Fixed Lens Mount, Ø1.0 in. (25.4 mm), M4 Thread, A-LINE

The A-LINE™ M-LH-1A Fixed Lens Mount is a convenient and economical solution for mounting Ø1.0 inch (25.4 mm) lenses and beamsplitters. The lens mount consists of a threaded holder with a retaining ring to hold the optic firmly, but gently. The holder incorporates an M4 threaded mounting hole for post mounting on Metric SP and MSP Series posts. The front of the holder also has a special 6 mm alignment hole, which can be used with GR Series Guide Rods for fast alignment of several A-LINE™ lens mounts. This product is also available in 10-piece saving pack .

Mounting, Aligning and Focusing Lenses Fast and Easy

A-Line™ series of self-aligning mounts are designed to make mounting, aligning and focusing lens groups fast and easy. How? The front of each lens mount has a special 6 mm alignment hole, which can be used with LH-GR Series Guide Rods such that several A-Line lens holders can be mounted together in a self-aligned row. This overview video demonstrates the easy and fast aligning process using the A-Line lens mounts.

Space Saving Design

Several A-Line self aligning optic mounts can be grouped on the same guide rod to save space. Shown are the LH-1DB with UPA-CFC fiber adapter, the LH-RMS with microscope objective and the LH-1A with lens.

Increased Stiffness for Reduced Vibration

A-Line™ lens holders are constrained both by the post/post holder as well as by the A-Line guide rod creating a "strong-box" structure that is significantly stiffer and less susceptible to vibration than individually post-mounted lenses. Shown on the right is A-line lens mounts and rods used together with TSP Series Miniature Optical Mounting Post and MSPH Series Miniature Slotted-Base Optical Post Holders.
