Tunable Light Source

SCIENCETECH offers a series of computer-controlled adjustable sources of monochromatic light, our Tunable Light Source (TLS) line. These complete plug-and-play systems vary by functional spectral range, optical resolution, intensity of output light, optical parameters of the output beam, coupling options, accessories, and by different extent of automation


The standard configuration of a TLS includes a lamp housing with Xe or QTH lamp, power supply with touchscreen, monochromator (1/8 or 1/4 meter), automated 6 position filter wheel (with 4 long pass filters) mounted to a metal breadboard to create a compact, fully assembled illuminator. Each system is pre-aligned during production and packaged with the system’s test data and detailed manual. Sciencetech’s tunable light sources are motorized instruments controlled by Sciencetech’s TLS software. LabView drivers are also available for purchase for integrating Sciencetech’s TLS systems into LabView experiments
