Design Features


Sci-in Tech shutters offer precision exposures with computer control for the lab or observatories. Engineered for longevity, low temperature and consistancy.

Large Aperture
 The PS-250 is typically used for single large area CCD's while the PS-500 and larger shutters are matched with mosaic CCD assemblies.
Square Aperture
 Square, not round, is the perfect match for CCD's since their shape is square or rectangular. This eliminates corner vignetting, a requirment for most scientific imaging.
Small Footprint Size
 The core of this design is minimal weight for given aperture size and small footprint area to minimize possible mechanical interference.
Computer Controlled
 RS-232 with contact-closure and opto-isolator offers options to choose.
Low Power Consumption
 External power supply allows remote location of a heat source. Motor power is consumed only when blades are in motion.
Precision Timing
 An internal clock allows poling to 0.1ms.
Superior Shutter Blade Strength
 Sci-in Tech has used carbon-fiber shutter blades since 1996 to protect expensive CCD arrays from possible objects contacting a vacuum window.
Tier Stepped Aperture Port
 Reduces scattered light and allows a mask, filter or window to to be set in below the shutter surface in special situations.
Completely Serviceable
 At 2.5 to 3 million cycles, a rebuild replacing all moving parts can be done.
Long Life
 Rejuvinating to new condition allows many years of operation, reduces waste and is cost effictive.
Can be adapted to operate in Vacuum
 Vacuum compatable components can be used for vacuum service as a special order.
Special Sizes are Available
 Sci-in Tech standard shutters increase in increments of 2.500". Special size apertures including rectanglar, are offered as a custom design, with a NRE charge included.
