High Volume Laser Diode and VCSEL Testing
Hitherto established measurement technologies for laser diodes – such as dispersive scanning spectrometry and Fourier-transform infrared spectroscopy (FTIR) – can react sensitively to a production environment. High-resolution array spectroradiometers are effective alternatives that offer multiple advantages, also in continuous production.
Laser diodes, and in particular vertical-cavity surface-emitting lasers (VCSELs), have experienced rapid market growth due to new applications and new technological approaches. Examples of this are infrared VCSELs integrated into consumer electronics and direct diode lasers based on VCSEL arrays, replacing conventional laser systems.

Stray Light Correction for Array Spectroradiometers
The core competency of Instrument Systems is providing high performance array spectroradiometers, e.g. the CAS 140D that features highest measurement accuracy and reliability. Quality and accuracy of a spectrometer are extremely important because all radiometric, photometric and colorimetric quantities are calculated from the spectral data. A considerable source of error is the occurrence of stray light in the device. This means that a certain pixel of the array detector is contaminated by radiation other than the targeted spectral component.

Redesign of BTS256-EF Light, PAR and Flicker Meter
The lighting industry requires high accuracy spectral light meters that can handle complex measurements. These include measurement of pulse width modulated light sources and the ability to measure both indoors and outdoors lighting, determination of thermal transient behavior of lamps, their flicker properties and so on. The primary criterion that such meters must always meet is the quality of their photometric features.

Photobiological Measurement System from GL Optic for Highest Safety Standard
The photobiological safety measurement system from GL Optic – in short: GL PSM System 200-800 nm is the world's first mobile and preconfigured measurement system for monitoring and assessing the blue light hazard of all types of lamps. Blue light hazard (photoretinitis) is defined as the potential risk for a photochemically-induced retinal injury resulting from electromagnetic radiation exposure at blue wavelengths of 400-500 nm.

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 task, as an underestimation of the blue light hazard was possible in measurements with a spectroradiometer on array spectrometer basis due to stray light. The CAS 140D avoids this in two ways: The optics and mechanics used in the spectrograph block are optimized with regard to disturbing stray light. Additionally, a unique stray light correction matrix is integrated in the calibration procedure. Both innovations combined ensure an up to now unachieved precision in the determination of the blue light hazard with an array spectrometer.
