Fixed Lens Mount, 3.0 in. (76.2 mm), 8-32 Thread, A-LINE

The A-LINE™ LH-3A Fixed Lens Mount is a convenient and economical solution for mounting Ø3 in. (76.2 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 8-32 threaded mounting hole for post mounting on English SP and MSP Series posts. The front of the holder also has a special Ø6 mm alignment hole, which can be used with GR Series Guide Rods for fast alignment of several A-LINE™ lens mounts.
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.
