Mechanical Iris Diaphragm Aperture 352mm Compact, precise, and durable adjustable aperture for optical and imaging systems. This mechanical iris offers smooth control over light and beam diameter, with reliable longterm performance for laboratory, industrial, and photographic applications. Key features and benefits Adjustable range: minimum aperture 3 mm, maximum aperture 52 mm for accurate control of light, depth of field, and beam size. Precise 14blade design: provides a more circular aperture shape at intermediate settings, improving uniformity of illumination and image quality. Clear dimensional fit: outside diameter 73 mm, inside diameter 52 mm, thickness 8 mm for straightforward integration into optical assemblies with matching dimensions. Durable construction: made from quality materials for stable performance and long service life under repeated adjustment. Easy integration and control: mechanical operation enables smooth, repeatable aperture changes without power or electronics. Technical specifications Product name: 352mm Mechanical Iris Diaphragm Aperture Outside diameter: 73 mm Inside diameter: 52 mm Thickness: 8 mm Minimum aperture diameter: 3 mm Maximum aperture diameter: 52 mm Diaphragm blades quantity: 14 pieces Material: quality, durable construction for stable operation Practical use scenarios Optical labs and prototyping: integrate into bench optical setups to control beam diameter and reduce stray light during experiments and demonstrations. Imaging and machine vision: mount in front of lenses or cameras to adjust aperture for exposure, contrast, and depth of field in inspection and vision systems. Projection and illumination: use in projectors, microscopes, or illumination modules to shape light output and fine tune brightness and uniformity. Why choose this diaphragm Delivers reliable, repeatable aperture control for precise optical tuning. Robust construction supports frequent adjustments and longterm use. Standardized dimensions simplify mechanical integration into custom housings and optical systems. Installation tips Verify matching inner or outer mounting dimensions before assembly. Ensure the iris is secured in a stable holder to maintain alignment and repeatability. Clean blades carefully with a soft brush or compressed air to avoid introducing particulates that could affect performance. This mechanical iris diaphragm is a straightforward, durable solution for applications that require controlled, adjustable apertures between 3 mm and 52 mm with consistent performance over time.
