→ 상품 상세 정보 : NS65B 65mm Optical Shutter
Overview
The Uniblitz NS65B is a 65mm-aperture bi-stable optical shutter utilizing our patented N-CAS® technology. The NS65B’s simple design provides maximum clearance around the aperture, and a machined flat surface makes for its easy integration into telescopes, video cameras, etc. The NS65B has an overall diameter of 5.15 inches, and an electronic synchronization is available (by special order).
Bi-stable shutter devices, like the NS65B, require no power to hold the blades in either the open or closed state.
Specifications
For additional technical information please see the NS65B Optical Shutter Datasheet.
| Coil Resistance | Pulse Voltage to Open | Hold Voltage |
|---|---|---|
| 12 OHMS 1 | +36 VDC 2 | N/A |
| Weight | Operating Temp. | Max. Opening Bounce | Max. Closing Bounce | Max. Freq. of Operation 3 | Number of Shutter Blades |
|---|---|---|---|---|---|
| 4.94 oz (0.14 kg) | 10 – 50 °C | 15% | 5% | 1.0 Hz / 3.0 Hz | 6 |
1 Two 24 OHM coils wired in parallel
2 Peak voltage as provided by the VED24 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
Presently, the NS65B does not include a synchronization system as a standard option. Pins 3, 4, and 5 have no connections at this time. The synchronization feature may be available by special order if it is required for your application. Please contact us to discuss your request in further detail.
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.
