optCRYO198 |
|
- Nitrogen continuous flow optical cryostat with external reservoir
Sample in vacuum or gas flow
 The optCRYO198 is universal nitrogen continuous flow cryostat with temperature control system and external dewar with N2. Liquid nitrogen continuously flows from a storage dewar into the sample room of the cryostat via gas-generator, forming the vapor flow. The electronuc unit controls the temperature of the N2 vapor and the flow rate.
The system is compact and easy-to use for any kind of optical experiments. The cryostat has two perpendicular optical channels with different spectral bands. In order to change the spectral band the cryostat has to be rotated by 90 degree around its axes.
