In the optics and photometry laboratory the unit of luminous intensity Candela (cd) is realized. The laboratory consists of the:

• Absolute Radiant Power Calibration Facility

• Spectral Responsivity Calibration Facility

• Photometry Calibration Facility

The activities of the laboratory include:

• Calibration of light meters and detectors at laser wavelengths

• Calibration of light detectors for spectral responsivity

• Calibration of lamps for spectral irradiance

• Measurement of Luminous Intensity of Tungsten filament lamps

• Calibration of luxmeters and photometers

• Measurement of Luminance of Tungsten filament lamps

• Measurement of chromaticity coordinates and correlated color temperature of sources
