Calibration of power meters

Benefit description

Calibration of optical power meters both in air, in the spectral range between 250 nm and 1100 nm, and in fibre optics, in the spectral range between 600 nm and 1650 nm. The following services are provided: 1.- Calibration of power meters for fibre optics in the wavelength range between 600 nm and 1650 nm with the following characteristics: - The power correction constant (dB) or power calibration factor (W/W) is calibrated (recognised uncertainty 1 %), for values between -17 dBm (20 uW) and 0 dBm (1 mW). - Applies to wavelengths between 600 nm and 1650 nm. - Optical power meter linearity measurement (in dB or W/W), for values between -60 dBm (1 nW) and 10 dBm (10 mW) (only at 1550 nm). 2.- An economical variant is available in which the instrument is calibrated at only two wavelengths in the spectral range between 600 nm and 1650 nm. For more wavelengths, consult the laboratory. 3.- Calibration of optical power meters for plastic fibre. Calibration is performed at wavelength 660 nm, from 0 dBm to -45 dBm (other wavelengths on request). 4.- Calibration of optical power meters in air at two wavelengths and two power levels, in the spectral range between 250 nm and 1100 nm. It consists of the determination of the power correction constant (dB) or the power calibration factor (W/W). 5.- There is an economical variant in which the equipment is calibrated at one wavelength and one power level, in the spectral range between 250 nm and 1100 nm.
