VS35 35mm Optical Shutter

→ 상품 상세 정보 : VS35 35mm Optical Shutter

Overview

The Uniblitz VS35 has been designed to provide accurate, repeatable exposures for a wide variety of applications. The VS series shutters have been successfully field tested in microscopy, video imaging, PMT protection, and photographic applications worldwide. The VS35 is available in a housed or un-housed configuration for OEM applications (or simply where spatial limitations are a consideration).

Uni-stable shutter devices, like the VS35, require power to hold the blades in the open state (though the device can be custom-configured for “normally open” operation).

Specifications

For additional technical information please see the VS35 Optical Shutter Datasheet.

1 Voltage level required across actuator coil when being held in the open position.
2 Dual hold voltage system included in the VCM-D1 Driver.
3 (Continuous/Burst) Continuous frequency rating specified at shutter’s minimum exposure pulse. Burst frequency rating specified for four (4) seconds maximum with one (1) minute minimum between bursts.

Electronic Synchronization System

The Electronic Synchronization System provides a feedback signal (through the driver utilized) after the shutter transfers to the open state. The system incorporates an infrared emitting diode, an infrared sensitive detecting transistor, and an interrupting vane. The vane is attached to the shutter so as to block the light path between the emitter and detector in the closed position. When the shutter transfers to the 80% open position, the vane is removed from the infrared light path, allowing the emitter to switch the detector to the active state. No connection to the designated synchronization pins when no electronic sync. is selected.

Shutter Timing

---

The question regarding enhancement of shutter speed with the application of user supplied lubricants has been repeatedly asked. It is our experience that lubricating the shutter blades will actually slow the shutter down and eventually render the shutter inoperable. Under no circumstances should any type of lubricant be applied to the shutter blade area.
