Sale price$771

Description

The 84-UV-25 collimating lens is designed for coupling larger free-space beams to optical fibers. These large-diameter lenses are especially suitable for collimating light at long distances in open air and have been tested to distances of up to 40 feet.

Collimating lenses are common to most of the sampling accessories we offer, and are used for an extensive array of applications and measurement techniques including absorbance, irradiance and emission.

Versatile – lenses optimized for the UV-Vis (185-2500 nm)

Rugged – stainless steel barrel with black oxide finish

Long focal length – adjustable up to 100 mm
