from Shanghai Optics
These lenses are manufactured from SF11 for VIS and NIR applications and are supplied coated or uncoated. SF11 is generally used instead of BK7 to minimize aberrations from short focal length lenses. The higher refractive index provides for a less-steeply angled surface and a better transmitted... [See More]

PCV Cylinder lenses are commonly used to turn a collimated laser source into a line generator. PCV and PCX oblong cylinder lenses can be used together for beam expander applications.The thin lens approximation for the length of a line generated by a negative cylinder lens is: L = 2 * (r0/f) * (z +...
