- Continuously Variable
- Stainless Steel Leaves for High Power Applications
The stainless steel leaves of the SM1D12SS iris allow it to be used in higher power applications than traditional spring steel irises. The aperture can be continuously varied from the maximum aperture diameter of 12 mm to a minimum aperture diameter of 0.9 mm. This iris also has internal SM1 threading on one side and external SM1 threading on the other, which makes the iris easy to integrate into an SM1 Lens Tube System. The lever-actuated diaphragm is designed to provide smooth operation for several thousand cycles. An engraved arrow indicates the position the lever must be in to close the iris.
Please note that we use a magnetic stainless steel in this iris. Due to its hardness, it offers a longer lifetime than typical non-magnetic stainless steel.Specifications
