Photobiological safety testing to international standards require a measurement capability spanning the 200-3000nm spectral wide range in consideration of six hazards to the skin and eye. The IDR300-PSL spectroradiometer facilitates the required series of measurements of spectral irradiance and spectral radiance whilst ensuring full compliance with the recommended measurement instrumentation.

With full hardware automation and full measurement guidance, calculation and report generation, the IDR300-PSL is at the heart of photobiological safety testing in accreditation and light source manufacturers laboratories throughout the world.
