可调谐光源（TLS）/ Tunable Light Sources (TLS)

产品详情

Test Standard: CE Compliant.

Sciencetech offers a series of computer-controlled adjustable sources of monochromatic light, our Tunable Light Source (TLS) line. Each TLS system is pre-aligned at the Sciencetech test lab and packaged with the system’s test data and detailed manual. Sciencetech’s tunable light sources are motorized instruments controlled by Sciencetech’s Windows based software. LabView drivers, ActiveX and DotNet modules are also available making the TLS a flexible system for integration with your experiment or instrument.

Test Purpose:

Sciencetech’s software, Sci-Spec, controls all components of the system. In the standard configuration, it controls the power supply of the light source, shutter, filter wheel, and monochromator. As an option, the user can add computer control on the input and output slits, and/or control of the iris. In the standard configuration, the output beam can be collimated or focused. Coupling with different devices is available as an option, such as coupling with a sample chamber, fiber, or fiber bundle.

Applications: Absorption / transmission / reflection measurement systems, Operable as an excitation light source in fluorescence, measurement systems, Eye protection products measurement system, PEC photochemistry measurement systems, Solar cell quantum efficiency measurement systems.
