An iris diaphragm is used to adjust an aperture without changing the center of the aperture.
Primarily used in the limited spaces of optical instruments to set an aperture size.
Application
Systems
Optics &

Coatings
◦Bare, unmounted iris diaphragms are ideal for applications where mounted irises are too large or otherwise not appropriate.
◦The IDC series has a thin body, which allows placement of optics in proximity to the front and back of the iris diaphragm.
◦Various aperture sizes are available to suit the usage.
◦The adjustment lever also functions as a clamp to fix the aperture diameter.

Attention
▶Aperture diameter can be changed by moving the adjustment lever
lightly. The adjustment lever can break if pressed with excessive
force exceeding the adjustment range, or pressed on the wrong
direction. Handle with care.
▶The iris diaphragm is a very delicate mechanism. Do not push or pull
on the blades.
▶The iris diaphragm consists of thin metal blades. Heat from highpower lasers may deform the blades and cause them to seize. Not
recommended for use with high-power lasers. (recommended max
power: CW 500mW or less, pulse 30mJ or less)
▶The iris diaphragm does not have a scale. Use the iris diaphragm
holder when a scale is needed.
