Vacuum blackbodies for cryogenic or ambient irradiative environment
- Absolute temperature range from 100K to 425K
- High thermal uniformity and emissivity
- Use of vacuum compatible coatings and materials
Vacuum blackbodies combine the performance of traditional infrared reference sources with specific features in order to operate in a vacuum chamber, at cryogenic or ambient temperatures. They can emit over an ultra-extended temperature range, set and controlled with high accuracy.
A vacuum compatible emissive head is connected to a controller located outside the chamber. High stability of regulation is ensured by the optimized control of the losses through radiation and conduction.
The temperature of the emissive surface is measured in real time via high precision calibrated Pt sensors. High emissivity up to 0.999 is obtained due to a vacuum compatible coating on a specific surface structure of the blackbody.
Various principles of thermal exchanges are available to suit different applications such as non-uniformity correction of infrared sensors and characterization and radiometric calibration of spaceborne imagers and...
Integrated tests with LabVIEW driver
For its full range of blackbodies, EOI provides a full-featured LabVIEW driver, compatible with LabVIEW v8 or higher and for all available communication links Ethernet, RS232 and IEEE.
Directly available from the LabVIEW menu are all the required VIs. These functions allow the operator to read the current temperature, send a temperature setpoint, check the stabilization status, among many other functions. For ease of use, the supply also includes an example program built with all the available VIs.
With this driver, all EOI’s blackbodies can be integrated into complex test benches running automatic infrared characterization routines and are fully controllable.
