Spectral Light Meters, UV-VIS-NIR Spectroradiometers

Spectroradiometers for use as portable devices and fixed installation systems for measuring the spectral distribution of sources over the UV-visible-NIR wavelength range in absolute units. We offer all kind of versions for spectral ranges starting at 200 nm to 2150 nm. Direct input optics, optical fibers, radiance optics, etc.

We are a manufacturer of high quality spectroradiometers and spectrophotometers 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 filter methods for stray light correction 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, VIS to NIR and applications. 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 devices as well our mobile devices like the BTS256-EFBTS256-LED 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 mobile devices.

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