Laser marking machine beam expanding lens laser cutting head lens
Features of Planoconcave Lens:
The planoconcave lens has a concave side and a flat side. It is with negative focal length, usually used for beam collimation, increasing (decreasing) focal length, or enlarging (decreasing) image. In order to get a smaller spherical aberration, It should be incident on the concave surface of the planoconcave lens when the incident beam is a collimated beam.
Application:
Planoconcave lens is often used for imaging or beam collimation, and the coated lens is also widely used in visible light and near infrared applications.
