CRYLINK’s 633 nm laser is Narrow linewidth laser system of NLM series.It is used in confocal microscopy,raman spectrum detection,fluorescence spectrum detection,particle size detection,He-Ne laser replacement and other fields.

633nm Narrow Linewidth Laser System of NLM Series

633nm is one of the most widely used standard wavelengths at present. The 633nm narrow linewidth semiconductor laser system introduced by our company adopts the volume Bragg grating (VBG) wave locking technology, which enables the semiconductor laser to achieve narrow linewidth and stable power output. It can replace the traditional He Ne exciter in many fields. At the same time, compared with the He Ne laser, it has the advantages of compact structure and continuously adjustable power, Two output modes, spatial collimation and fiber coupling, can be provided.
