能量调置辐射源IR-860 IR-860 Energy Modulator
The IR-860 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-860 has been specially designed to integrate with the IR-563 & IR-564 Blackbody Sources. For other applications a table mount is available. The IR-860 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. Interchangeable blades are available to allow modulation from 1.25 Hz to 45,000 Hz. The standard blade is an 8-slot blade with a frequency range from 10 to 1000 Hz.
