Single emitter beam waist and spectral analysis
By implementation of a z-translation stage, the camera enables the characterization of the single emitter beam profiles. In this way, the single emitters can be characterized in terms of beam waist, numerical aperture and M² value. For analyzing the spectral parameters, the camera is optionally available in a version with fiber output. Connecting the VTC 4000 to a high-resolution CAS spectroradiometer enables measuring the peak wavelength of every single emitter. The VTC 4000 can be easily integrated into handler systems with x-, y- and z-translation stages. This enables automated characterization of complete VCSEL arrays.
Key features:
- 2D measurement solution for near field characterization of VCSEL arrays
- Radiant power, polarization, position, divergence and peak wavelength for all single emitters
- Flat-field and absolute power calibration, traceable to national metrology standards
- Easy software integration by LumiSuite SDK
