Streamline your iris diaphragm design process with intuitive software.
Design and make an iris diaphragm, effortlessly!
1 year access to our online design software tool, for helping design and make mechanical iris diaphragm apertures quickly and precisely.
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!
Features Rapidly assess design solutions, then export the DXF iris template for use in your CAD or vector application. React quicker, and more efficiently when designing custom-sized iris diaphragms.

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
