Spectrometer- Andor Mechelle 5000

Andor’s new Mechelle ME5000 spectrograph has been designed to provide simultaneous recording of a wide wavelength range (200-975 nm) in one acquisition. It has no moving components is available in a pre-aligned detector/spectrometer format. The Andor Mechelle spectrograph is based on the echelle grating principal and its patented optical design provides extremely low cross-talk and maximum resolution compared with other spectrographs.

Specifications:
Wavelength range (nm): 200 – 975
Focal length (mm): 195
Aperture: F/7
Spectral resolution (λ/∆λ): 4000
Wavelength accuracy: Better than ± 0.05 nm

Low Temperature optical investigation setup

This setup is suitable for optical reflectivity and transmission measurements. The setup is formed of an optical Nitrogen bath cryostat (Oxford OptistatDN) (77-500K) and a stabilized QTH (Quartz Tungsten Halogen) light source (100 W) with various interferential filters (from 400 nm to 900 nm). The transmitted/reflected beam is recorded via a photodiode. The temperature is controlled via an Oxford ITC503 Controller.
