OPTICAL RADIATION

Traceable to our primary standard for optical radiometry - cryogenics radiometer, and primary standard for optical radiation source, we provide measurement services in radiometry for photodetector spectral responsivity scale characterization, solar cell efficiency measurement, fiber optics measurement, laser power meters, UV meters, and so on. For fiber optics, we do calibration or testing for OTDR, fiber optics source, fiber optics power meter, optical spectral analyser, wavemeter.

Services Provided:

• Photodetector spectral responsivity calibration: 250 nm – 1640 nm
• Calibration for reference solar cells: efficiency, I-V, short circuit current, under standard testing conditions
• Calibration of laser power meters and laser measurement: 400 nm – 900 nm
• Calibration of UV meters: 254 nm, 312 nm, 334 nm, 365 nm, 405 nm, 436 nm
• Calibration of Fibre Optic equipment, and measurement of fiber optic devices
• Fiber optics power at 850 nm, 1300 nm, 1310 nm, and 1550 nm
• Optical spectrum analyser calibration at 1310 nm and 1550 nm
• Fiber distance, optical attenuation and return loss of OTDR at 1310 nm and 1550 nm

We provide measurement services in photometry for color, spectral transmittance/reflectance, illuminance meters, lamps and LEDs. For lamps and LEDs, we do measurement for luminous flux, luminous intensity, spectrum, spectral irradiance and so on.

Services Provided:
