FS35 35mm Optical Shutter
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Description
Current Lead Time: 6 – 8 weeks
The Uniblitz FS series shutters are designed and optimized to operate directly from +5VDC and do not require a separate driver. Removing the +5VDC (0VDC) closes these shutters. A simple control circuit can be used to operate these shutter devices from a TTL trigger pulse. This control can be also accomplished with our new VLM1 TTL control interface.
This low-cost innovation provides the reliability of Uniblitz shutters (typical lifetime >300K cycles) at a single operating voltage.
For the remote operation of FS series shutters from a TTL signal or USB interface, check out the VLM1 interface module.
If you find that you require an extended length in the FS Shutter Interconnection, this can be provided as an optional feature. By adding the “-5M” option to your shutter part number and acquiring the 510FS cable, this will extend the interconnection length to 10 ft (3m). Please contact a sales representative to add the “-5M” option and to purchase the 510FS cable. For further information on this option and other features, including a complete description of the FS device’s mounting options, please see the FS Series Optional Features document.

- Operation at +5VDC (open and hold) – Two wire operation, 18-inch flying leads for connection to the actuator coil Place +5VDC/0.5A on Red wire, +5V Return on Brown wire – Shutter opens. Remove +5V from the Red wire, shutter closes.
Figure #1: Sample drive circuit to control the FS series shutter from +5V TTL
Operation:
- To operate the shutter from a TTL signal, figure #1 illustrates a typical, simple circuit that can be used to open and close the shutter. Active High TTL on the TTL Input opens the shutter, Low on the TTL Input closes the Shutter. The FS35 Series Shutter will not operate directly from TTL.
- This circuit is also built into the new VLM1, TTL Interface Module.
Blades:
- Shutter blades – Black carbon impregnated plastic (C-PET) (5) each)
- Blade surface only can handle up to 100°C and laser power up to 50mW/mm2.
Housing Options:
- Half Housed – Optimized for cost and function, this Black anodized aluminum mount allows several mounting options.
- Full Housed – Provides a complete enclosure of the FS35. This will provide a mounting surface on both sides and two C Mount Female Threads, one each side.
- Un-Housed – Mainly for OEM applications, the device can be purchased without a mount for direct assembly into a user optical system.
- The Half and Full Housed options will provide the following standard mounting methods.
- Can be utilized in a 60mm Cage System. Rods can slide through either half or full housing to allow placement of the shutter to be adjusted or attached with 4-40 threaded holes
- T-Mount Female threaded aperture bore
- ¼-20 and M6 threaded holes included for post mounting
- Provides a flat surface for ease of mounting into an optical system
Electronic Synchronization Option Available:
- The shutter can be equipped with a sensor to provide a signal to indicate when the shutter achieves an open state. See more information under the FS35 Specification tab.
- This sensor can be omitted and is not required for shutter operation.
