The RADIANT QX tunable laser series utilizes optical parametric oscillator technology to generate wavelengths over a broad range in the Ultra Violet (UV), Visible (VIS) and Near Infrared (NIR). Integration of system components into one compact unit increases ruggedness, minimizes misalignment and allows the user to reposition the system. Included verification hardware enables the user to confirm that beam paths are preserved after shipment or relocation; no expensive or time-intensive installation required. Hermetically sealed modules protect sensitive optical materials from the environment. All tunable beams exit the system from the same port. Wavelength tuning is motorized and computer-controlled.
