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

The SH-35 model, a compact and cost-effective mechanical light shutter/chopper, boasts ultra-low vibration characteristics. It operates seamlessly on optical tables, making it an invaluable component for vibration-sensitive environments. Whether integrated into instruments or OEM products, this device stands out for its ease of use and exceptional cost-effectiveness, particularly in high-volume applications.

Versatile Functionality

In addition to its function as a mechanical light shutter, the SH-35 excels as a low-frequency optical chopper, offering frequencies ranging from DC to 50Hz.

DSH-35 Driver: Tailored Control for Model SH-35 Shutter/Chopper

The purpose-built DSH-35 driver provides precise control over the SH-35 shutter/chopper. It operates in two distinct modes:

Internal Mode: Utilize the SH-35 as an optical chopper, with adjustable chopping frequencies ranging from 0.5Hz to 50Hz, controlled by the internal oscillator.

External Mode: Employ the SH-35 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 5 milliseconds. The maximum TTL input frequency supported is 50Hz.

Ordering Information

Example 1: Part No. SH-35 with DSH-35-PC This part number specifies the model SH-35 shutter, with a 0.010" thick black anodized aluminum blade and a front plate for horizontal and vertical mounting. The DSH-35 driver is a 3.93" x 2.6" populated printed circuit board driver, operating from an external 15 VDC power supply.

Example 2: Part No. SH-35-M with DSH-35-220-BNC This part number specifies the model SH-35 shutter, with a 0.010" thick aluminum blade and base for horizontal and vertical mounting, without a front plate. The DSH-35 driver is cased (5.3" x 5.3" x 2") 220VAC, with a selector switch for operating from a line voltage of 220Vac, with a BNC connector for TTL input.

Example 3: Part No. SH-35-MP-BRIGHT with DSH-35-110 This part number specifies the model SH-35 shutter, with a 0.010" thick bright nickel plated aluminum blade. The DSH-35 driver is cased 5.3" x 5.3" x 2", operating from a line voltage of 110 VAC.

Example 4: Part No. SH-35-S-BARE with DSH-35-110/220-BNC This part number specifies the SH-35 shutter with #2-56 threaded standoffs and a 0.010" thick bare aluminum blade. The DSH-35 driver is cased 5.3" x 5.3" x 2", with a selector switch to operate from either 110 VAC or 220 VAC line voltage with a BNC connector for TTL input.
