Proof Your Blue Light Hazard Risk: Stray Light Corrected CAS 140D
With the stray light corrected CAS 140D Instrument Systems – as a technical pioneer – is the first to offer an array spectrometer that can reliably assess the blue light hazard from light sources within the prescribed limiting values. Hitherto only double monochromators were recommended for this…
In conformance with standards IEC 62471 and IEC 62778, extremely high quality requirements are placed on spectroradiometers when used for assessing the blue light hazard from light sources. In addition to the stray light behavior, sensitivity and wavelength accuracy are also relevant, since some of the assessment spectra used have extremely steep gradients. Through a new form of calibration the CAS 140D achieves a wavelength accuracy of measurements below the value of ±0.2 nm prescribed in IEC 62471. The improved mechanical and optical design significantly increases throughput. The stray light corrected CAS 140D thus satisfies the required standard limiting values for examining the blue light hazard and is an easy-to-operate alternative to scanning systems with reasonable pricing.
At Light + Building 2018, booth 4.1/K89, Instrument Systems will be presenting its latest stray light corrected array spectrometer CAS 140D for reliable testing of the blue light hazard emanating from white LEDs.
