In the IS12L-9S-RSI power meter, Gentec-EO uses the principle of the integrating sphere to close the gap between classic photodetectors and thermoelectric detectors. The inner coating of the sphere was developed by the manufacturer. With a maximum power density of 2 kW/cm² at 1064 nm, the damage threshold is considerably higher than that of other manufacturers. The result is a very wide measuring range from the µW range up to a cw output power of 9 W. This amount of high power clearly exceeds the capabilities of a commercially available photodiode. In addition to determining the performance of strongly divergent beams, this detector offers further advantages. Unlike photodetectors, the angle of incidence of the beam can deviate up to 10° from the ideal position without affecting the measurement result.
This instrument is traceably calibrated to NIST standards for the entire range between 405 nm and 1064 nm. With free software it can be operated directly on a PC via an integrated USB interface. A version with an RS-232 interface is also available on an optional basis.
