 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.
