The photometry infrastructure has state-of-the-art equipment that has a 1m diameter integration sphere and a lux meter.
Able to perform measurements of the following quantities:
- Total luminous flux
- Luminous intensity
- Dominant wavelength
- Radiation diagram in the 350nm to 750nm range
- Radiation spectrum
- Variation of power to determine the best luminous efficiency (applicable to LEDs)
- Determination of CRI (color rendering index) and CCT (correlated color temperature)
Standards
- CIE 1931 color space
- CIE 1976 UCS – CIELUV uniform chromaticity diagram
