SureLock™ 785nm Collimated, Wavelength Stabilized Laser Diode

Ondax’s 785nm Wavelength Stabilized Laser is a high-power, multimode, collimated laser packaged in an ultra-compact, TO-can footprint. The narrowed linewidth, low power consumption, and broad temperature operating characteristics deliver affordable, portable instrument-quality performance for a broad range of instrumentation applications.
All SureLock™ Series lasers are stabilized using the Ondax PowerLocker® Volume Holographic Grating, ensuring precise, ultra-stable center wavelengths, low temperature dependence, and consistent optical performance over the locked region.
