Spectraval 1501 is a precise and economic reference grade VIS spectroradiometer for various applications including monitor and projector calibration and the measurement of different display types. It measures spectral Radiance in the visible range and provides a variety of integral data.

Special versions of the device are spectraval 1501-HiRes (with an increased optical resolution), spectraval 1501-NIR (with a wavelength range up to 1000 nm) and spectraval 1501-LAN (with LAN interface instead of Bluetooth).

spectraval 1501 is also available in the following special versions:

  • scv 1501-HiRes
  • scv 1501-NIR
  • scv 1501-focus
  • scv 1501-LAN

The company was founded in January 1998 by three former Zeiss coworkers with the aim to develop, produce and sell spectroscopic equipment under the slogan “Economic and easy to use “. It has currently 14 employees. The main fields of activity are optics, electronics, mechanics and software development. So JETI can offer measuring systems developed “under one roof “.
