Iris diaphragm

In optics there are a lot of fields where accurate amount of light, precise projection, specific depth of focus and other requirements are necessary. For such areas the use of iris diaphragms is one of the best options. Our iris diaphragms are made of high quality materials. Our iris diaphragms consist of leaves and case. Leaves are made of hardened spring steel. Stainless chrome nickel steel can be used when better resistance to heat is necessary. The surface of leaves is polished and reducing the reflections. The edges of the leaves are rounded to achieve smooth operation. For increasing the slip of leaves an invisible coating is applied. Next, protection from corrosion is guaranteed by particular polishing process. Further, for producing the case, corrosion resistant aluminum alloy is used. Fine mat black look is achieved by black-anodizing the surface of the case.
