能量调置辐射源IR-762 IR-762 Energy Modulator
The IR-762 Energy Modulator is a variable speed rotating disk chopper designed for use with radiation sources, including blackbody, tungsten filament, mercury lamps, Nernst glowers and as part of instruments where modulated radiation is needed. The IR-762 has been specially designed to integrate with the IR-508 & IR-518 Blackbody Sources. For other applications a table mount is available. The IR-762 Energy Modulator system consists of the modulator head assembly and modulator controller. The controller operates the motor, blade rotation, and speed of the modulation frequency.
