Characterization of laser diodes
As a participant at the German Pavilion at Photonics West / USA, Instrument Systems will be presenting its premium-class spectroradiometers and combined measurement solutions, complemented by absolutely calibrated cameras.
Since a clearly defined error budget of the measurement system is required, in particular for eye safety assessment in the measurement of lasers, e.g. VCSELs, Instrument Systems offers absolutely calibrated measuring instruments with traceability to the PTB. Systems consisting of integrating spheres, connected photodiodes and spectroradiometers can perform spectral and performance-related measurements of laser diodes and VCSELs at 940 nm.
Particularly fast photodiodes and suitably developed control electronics enable the time-resolved characterization of laser pulses in the nanosecond range. In addition, the single emitters of VCSEL arrays can be analyzed and conclusions drawn on the spatial radiation properties in the near and far field. All systems are available for laboratories, as well as for production applications with a focus on faster cycle times and an attractive price structure.
