Iris Calculator enables you to instantly determine the feasibility of an iris diaphragm design. By eliminating all the work involved in creating CAD or vector drawings of the mechanism, you can alter and refine your design on the fly - safe in the knowledge that each iteration will function perfectly.
Dimensions for the blade array geometry, actuator ring, and housing are all calculated in software from the the initial dimensions you specify - along with minimum and maximum apertures - allowing you to review your design and components with ease.
Simply enter any dimensions you know and the rest will be calculated for you!
Rapidly assess design solutions, then export the iris template for use in your CAD or vector application. React quicker, and more efficiently when designing custom-sized iris diaphragms.
An iris diaphragm is a mechanical device, that typically regulates the passage of light passed through a lens, in an optical system. This is achieved by blocking excess light, allowing only a regulated amount through a controlled aperture mechanism.
An iris functions by use of an array of movable blades or leaves. These are hinged at one end and sweep in unison, providing a smooth and adjustable aperture.
Irises can either be actuated by moving a lever, or by use of a motorised gear arrangement.
Irises can be found in all sorts of applications such as; cameras, microscopes, and theatrical spotlights - to name just a few!
Learn a little about how iris diaphragms work, and the different ways they can be used.
