Collimating Lenses

Collimating lenses are optical lenses that help to make parallel the light that enters your spectrometer setup. These lenses allow users to control the field of view, collection efficiency and spatial resolution of their setup, and to configure illumination and collection angles for sampling. Single and achromatic lenses are available.

Ocean Optics collimating lenses can be attached to the spectrometer, coupled to optical fibers or integrated into sampling accessories. Most lenses have an inner barrel threaded for SMA 905 connectors. The inner barrel slides relative to the lens fixture for adjusting the focus; a setscrew secures the barrel.
