• Large-Sized Industrial Design: With an outer diameter of 50mm​ and a thickness of 6mm, this model is designed for larger optical systems. Its size makes it suitable for applications requiring significant aperture control and stability.

• Broad Aperture Adjustment Range: Offers an Enlargement Diameter​ range from 1.5mm to 36mm, allowing for versatile control over a wide spectrum of light beam sizes, from narrow to very wide.

• Secure Multi-Point Mounting: Features multiple mounting holes evenly spaced around the perimeter, ensuring a stable and accurately aligned installation in various optical instruments.

• Robust Manual Adjustment Mechanism: Includes a metal rod actuator, allowing for smooth and precise manual adjustment of the aperture blades, enabling quick and easy modification of the aperture size.

• Microscope Illumination & Focusing:​

  The large outer diameter (56mm) and wide aperture range (1.5-36mm) make it ideal for positioning in the condenser or as an aperture stop in compound microscopes. It allows precise control over the numerical aperture and the intensity of light illuminating a specimen, which is critical for achieving high-resolution images.

• Laser Beam Shaping & Diameter Control:​

  In laser-based industrial or research applications, this diaphragm can be used to "crop" or define the beam diameter. The sturdy construction and smooth manual adjustment help in fine-tuning the beam size to match the requirements of downstream optical components, preventing overheating or damage.

• Imaging Systems in Harsh Environments:​

  The robust design (thicker at 6mm and larger diameter) suggests it can withstand more demanding conditions. It can be used in industrial imaging systems, such as machine vision cameras used in manufacturing inspection, where precise light control is necessary to capture clear images of products.
