Description UV CCD spectroradiometer vs. broadband CCD spectrometer The spectral responsivity of conventional CCD detectors usually lies within the 200 nm to1100 nm range. Often, this wide spectral responsivity range of the CCD detector is claimed as the responsivity range of the spectroradiometer. However, this fails to consider the spectral response function of the dispersion grating, which further reduces the detector’s responsivity in the UV spectrum. This results in significant errors in the UV measurement signal, primarily through long-wave stray light. The spectral resolution of broadband...

accessory components. With the diffuser window, the BTS2048-UV-2 can also be mounted directly onto accessories such as integrating spheres, radiance lenses, and goniometers in order to measure the radiant power, radiance, and radiance distribution. User software and developer software The standard S-BTS2048 user software has a customizable user interface and offers a large number of display and function modules which can be activated when configuring the BTS2048-UV-2 with the respective accessory components from Gigahertz-Optik GmbH. The SSDK-BTS2048 developer software is offered for the integration...
