders, modern day Belgium. The city had been captured by the French in 1647. As France began to experience a rebellion of the nobility against the leadership of Cardinal Mazarin, known as the Fronde, the Spanish saw an opportunity to retake Lens and possibly gain ground. The Prince de Condé rushed from Catalonia to Flanders and an army was cobbled together from Champagne, Lorraine as well as Paris. The French army was 16,000 men (more than half were cavalry) and 18 guns. The Spanish army was larger, compromising 18,000 men (also more than half cavalry) and 38 guns. The armies drew up, but the Spanish were on high ground and Condé decided not to attack. As the French retired the Spanish cavalry skirmished with the French rear guard and the engagement escalated until the armies were fully engaged. The Spanish infantry pushed back the French, breaking the Gardes Françaises regiment, but the superior French cavalry were able to defeat their counterparts and envelop the center.

This is about the optical device. For other uses, see Lens (disambiguation).
A lens is a device for either concentrating or diverging light, usually formed from a piece of shaped glass. Analogous devices used with other types of electromagnetic radiation are also called lenses: for instance, a microwave lens can be made from paraffin wax.
In its usual form, a lens consists of a slab of glass or other optically transparent material (such as perspex) with two shaped surfaces of a particular curvature. It is the refractive index of the lens material and the curvature of the two surfaces that give a particular lens its particular properties. A lens works by refracting (bending) the light that passes through it, in a similar manner to a prism.
Lens construction
The most common type of lenses are spherical lenses, which are formed from surfaces that have spherical curvature, that is, the front and back surfaces of the lens can be imagined to be part of the surface of two spheres of given radii, R1 and R2, which are called the radius of curvature of each surface. The sign of R1 gives the shape of the front surface of the lens: if R1 is positive, the surface is convex (bulging outwards from the lens). If R1 is negative, the front surface is concave (bulging into the lens). If R1 is infinite, the surface is flat, or has zero curvature, and is said to be plane. The same is true for the back surface of the lens, except that the sign conversion is reversed: if R2 is positive, it is concave, and if R2 is negative,the back surface is convex. The line joining the centres of the spheres making up the lens surfaces is called the axis of the lens; in almost all cases the lens axis passes through the physical centre of the lens.
Lens are classified by the curvature of these two surfaces. A lens is biconvex if both surfaces are convex, likewise, a lens with two concave surfaces is biconcave. If one of the surfaces is flat, the lens is termed plano-convex or plano-concave depending on the curvature of the other surface. A lens with one convex and one concave side is termed convex-concave, and in this case if both curvatures are equal it is a meniscus lens.
If the lens is biconvex or plano-convex, a collimated or parallel beam of light passing along the lens axis and through the lens will be converged (or focused) to a spot on the axis, at a certain distance behind the lens (known as the focal length). In this case, the lens is called a positive or converging lens.
If the lens is biconcave or plano-concave, a collimated beam of light passing through the lens is diverged (spread); the lens is thus called a negative or diverging lens. The beam after passing through the lens appears to be emanating from a particular point on the axis in front of the lens; the distance from this point to the lens is also known as the focal length, although it is negative with respect to the focal length of a converging lens.
If the lens is convex-concave, whether it is converging or diverging depends on the relative curvatures of the two surfaces. If the curvatures are equal (a meniscus lens), then the beam is neither converged or diverged.
The value of the focal length f for a particular lens can be calculated from the lensmaker's equation:
where n is the refractive index of the lens material and d is the distance along the lens axis between the two surfaces (known as the thickness of the lens). If d is small compared to R1 and R2, then the thin lens assumption can be made, and f can be estimated as:
- ,
The focal length f is positive for converging lenses, negative for diverging lenses, and infinite for meniscus lenses. The value 1/f is known as the power of the lens, and so meniscus lenses are said to have zero power. Lens power is measured in dioptres, which have units of inverse meters (m-1).
- .
Lenses are also reciprocal; i.e. they have the same focal length when light travels from the front to the back as when light goes from the back to the front (although other properties of the lens, such as the aberration [see below] are not necessarily the same in both directions).
Imaging properties
As mentioned above, a positive or converging lens will focus a collimated beam travelling along the lens axis to a spot (known as the focal point) at a distance f from the lens. Conversely, a point source of light placed at the focal point will be converted into a collimated beam by the lens. These two cases are examples of image formation in lenses. In the former case, an object at an infinite distance (as represented by a collimated beam of light) is focused to an image at the focal point of the lens. In the later, an object at the focal length distance from the lens is imaged at infinity.
If the distances from the object to the lens and from the lens to the image are S1 and S2 respectively, for a lens of negligible thickness they are found by the thin lens formula:
What this means is that, if an object is placed at a distance S1 along the axis in front of a positive lens of focal length f, a screen placed at a distance S2 behind the lens will have an image of the object projected onto it, as long as S1 > f. This is the principle behind photography. The image in this case is known as a real image.
- .
Note that if S1 < f, S2 becomes negative, and the image is apparently positioned in front of the lens. Although this kind of image, known as a virtual image, cannot be projected on a screen, an observer looking through the lens will see the image in its apparent calculated position.
The magnification of the lens is given by:
where M is the magnification factor; if |M|>1, the image is larger than the object. Notice the sign convention here shows that, if M is negative, as it is for real images, the image is upside-down with respect to the object. For virtual images, M is positive and the image is upright.
- ,
In the special case that S1=∞, we have S2=f and M=-f/∞=0. This corresponds to a collimated beam being focused to a single spot at the focal point. The size of the image in this case is not actually zero, since diffraction effects place a lower limit on the size of the image (see Rayleigh criterion).
The formulas above may also be used for negative (diverging) lens by using a negative focal length (f), but for these lenses only virtual images can be formed.
Aberrations
Lenses do not form perfect images, and there is always some degree of distortion or aberration introduced by the lens which causes the image to be an imperfect replica of the object. Careful design of the lens system for a particular application ensures that the aberration is minimised.
There are several different types of aberration. Spherical aberration is caused because spherical surfaces are not the ideal shape with which to make a lens, but they are by far the simplest shape to which glass can be ground and polished and so are often used. Spherical aberration causes beams parallel to but away from the lens axis to be focused in a slightly different place than beams close to the axis. This manifests itself as a blurring of the image. Lenses in which closer-to-ideal, non-spherical surfaces are used are called aspheric lenses, which are complex to make and often extrememly expensive. Spherical aberration can be minimised by careful choice of the curvature of the surfaces for a particular application: for instance, a plano-convex lens which is used to focus a collimated beam produces a sharper focal spot when used with the convex side towards the beam.
Chromatic aberration is caused by the dispersion of the lens material, the variation of its refractive index n with the wavelength of light. Since from the formulae above f is dependent on n, if follows that different wavelengths of light will be focused to different positions. Chromatic aberration of a lens is seen as fringes of color around the image. It can be minimised by using an achromatic doublet (or achromat) in which two materials with differing dispersion are bonded together to form a single lens. This reduces the amount of chromatic aberration over a certain range of wavelengths, though it does not produce perfect correction. The use of achromats was an important step in the developement of the optical microscope.
Other kinds of aberration include coma, field curvature, barrel and pincushion distortion, and astigmatism.
Multiple lenses
Lenses may be combined to form more complex optical systems. The simplest case is when lenses are placed in contact: if the lenses of focal lengths f1 and f2 are "thin", the combined focal length F of the lenses can be calculated from:
Since 1/f is the power of a lens, it can be seen that the powers of thin lenses in contact are additive.
- .
Uses of lenses
One important use of lenses is as a prosthetic for the correction of visual impairments such as myopia and farsightedness. See corrective lens, contact lens, eyeglasses.
Another use is in imaging systems such as telescopes, microscopes, and cameras.

The lens is a component of the eye. It refracts light entering the eye and projects it onto the retina.
Light from a distant object and light from a near object being brought to a focus by changing the curvature of the lens.The lens is clear and flexible; its curvature is controlled by muscles. By changing the curvature of the lens, the eye can focus at different "depths of field".

Lentils are lens-shaped pulses that have a short cooking time and a distinctive earthy flavor. Whole dried lentils are usually brown in color and frequently used to prepare an inexpensive, yet nutritious soup all over Europe and to a lesser degree North America.
In India, lentils are mostly found in split (Dal) form. Stripped of their outer skin, split lentils are usually bright orange in color. The thick, spicy stew prepared from lentil and other Dals is also known as Dal.
The optical lens is so named after the lentil (German: Linse), whose shape it resembles.

A photographic lens (or more correctly, objective) is a lens used for a camera. It may be fixed to the camera body, or interchangeable. There will usually be an aperture selection mechanism for adjusting the amount of light through the lens, and a focussing mechanism. Depending on type of camera, there may also be an integrated shutter.The maximum aperture opening will normally be specified, as the f-number. The lower the number, the more light is admitted through the lens. On lenses for SLR cameras, there is usually an auto mechanism, where by the aperture is held fully open while focusing, but closes to its preset value when an image is taken.
The most important characteristic is the focal length, which is usually measurd in mm (cm up to around 1960), and which places the lens in one of three categories:
Some notable photographic optical lens designs are:
- Normal lens
- Telephoto lens
- Wide-angle lens
