HINDS I/FS50-ATC Hinds PEM With Advanced Thermal Control

Manufacturer's part number :


Manufacturer Hinds


Description :

Hinds Instruments offers the PEM-ATC™, a photoelastic modulator with advanced thermal control. This PEM offers long term retardation stability and freedom from drift caused by ambient temperature fluctuations. This option is available for PEM head I/FS50 and I/FS60 models. The PEM-ATC is equipped with a proprietary PID controller, internal heating, and a temperature sensor. Through the use of heater operated PID feedback control, the interior of the PEM optical head is held at a constant 90°F or 32°C, even when ambient temperatures are fluctuating.
