YuTai
offers a variety of optical glass lenses and windows, such as
Cylindrical Lens, Optical Aspherical Lens, and CVD ZnSe Lens. YuTai
provides multiple anti-reflection coating options for the Ultraviolet
(UV), visible, or IR Optical Lens and also provides uncoated optical
Lens based on K9 optical glass, K7 and UV fused silica.

Biconvex lens
Biconvex
lens, also called double convex lens. It has a similar function to a
plano-convex lens, and both are positive lenses used to focus the beam.
The wavelength range used is 190-2100nm.
Biconcave lens
The
double-concave lens is similar to the plano-concave lens. The focal
length is negative, but the parallel incident light diverges outward.
The two side surfaces of the double-concave lens have the same radius of
curvature, and are generally used for beam expansion and projection.
Plano convex lens
Plano-convex,
the collimated beam passes through the lens to a point behind the lens.
We also call it a positive lens or a converging lens. The distance from
the lens to the focal point (called the spot) is the focal length of
the lens, which is usually abbreviated as f in diagrams and equations,
and usually we can call it EFL in the specification.
Plano-Concave Lens
Plano-concave, the collimated light beam passing
through the lens is diffused, and then we call it a negative lens or a
divergent lens. The light beam passing through the lens appears to be
emitted from a specific point on the front axis of the lens. The
distance from this point to the lens is the focal length. We call it
negative film based on the comparison between plano-convex positive
film.
