H-K9L/Fused Silica/Sapphire Optical Cylindrical Plano Concave Lens
H-K9L/Fused Silica/Sapphire Optical Cylindrical Plano Concave Lens
Item Number:X-P22C8N0701B
Cylindrical lens is usually used as a laser line generator, or to adjust the image height or correct astigmatism in the imaging system.Cylindrical Lenses have a single cylindrical surface that causes incoming light to be focused in only a single dimension, stretching the image. Cylinder Lenses are available with positive or negative focal lengths, ideal for laser line generation or anamorphic beam shaping to circularize laser outputs.

What is cylindrical lens?
Cylinder Lenses are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylindrical Lenses have a single cylindrical surface that causes incoming light to be focused in only a single dimension, stretching the image. Cylinder Lenses are available with positive or negative focal lengths, ideal for laser line generation or anamorphic beam shaping to circularize laser outputs.

Types of cylindrical lens:
● Plano-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light.
● Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.
● Double-Convex Lenses are used in image relay applications, or for imaging objects at close conjugates.
● Double-Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. DCV Lenses are used in a range of industries or applications.
Cylindrical lens from VY
VY Optics offers a wide variety of Double-Convex Lenses in a range of substrates or anti-reflection coatings for maximum performance in the Ultraviolet (UV), Visible, or Infrared (IR). Anti-reflection coatings include UV-AR, UV Fused Silica or Calcium Fluoride (CaF2) substrates are also available for additional performance in the Ultraviolet (UV) or Infrared (IR) spectrums. UF Fused Silica Double-Convex Lenses are ideal for close conjugate imaging systems utilizing Ultraviolet (UV) illumination. Calcium Fluoride (CaF2) offers a very wide transmission range of 350nm - 7μm.

Most commonly used and the earliest example of an achromatic lens is the achromatic doublet. An achromatic doublet is made from a pair of glasses, of which one is typically a concave and another is convex. The concave element of the doublet is composed of flint glass (with higher dispersion); the convex element, however, is made up of crown glass (with low dispersion). These two elements are placed (cemented) next to each other in such a manner that the chromatic aberration of the one element is balanced by the chromatic aberration of another. There are various types of achromatic lenses, which differ in the type of lens elements and optical properties.
