K9 Plano convex lens

plano convex lens

K9 plano convex spherical lens can see the transmittance of near infrared (350-2000nm).

H-K9L (N-BK7) is an optical glass commonly used in the preparation of optical elements.

The collimated beam can converge on the rear focus, or the point light source can be changed into a collimated beam.

Plano convex lenses are ideal for focusing parallel rays at one point. These lenses can be used in a variety of applications. They have proven focal lengths and have near optimal shapes for infinite and finite conjugate applications. The plano convex lens can focus the collimated beam on the back focus, or turn the point light source into a collimated beam
