Sale price$310

Description

Collimating lenses are curved 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.

Each 74-series lens is 5 mm in diameter, has focal length of 10 mm and is responsive at UV-VIS or VIS-NIR wavelengths. The achromatic lens option (74-ACR) corrects for spherical and chromatic aberrations.

Versatile – lenses optimized for the UV-Visible (185-2500 nm) or Visible-NIR (350-2500 nm)

Rugged – stainless steel barrel with black oxide finish

Fiber optic – couple to optical fibers or spectrometers

Adjustable – position lenses for converging to diverging FOV (~25°)
