Spectra Feature: Single and Multi-Mode VCSEL Testing
This Month’s spectra were contributed by a current Avantes customer in the manufacturing of Vertical Cavity Surface Emitting Lasers (VCSEL).
We utilize Avantes spectrometers to measure spectral peak wavelength, centroid, SMSR, FWHM, and RMS spectral bandwidth of a broad range of VCSEL-based laser products.
|Wavelength Range||650nm to ~1000nm|
|Laser Power||10’s of uW’s to 10’s of Watts|
|Modes||Single-mode to Highly Multi-mode Emission|
Platforms include high-speed wafer probe/die sort, final production test of packaged components, and general lab use.
Benefits of the Avantes System:
- Easy integration with python and dotnet software code base
- High sensitivity for reduced test time, particularly important for high-volume production test
- High pixel count for broad spectral coverage
- Good resolution
- Reliable and robust mechanical design
