BZPW cylindrical flat concave lens Introduction: A negative cylindrical lens acts similarly to a flat concave spherical lens, but the former only functions on one axis. These cylindrical lenses are used for applications that require shaping point light sources in a one-dimensional direction. A typical application is to use a single cylindrical lens to convert a collimated laser beam into a linear beam. A pair of cylindrical lenses can be used to shape images. To minimize spherical aberration, when diverging the beam, the surface of the lens should be oriented towards the light source. Technical parameters: Materials: optical glass and silicon, germanium, zinc selenide, zinc sulfide, fluoride, sapphire Dimensional tolerance:+0/-0.01~+0/-0.1mm Thickness tolerance: ± 0.01~± 0.1mm Face type: λ/ 10~ λ/ 2@632.8nm Finish: 10/5~60/40 Eccentricity:<30 "~3 ' Effective aperture:>90% Chamfer: Coating: antireflective film, bandwidth antireflective film
