Opnext Blue-Violet Laser Diodes (404nm - 445nm)

With more than 30 years of industry experience, Opnext offers blue-violet laser diodes from 404nm to 445nm and output powers from 60mW to 400mW (typ.). These high quality and reliable laser diodes feature high powers and low operating currents.

The new 445nm 80mW single transverse mode blue laser diode, the HL45023TG, is ideal as the blue light source for RGB laser pico projectors.

The 404nm, 500mW multi transverse mode violet laser diode, the HL40023MG, is suitable for direct imaging for printed circuit boards and medical analysis equipment.

All Opnext laser diodes are RoHS compliant.
