Spectral Light Meters, UV-VIS-NIR Spectroradiometers

We are a manufacturer of high quality spectroradiometers and spectral light meters for numerous applications. The instruments are developed, built and characterized in-house in our ISO17025 calibration laboratory. The expertise in our comprehensive calibration laboratory with its extensive measuring equipment, including a tunable laser, enables us to characterize and correct our devices very precisely (e.g. stray light correction matrix, bandpass correction, non-linearity correction) as well as optimize them already during development. Particular the optical characteristics such as the highest imaging quality in very small mobile devices as well as innovative technologies like the BTS technology (mutual correction with integral sensor) and optical filter methods for stray light correction of array-spectroradiometers make our spectroradiometer superior. The use of high-quality CCD and CMOS sensors, some with electronic shutters and integration times in the µs range (allows a factor of 1000 higher dynamic range by just integration time compared to conventional devices) as well as high-quality optical components such as mirrors and gratings are all part of our philosophy.

Over the years, we have developed a variety of device variants to cover a wide range of spectral ranges from UV, Visible to NIR and applications (200 nm to 2150 nm). Devices can be equipped with various entrance optics directly mounted or configured for use with optical fibers. Laboratory, industrial or weather proof devices, as well as mobile handheld or orientation-independent devices for goniometers are available. See for instance our BTS2048 Series and this spectroradiometer BTS2048 brochure.

Beside this high-end spectroradiometer devices as well our mobile spectral meters and spectral lux meters like the BTS256-EF, BTS256-LED Tester and  MSC15 or  CSS-45 are highly attractive when it comes to application orientation like flicker measurements, PAR measurements, single LED testing with highest accuracy for spectral measuring mobile devices.

We are as well able to absolute calibrate the spectroradiometers in the needed radiometric quantities. Spectral irradiance, spectral radiant power or spectral radiance. Depending on the application and the system setup, e.g. input diffusors, fibers, radiance optic.
