Tunable to Five Wavelengths

Our tunable HeNe lasers can be tuned to 543 nm, 594 nm, 604 nm, 612 nm, and 633 nm wavelengths. Output power levels are 0.3 mW, 0.6 mW, 0.5 mW, 2.5 mW and 4.0 mW respectively. They are available for either 115 VAC or 230 VAC input power.

Optimized Cavity Mirror Performance

Utilizing enhanced designs and superior optical components these lasers deliver unsurpassed operational stability and lifetimes. The mirror quality and performances are optimized to result in the highest quality HeNe lasers available in the market. These high-performance lasers are supported by a one-year warranty and are available off-the-shelf.

HeNe Laser Advantages

HeNe Lasers use a mixture of Helium and Neon gas as the gain medium excited by an electrical discharge. Helium Neon gas lasers are based on a mature and well understood technology that offers a cost effective laser source with fundamental Gaussian beam quality, and ease of use. HeNe lasers offer a stable optical output over lifetimes greater than 20,000 hours and are insensitive to optical feedback.
