Optical Lens Holders, Fixtures and Mounts
Ocean Optics offers optical lens holders, fixtures and mounts for manipulating collimating lenses in various measurement setups. Holders position lenses and can be adjusted to accommodate various samples. Optical post mounts allow users to position lenses on optical breadboards.
74-ACH
Adjustable collimating lens holder
OPM-SMA
Optical post for mounting lens fixtures to breadboards
The 74-ACH is an adjustable collimating lens holder. It’s a versatile assembly designed for mounting lenses at multiple positions, both vertically and horizontally. This makes it particularly useful for transmission measurements of large or thick samples.
The OPM-SMA is a fixture for mounting 74-Series Collimating Lenses and SMA 905-terminated optical fibers. The OPM-SMA consists of a 1.5-inch OD disk with 3/8-24 threads for use with lenses and an adapter for use with SMA 905-terminated optical fibers. A special adapter that holds an SMA 905-terminated optical fiber flush against one surface of the OPM-SMA is included. The OPM-SMA also includes 8-32 (Imperial) and M6 (metric) threads for attachment to an optical post.
