LFM Series 60 mm Cage Cube Optical Component Mount

Product Description

• Specifically designed to mount rectangular, square, or circular optical components inside 60 mm cage cubes
• For use with the BL60A stage and BL60C tilt stage
• Compatible with 60 mm cage systems

The LFM series is specifically designed to mount rectangular, square, or circular optical components inside 60 mm cage cubes. When used with the BL60A or BL60C mounting stage, the mount allows dichroic filters, filters, beam splitters, or neutral density filters to be positioned at any angle relative to the incident light.

Technical Description

(1) The LFM series filter mount is specifically designed to mount rectangular, square, or circular optical components inside 60 mm cage cubes. When used with the BL60-A or BL60C mounting stage, the mount allows dichroic filters, filters, beam splitters, or neutral density filters to be positioned at any angle relative to the incident light. The optics and filter mount should be inserted into the cage cube before being installed onto the mounting stage.

(2) The LFM2-A (new) clamps rectangular or square filters up to 63 mm in height, 30–53 mm in width, and ≤4 mm in thickness using two spring-loaded clamping arms. Apply horizontal pressure to the spring-loaded arms, insert the optical component into the resulting gap, and release to clamp. It must be used with the BL60-A fixed stage or BL60-C tilt stage for installation inside a 60 mm cage cube.

(3) The LFM2-A (old) can clamp rectangular or square filters up to 58 mm in height and 42–60 mm in length. Tighten the set screws with a wrench to secure the optic. It must be used with the BL60-A fixed stage or BL60-C tilt stage for installation inside a 60 mm cage cube.

(4) The LFM2-B features SM2 (2.035″-40) internal threads and can mount Ø2inch optical components up to 13 mm thick using the included CSK4 retaining ring. When used in a 60 mm cage cube, it centers the optical component within the cube, a feature especially important for mirror mounting. It must be used with the BL60-A fixed stage or BL60-C tilt stage for installation inside a 60 mm cage cube.
