Two versions of the fiber-coupled He-Ne-laser for the Interferometer VI-direct series are available. Depending on the application a non-stabilized or frequency stabilized version can be ordered.
He-Ne-laser is a typical gas laser with CW-mode. It emits in the visible range at 632.8 nm wavelength and is very common in scientific applications. One further benefit is its relative simple set-up. This guarantees a high reliability and easy handling of the laser.
