IDR300-PSL Photobiological Safety Spectroradiometer

Test and certification companies and lamp and luminaire manufacturers can now evaluate the photobiological safety of lamps and lamp systems easier, faster and with greater accuracy than ever before.

err

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 manufacturer’s laboratories throughout the world.
