As the worlds leading supplier of Helium Neon lasers, Melles Griot offers a broad selection of products for applications requiring unmatched M2 performance, narrow linewidth, stable frequency and long operating lifetimes at affordable prices.

Products include 543 nm green and 633 nm red with randomly or linearly polarized output. We also offer frequency stabilized models with frequency stability better than 1 MHz. The standard product offering includes fully turnkey systems including the laser head and controller, and for OEM’s we offer plasma tubes or custom-tailored configurations.
