OWIS IB D22 Iris 

IB D22 Iris Diaphragm

The IB D22 is an iris diaphragm with an aperture which is manually adjustable from 1.0 to 14mm. The IB D22 can be used with any SYS 40 optic holder with a 25mm aperture for fixed mounting on a pin or RT 40 slide. In conjunction with the OH 40 adjustment optic holder, the iris can be shifted by 2 mm in the XY directions.

OWIS IBM 65 Iris 

IBM 65 Motorised Iris Diaphragm

The IBM 65 is a motorised iris with an optical height of 32.5mm which is compatible with the SYS 65 rail system. The aperture can be varied from fully closed to 35mm and is available with either a 2-phase step motor with preloaded gear or with DC servomotor with encoder and preloaded gear. The IBM 65 is equiped with two limit switches to indicate the end positions (iris diaphragm open or closed).

SP 40 & SP 60 Adjustable Slits


The SP 40 & SP 60 slits have adjustable apertures of up to 7 x 7 and 12 x 12mm respectively. Both feature four, independent blades, so within the maximum aperture, any size and shape of mask can be set. To close the slits, one need only move one of the four blades. The SP 60 slit can be set to the beam height of the SYS 65 rail system using the RT 65-25-R-H slide.

W 40 Cube

W 40 cubes are useful in two or multi-dimensional set-ups together with the SYS 40 rail system. Adjustable inserts for beam splitting and deflection as well as lenses, filters and apertures can be installed. Additional adaptors are available to accomodate the W 40 cubes within the SYS 65 rail system. When mounted on a system rail S 40 with slide RT 40, the height of the optical axis is 40mm.
