LBTEK offers adjustable iris compatible with coaxial systems, featuring M4 threaded holes at the bottom of the housing. The housing includes three Ø6 mm holes for compatibility with MOP series coaxial mounting posts and incorporates flexible clamping adjustable with a 2 mm hex key.

The LBTEK 16 mm coaxial adjustable aperture is driven by a lever and compatible with 16 mm coaxial systems, allowing smooth and continuous opening and closing of the aperture. The iris aperture is housed in an ultra-thin aluminum casing with an overall thickness of 5.7 mm. It can be secured to the coaxial rod using a 2.0 mm hex key by tightening the side M4 set screw. The aperture diameter is continuously adjustable from Ø0.8 mm to Ø8.0 mm. The blades are driven by a round-headed lever, which is offset from the fourth coaxial post for convenient adjustment within the coaxial system.
