Video Tutorial - OL 770 Use for Source Spectral Analysis
Measurement - OL 770 Spectroradiometer Measurement System
This videos shows how to setup the OL 770 High-Speed Spectradiometer and its Application Software for general source spectral analysis. Measurements are presented e.g. for:
- Spectral radiant flux (W/nm, lm)
- Spectral radiant intensity (W/sr nm, cd)
- Spectral radiance (W/sr m²nm, cd/m²nm)
Large Integrating Sphere Measurement Systems
The measurement uncertainty of large integrating sphere systems crucial depends on a proper optical design.
The presentation shows a 1 meter version with its properties of:
- High reflectivity of diffuse sphere coating
- Reduction of measurement uncertainty due to optimized baffle design
- Use of traceable calibration lamps and concept of auxilliary lamps
- Requirements onto stabiliy of electrical power supply
