功能

• The iris aperture can vary the size of the aperture without changing the center of the circle.
• In the imaging system of a lens such as a camera, it is used to change the depth of field by controlling the aperture of the lens.
• In laser experiments, it is used to pass the necessary laser beam and cut back the returning light and stray light.
• You can choose from various sizes of opening diameter according to the application.
• The adjustment lever acts as a clamp to fix the opening diameter.
• You can use the scale of the mount to adjust it to a rough aperture.
• A single iris aperture (IH) without a mount or scale is also available.
• * The aperture diameter can be changed by lightly moving the adjustment lever.
• * The adjustment lever may break if it is pushed in with strong force or applied in a different direction beyond the adjustment range.
• * Use with extreme care when handling as precision parts.
• * The iris diaphragm consists of a thin metal plate (blade).
• * If the blade is irradiated with a high power laser, it may warp due to heat and become stuck.
• * Do not use with high power laser. (CW500mW or less, pulse 30 mJ or less)
• * The scale is a rough guide.
• * There is a big back crash due to the structure of iris aperture.
• * For this reason, the diameter and scale of the iris aperture may be out of alignment.
• * Iris aperture has a very delicate mechanism.
• * Do not push or pull the wings.
