And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings.

A biconvex lens focuses light into a point with a positive focal length and consists of two convex surfaces with equal radii.

It is commonly used in imaging relay system and object imaging under limited conjugate distance.

The characteristic is that the larger the conjugate ratio, the greater the aberration.

A biconcave lens will radiate light with a negative focal length.

It is composed of two concave surfaces with equal curvature.

It is often used for beam expansion, projection and focal length expansion of the lens.

Borisun optics provides biconvex lenses without coating and with antireflection coating.

Antireflective film options include UV, VIS, NIR, and SWIR.

It is suitable for fused germanium or silicon violet, while it is suitable for fused germanium or silicon violet.
