15 PCS Red Laser Glass Collimating Lens [630nm-680nm] package contains 15 pieces of a highly transparent coating focusing lens with M9 P0.5 metal frame, which is specialized for common laser diode set (cases), to collimate produced coherent light of laser diode with red laser spectrum from 630nm to 680nm wavelength. This lens should be ever clear and clean, so while working or storing, be careful of scratching in contacts with harsh surfaces or staining in contact with smeary things.
A laser diode, (LD), an injection laser diode (ILD), or diode laser is an especial semiconductor P-N junction, to emit coherent light with a narrow spectrum. Two big challenges of laser diodes projects are proper heat control (heat dissipation) and proper powering supply (diode driving). Therefore laser diode should be attached on the heat conductive case (copper, aluminum, and so on) to export diode heat producing into this body. Also, an optical lens is placed on the body to focus the laser beam.
