The spec’3 spectral measurement system launched by Opsira GmbH rapidly measures spectral distributions from the UV to the near-IR. It succeeds the company’s spec2000 system and is based on a CCD detector with higher pixel resolution and extended analog-to-digital converter resolution. The control and evaluation software has been redesigned, and color tolerance areas can be defined to perform quick tests with respect to specifications. In the visible region, the colorimetric values are displayed directly according to CIE and, in continuous live mode, color rendering values are updated permanently. Automated adjustment of the integration time and of the integrated automatic shutter for dark correction stabilizes the system in an optimal working position.
