UV-VIS Optical Spectrometer Ocean optics JAZ 3-channel (JAZ3-CHANNEL)

Spectrometers (Ocean Optics JAZ-3 and NIR-QUEST) available for general use in optical lab (or for short-term loan for in-situ measurements elsewhere in the facility) share common set of accessories. It can be used (usually with a reflectivity probe) to estimate layer thickness (or their homogeneity, in combination with mapping stage). We use either standard Ocean Optics software (OceanView) or custom-made software based on Java and TraitsUI for mapping.

NIR-QUEST
- Range 1000-2200 nm
- 256-pixel InGaAs detector
- Thermal control by Peltier cooling
