IMS-7-1

The Motorized Optical Iris Diaphragm is a mechanical device used to control the amount of transmitted light through an adjustable aperture.

The shape of the circular optical aperture is not perfect circular because it is achieved using a number of thin and smooth curved blades or leaves.

These blades are attached at one end to a ring which when rotated changes the diameter of the rezulting aperture.

Zero Aperture or fully closable iris diaphragms are a special category. They consist of 2 parallel planes of blades which can fully obstruct the light.

Regular irises do not fully close but can achieve up to a minimum aperture of 0.5 mm diameter.

Applications for Motorized irises include cameras, microscopes and other scientific instruments or apparatus where it limits the amount of light reaching a specimen, a sensor or photo-detector.

The IMS-7-1 motorized optical iris diaphragm allows continuous and smooth adjustment of the circular aperture from a computer or another electronic programmable machine.
