Dimming and Shutters
GSI provides wide angle, achromatic analog and digital light control.
The GSI dimmer is an optomechanical device providing 10 stops of light control while maintaining excellent brightness and color uniformity over a wide angle. These devices solve the problems associated with conventional Variable Neutral Density filters.
The GSI Digital Neutral Density shutter is a polarization based switch providing up to 7 stops of light control in 1 stop increments with brightness and color uniformity. This device provides videographers and photographers independent control of exposure without having to adjust aperture or frame exposure.
