International Light has instruments designed for simple laser power measurements in the visible and near IR that can be used even by non-technical personnel.

The IL1455 Laser Power Radiometer has an internal integrating sphere in the SPL024F detector that ensures proper beam aiming, with a uniform translation response and a flat response over its spectral range of 350 to 1060 nm. With a measuring range from 100 nanowatts to 300 milliwatts that reads out alphanumerically in SI units, the IL1455 is a low cost, simple, accurate system for measurement of low power continuous lasers such as Argon, HeNe, NdYAG, and laser diodes.

The IL1755 Research Radiometer offers more powerful features for measuring CW (continuous wave) lasers and laser diodes for pulses greater than 5 µS. the SED033/F/QNDS3/H/N/K15 detector has a flat spectral response from 400 to 1000 nm, a uniform angular spatial response over its large, 1.7 cm2 input aperture, and a dynamic range from 5 microwatts to 200 Watts. (At 200 Watts the maximum exposure time is 40 seconds). The SAP calibration is available for the IL1755 system, providing sensitivity factors every 10 nm over the spectral bandbass of the detector.
