Photobiological safety spectroradiometer

IDR300-PSL from Bentham

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.

Features
  • Double monochromator-based spectroradiometer (200-3000nm)
  • Irradiance : Precision transmission diffuser coupled to IDR300 with 1m long quartz fibre bundle
  • Radiance : Direct view telescope permitting measurement from 200mm to 10m in key 1.7, 5 and 11mrad FOVs. Coupled to IDR300 with 1m long quartz fibre bundle.
  • Photometric detector with virtual luxmeter operation for determination of illuminance (500 lx, dthr)
  • Quartz halogen and deuterium irradiance standards, supplied with calibration traceable to PTB, Germany
  • Quartz halogen, integrating sphere-based radiance standard, supplied with calibration traceable to PTB, Germany
