Product Description

2023 Export Quality OEM/ODM Service Custom Magnifying Glass Lens 2X 3X 5X Large Double Convex 127mm Optics Biconvex Desktop

Double-Concave lens, also named Bi-concave lens, is usually made of flint glass and used for beam divergence. It's focal length is negative but the parallel incident ray diverges outward. The two sides of the biconcave lens curvature radius can be equal or not. Combined with plano-convex lens, it is generally used in beam expanders, projection optical systems and optical viewers etc.

Parameters:

Output Power: None
Wavelength: for 532nm
Dimensions diameter: 5mm/8mm

Lens Material: Glass

Application:

They are double concave glass lenses for 532nm green laser Beam Expander! This laser lens is a high permeability optical component used for as Industrial testament, Lab, DIY. Especially for the green laser pointer, laser flashlight and low-power green laser module. Get a clearer laser effect than plastic lens.
