Dual frequency stabilized HeNe laser
Model：LGN-303
Overview
As a single longitudinal mode high stability He Ne laser, lgn-303 series frequency stabilized HeNe laser can emit two channels of vertically intersecting polarized single frequency light, and its coherence length is more than 300m. The ultra-high stability and polarization ratio make this He Ne laser widely used in various fields such as precision measurement and spectral standard.Description
