The E-900 series precision kinematic mirror mounts for custom laser and optical alignment employ hex drive adjusters with removable knurled knobs, and optionally available E-200 adjusters. The hand-lapped adjusters have 0.25 pitch (~100 TPI). Produced by Elliot Scientific Ltd., the mounts provide long-term stability and can be purchased in left- or right-hand versions. They offer 25-mm optic mounting (12.5 mm on request), and soft mounting for optic protection. Other features include three M6 mounting holes and a nylon-tipped stainless mounting screw.
