The instrument is a high stability of helium-neon laser, the use of imported hard to seal the whole cavity of a dedicated high-quality laser tube, with unlimited long storage life and the life of more than 10,000 hours, a unique frequency stabilization technology and fully enclosed structure design,so that the machine has a compact, safe, reliable, easy to use features.

The stability of the wavelength, it has a longer coherence length, and better wavelength accuracy, especially in the field of high-precision coherent measurement.

The main parameters:

● output power: ≥ 0.8mW.

● Power stability: better than 1%.

● Frequency stability: better than 1 × 10-7.

● Beam Divergence: 1.7mrad.

● beam to be diameter: 0.48mm.

● the size of the laser head: Φ32mm × 200mm.
