Product Description

2023 High-end Customization Export Quality OEM/ODM Service Factory Wholesale Price 4" Spinning Top Base (Rounded by Silicone), 30cm Focal Length (Double Concave), 100mm Large Gyroscope Station

Product Description

 

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.
