42mm Outer Diameter Iris Diaphragm

The 40-997, also known as the 42mm Outer Diameter Iris Diaphragm, is a high-quality optical component manufactured by Edmund Optics, a leading brand in the optical industry. This iris diaphragm is a type of mount accessory, specifically designed for use in optical systems to control the amount of light passing through.

The diaphragm is made of brass, a material known for its durability and resistance to corrosion. It features a circular optical shape, which is a common design for iris diaphragms due to its ability to provide uniform light control. The diaphragm has a thickness of 5.8mm, providing a sturdy base for the optical element.

The 40-997 has an outer diameter of 42.6mm, making it suitable for use in a wide range of optical systems. The minimum aperture is 1.2mm, while the maximum aperture is 25mm, offering a significant range of light control. The diaphragm features blue tempered steel leaves, which are known for their precision and durability.

This iris diaphragm is available in the metric system, aligning with international standards for optical components. The diaphragm comes with a step file (step_40997), which can be used for further design and simulation purposes. The diaphragm is currently in stock and available for purchase on the Edmund Optics website.
