Description
M9×P0.5 Visible Broadband Collimating Lens — EFL 8.0mm, BBAR 400–700nm
Our M9-threaded visible broadband collimator lenses with 8.0 mm effective focal length are engineered for 400–700 nm laser diodes including violet, blue, green, and red emitters.
Featuring a molded glass aspheric element with >96% average transmission BBAR coating across the full visible spectrum and a precision M9×0.5 fine-thread metal housing for focus adjustment,
these compact assemblies deliver low-divergence collimated beams for multi-wavelength/RGB laser modules, pointers, alignment tools, and OEM VIS LD packaging.
Custom EFL (3.77 / 4.05 / 6.2 / 9.795 / 13.55 mm etc.), threads (M6/M10/M12/M14), and narrow-band coatings available on request.
