TECHSPEC® Small Optic Mounts are ideal for mounting 1 - 8mm diameter lenses. The clamps can be mounted horizontally, where the optical centerline is on a 25.4mm offset from the mounting centerline, or mounted vertically, where the optical centerline is 44mm higher than the post-mounting flat surface. TECHSPEC® Small Optic Mounts feature a spring-loaded construction that ensures secure mounting of small diameter lenses regardless of orientation. The mounting clamp width (2mm for #12-869, 3.5mm for #13-800) is thin enough to allow two short focal length lenses to be placed directly next to each other. These mounts include ¼-20 TPI threads for post mounting and can be adapted to metric posts with adapter #53-928 to easily integrate into any bench-top system.
