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.

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.

Software Control

Measurements with the IDR300-PSL are fully-automated using the BenWin+ spectral acquisition software whilst guidance and reporting is provided by the PSL Wizard. Key features include:

Automatic rough positioning with overview camera

The TEL310 is available with a positioning camera with which you can trivially position the PSL-ALIGN stages to align your sample to the telescope. The image has an indicator to show what positions the stage can move to, and you can click on the image to reposition the stages. There are also buttons to move to the current peak, either in a single movement or iteratively. 

Automatic fine positioning with telescope camera

An image is produced inside the telescope on the aperature that selects the field of view for the monochromator measurement. This image can be inspected with a camera inside for complete understanding of what light passes through the telescope. By selecting no aperture, the stages can be fine-tuned to optimise the alignment, again by clicking on the desired spot on the image, or automatically.

Precise selection of target area

Combining these methods, it is quick, simple, and clear which light passes through the telescope. In this image, a 5 mrad aperture was selected.
