Precision Light Control: This adjustable iris aperture diaphragm offers a smooth, continuous inner diameter range from 2.5 to 36mm, allowing precise control over light transmission in optical setups like microscopes, cameras, or systems for optimal image clarity.
Durable Aluminum Construction: Made of high-grade aluminum alloy, this iris diaphragm resists deformation, features no burrs or pressure points, and maintains strong elasticity and stability during repeated adjustments or long-term use in lab environments.
Wide Application Compatibility: Ideal for researchers, engineers, and hobbyists, the adjustable iris aperture diaphragm integrates seamlessly into optical benches, imaging systems, educational kits, and DIY photonics projects requiring accurate beam shaping or light regulation.
Smooth Multi-Blade Design: With 14 precision-engineered blades, the iris diaphragm creates a near-circular aperture that minimizes diffraction artifacts, ensuring clean, professional results in photography, microscopy, and scientific instrumentation applications.
Compact and Ready to Use: The package includes one 50mm OD adjustable diaphragm (6mm thick, 41g) and a protective storage box, making it easy to install, transport, or store without damage—perfect for both fieldwork and controlled laboratory settings.
