74-UV small collimator

The 74-UV series collimating lenses are 5mm diamter, 10mm focal length lenses designed for coupling free-space beams to optical fibers. These lenses work well with smaller diameter fibers or for short distances such as cuvette holders.

Divergence of the beam (theta) from a fiber coupled to a lens depends on the fiber diameter (d) and the lens focal length (f).

Tangent (theta) = d/f

This 5mm lens has a 10mm focal length leading to moderate divergence angles for fibers 200um and smaller. 

External threads are 3/8-24  and these lenses fit all the standard OOI fixtures.
