Diameter 5mm H-K9L Cylindrical Rod Lens for Endoscope

Diameter 5mm H-K9L Cylindrical Rod Lens for Endoscope

Cylindrical lenses have a spherical radius in one direction. This enables the light to be focused in one axis. Point of light can be stretched into a single line. It can be used in a variety of different applications, including bar code scanning or laser projection, collect, focus and diverge light and are often components of lens systems that perform an achromatic function for example. We supply cycindrical plano convex lens and spherical plano convex lens These cylindrical lenses are designed for applications that require one-dimensional shaping of the source. They have a flat-concave and flat-convex structure, both for diverging or converging beams.

The base material is N-BK7 glass, UV fused silica or CaF2, and all materials can be selected from uncoated or AR-coated. We supply cylindrical lens,like cylindrical lens,plano convex cylindrical lens,half rod plano convex cylindrical lens,etc.
