Page 4 - Plano-Concave Spherical

Plano-Concave Spherical Lens
Atoptical Co., Ltd
Plano-Concave Lenses are the best choice where object and image are at absolute conjugate ratios greater than 5:1 and less than 1:5 to reduce spherical.Plano-Concave lenses bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length.The spherical aberration of the ...

Zinc Selenide Lens
Alpha Optics
Zinc Selenide lenses are an excellent choice of materials for IR lenses for application between 600 nm to 16 microns wavelengths. Its low absorption coefficient makes it a perfect candidate for applications/instruments using C02 lasers. In mid IR regime it has a very low GVD which makes it suitable for applications using femtosecond ...
