This red laser diode module employs qualified glass coated lens. It is performing better than plastic coated lens, getting no decay light in constant use. It keeps work with high transmittance red laser beam emission and highly clear red dot projection in distance. This compact size red dot laser enables easy installation and adjustment of laser beam focus and dot projecting direction, thus achieving no mistake and no barrier dot alignment effectively.
