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 are a manufacturer of high quality spectroradiometers and spectrophotometers for numerous applications. The instruments are developed, built and characterized in-house. 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) 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 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.
