ExtremeService^TM shutters from CVI Melles Griot offer industry-leading reliability in harsh environmental conditions. Their robust, temperature-insensitive design thrives at temperatures as low as -40°C and as high as 70°C. The coating on the blades is highly emissive in the infrared spectral region, making these shutters an ideal choice for calibrating uncooled sensors in FLIR systems. ExtremeService™ shutters provide the reliability and control needed for night-vision and infrared-illumination systems, as well as for a wide range of analytical, metrology, and photonics instrumentation.

Frequently Asked Questions (FAQs)

Question: I'm providing my own power to the OEM drive board. What are specs for the necessary power cord and power supply?

The power connector/cord we use is a Mouser Electronics #172-4201 (mouser.com / tel. 800-346-6873). Ref. Shutter Pwr Cable - Mouser 172-4201.pdf

The recommended power supply is 12VDC, regulated, 3 Amp (providing some "reserve" over the 2.5A max load).

Question: I'm using the OEM board with TTL control. What are the proper DIP switch settings?

Question: When the shutter is closed, is the transmission zero?

Question: What is the light power that can safely be incident on the closed shutter without affecting its performance?

Question: How does the X synchronization work?

Question: May I use a lower DC signal than the recommended 4X the rate solenoid voltage to open or close the shutter?

Question: What are you operational specifications for the Standard and Ultrathin Electronic Shutters?

Question: What is the laser damage threshold for the shutters blades?

*Typical
** Resistance is nominal (+/- 10%) at 20 degrees Celcius and will vary approximately 0.393% per degree Celcius
Note: Solenoid properties are nominal and apply at a 10% duty cycle as calculated by the formula: Duty Cycle (% of rated power) for a 20-msec pulse = 100×(0.32 + 0.25×hold time)/(total cycle time). To achieve specified performance, duty cycle, calculated by the preceeding formula, should not exceed 100%
