Description
Our 15.0 mm EFL visible broadband collimator lenses are engineered for 400–700 nm laser diodes requiring reduced beam divergence for medium-to-long range applications.
Featuring a precision optical glass aspheric element with >96% average transmission BBAR coating across the full visible spectrum, these lenses are supplied as unmounted singlets or pre-assembled in M9×P0.5 / M10×P0.5 threaded metal barrels with focus-adjustment capability.
Ideal for long-distance pointers, industrial alignment tools, structured light projectors, and OEM VIS LD packaging.
Custom EFL (3.77 / 4.05 / 6.2 / 8.0 / 9.795 / 13.55 mm etc.), element diameters, and narrow-band coatings available on request.
