    BSW biconcave lens
    Introduction:
    A biconvex lens has two inward facing, identical curved surfaces and a negative focal length, which are used to form a reduced image or diverge light. A biconvex lens has a negative focal length, making it most suitable for diverging and converging light beams. A biconvex lens can diverge a collimated beam to a virtual focal point, and is usually used in Galilean beam expanders. Products with coatings have better transmittance.
    Technical parameters:
    Materials: optical glass and silicon, germanium, zinc selenide, zinc sulfide, fluoride, sapphire
    Diameter 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
