Corrosion Resistant Manual Focus Iris 2.5-42mm Adjustable Aperture For Industrial Camera

• Largest Outer Diameter: This model has the biggest footprint of the series at 58mm. This makes it suitable for larger optical assemblies where significant structural support is needed.

• Thickest Build: At 6.5mm thick, it is the most robustly built model in the lineup. This added thickness enhances stability and durability, reducing vibration during precise adjustments.

• Maximum Aperture Opening: Offers the widest range of adjustment with an Enlargement Diameter spanning from 2.5mm all the way to 42mm. This allows for controlling very large beams of light.

• Extended Adjustment Rod: The control rod appears longer than the others. This design feature makes it easier to manipulate the aperture when the diaphragm is installed in deep or confined optical paths.

• Professional Photography & Videography Filters: Often used in matte boxes on film sets to control light spill and depth of field precisely.

• High-Power Laser Systems: To safely truncate or shape large-diameter laser beams without clipping or damaging the edges.

• Advanced Microscopy: For high-end research microscopes where controlling the numerical aperture precisely is crucial for resolution.

• Telescopes & Astronomy: Used as field stops or aperture masks to reduce stray light and improve image contrast in astrophotography.
