Description
M9×P0.5 Collimating Lens for 405nm Violet & 445nm Blue Laser Diodes — EFL 8.3mm, BBAR 405–450nm
Our M9-threaded violet/blue-laser collimator lenses with 8.3 mm effective focal length are optimized for 405–450 nm emitters including violet (405 nm) and blue (445/450 nm) laser diodes.
Featuring a molded glass aspheric element with >97% transmission BBAR coating over the UV-VIS blue band and a precision M9×0.5 fine-thread metal housing for focus adjustment,
these compact assemblies deliver tight beam collimation for violet/blue dot/line modules, show lasers, fluorescence excitation sources, and OEM LD packaging. Custom EFL (4.05 / 6.2 / 12.0 mm etc.), threads (M6/M10/M12), and visible-broadband coatings available on request.
For Collimating lens, the focal length we have 3.77mm,4.02mm, 4.39mm,6mm,6.2mm ,6.5mm,8mm, 8.3mm, 9.8mm, 10mm,11.2mm and 12mm.
Applications:
Violet / Blue Laser Modules — 405 nm / 445 nm dot, line, cross laser pointers and projectors
Entertainment / Show Lasers — Blue/violet DPSS or LD source collimation for light shows
Fluorescence Excitation / Raman Setup — 405 nm collimated source pre-stage
Machine Vision / Alignment — High-visibility blue guide lines on low-contrast surfaces
OEM Violet/Blue LD Packaging — Screw-in collimator for M9-standard laser diode holders
Lab / Scientific — 405–450 nm diode beam conditioning and collimation
