Optical Technologies Laboratory


EVATEG optical laboratory facility has been equipped world class infrastructure such as goniophotometer, integrated sphere and luxmeters. Our system can measure, optical power spectral distribution, CCT, CRI, lumen, lux and light distribution. We pay extra attention for the calibration of our devices and systems. Our measurements are done for both research and accredited-report development purposes. Our technical team develops international conference and journal publications and frequently invited for delivering invited talks in both conferences as well as industrial or academic groups. Our integrated sphere has a 2 m enabling chip to large lighting fixture measurements. This system can make measurements according to IESNA LM79 standards for lumen, CRI and CCT. The system is well maintained to reach standard reflection values at the inner surfaces of our system.

Goniophotometer is another important system in our optical laboratory to measure light distribution for a variety of lighting systems. Our system can make measurements for lighting systmes as large as 1900 mm in length and 50 kg in weight. Our system makes measurements in 3D and our precision as low as 0.1⁰ degree.
