Mechanical Light Shutter/Chopper for Ultra-Low Vibration and Precision Optics

The SH-65 device is a compact and cost-effective mechanical light shutter/chopper with ultra-low vibration performance. It is engineered to operate on optical bench setups, making it an invaluable component for vibration-sensitive environments demanding vibration-free conditions. Whether integrated into instruments or OEM products, this unit stands out for its ease of use and exceptional cost-effectiveness, particularly in high-volume applications.

Key Features

Rotary actuator driven with a 0.65" (16mm) aperture.
Constructed with a 0.010" thick black anodized aluminum blade. Other thicknesses are available.
Swift transition time of 10 milliseconds between end positions, accompanied by minimal shock or vibration.
Total blade swing covers 30 degrees.
Smooth transitions between open and closed positions without any clicking noise or hard stops.
Other blade finishes available, such as bare aluminum or bright nickel plating.

Versatile Functionality

In addition to its function as a mechanical light shutter, the SH-65 excels as a low-frequency optical chopper, offering frequencies ranging from DC to 25Hz.

DSH-65 Driver: Tailored Control for Model SH-65 Shutter/Chopper

The DSH-65 driver is purpose-built to provide precise control over the SH-65 shutter/chopper. It operates in two distinct modes:

Internal Mode: Utilize the SH-65 as an optical chopper, with adjustable chopping frequencies ranging from 0.5Hz to 25Hz, controlled by the internal oscillator.
External Mode: Employ the SH-65 as either an optical shutter or chopper. A TTL input manages the blade position, with "High" (5V) keeping the shutter open and "Low" (0V) keeping it closed. The shutter responds swiftly to the TTL input within 10 milliseconds. The maximum TTL input frequency supported is 25Hz.

Ordering Information
