Product Information

The Single-Longitudinal-Mode Solution, SLM series, diode laser modules for stable, high power illumination requirements. The latest module in the line, the SLM-632, may be the perfect drop-in replacement for HeNe lasers. This compact, high power SLM-632 delivers up to 50 mW of stable output power at 632.8 nm in a compact turnkey form factor at a very economical cost.

The SLM-632 can be operated over the temperature range of 0° – 40°C. The small compact form factor, 86 cm3, 135 grams, requires only a 3.3V/2A supply.
