Product Overview:

Lumentum 632.8nm HeNe Laser Head, 21mW Output Power

The Lumentum 1100 Series red helium-neon laser products offer low noise, high power stability, and long life for the most demanding applications. With more than 1.5 million units sold, Lumentum lasers are the industry standard for many advanced system designs.

Lumentum Expertise Powers Your Application

Lumentum manufactures helium-neon lasers in the red, green, yellow, and orange wavelengths. All feature our patented close-cathode design that rapidly and uniformly distributes discharge heat throughout the laser, resulting in excellent thermal, beam-pointing, and power stability. Our patented field concentrator design ignites the discharge within milliseconds of applying the start voltage. Hard-sealed internal mirrors, small physical size, and low noise result in greater reliability, longer life, and enhanced performance.
