New! Optical measurement systems from opsira

CBS Japan is the Japanese distributor for opsira GmbH's optical measurement systems and products used in general lighting, automotive, signal and medical lighting industries.

opsira’s robogonio goniophotometer combines near-field, extremely fast far-field, and spectral measurement in one single, highly flexible system.

opsira GmbH was founded over 20 years ago in August 1999 by Juergen P. Weisshaar and Volker Schumacher located in Weingarten, in the south of Germany and is one of the leading companies for the development of high-tech products in the fields of photometry, spectrometry, and goniometry.
