Ondax’s 638nm Wavelength Stabilized Laser is a single mode, single frequency laser packaged in an ultra- compact, TO-can footprint. The extremely narrow linewidth, broad temperature operating characteristics, and low power consumption deliver affordable, portable instrument-quality performance for a broad range of instrumentation applications.
All SureLock™ Series lasers are stabilized using the Ondax Pow-erLocker® Volume Holographic Grating (VHG), ensuring precise, ultra-stable center wavelengths, low temperature dependence, and consistent optical performance over the locked region.
