In addition to the two NIR product lines, Optec has designed and built numerous special lenses, either as modifications of standard models or as full custom designs. Optec welcomes these programs, even if the need is only for small quantities.

 

Long Focal Length NIR Lenses
For imaging at longer distances, Optec offers two lenses with Canon FD mounts and c-mount adapters. Longer focal length lenses can be built but the maximum aperture is generally subject to practical size and weight limits.

Large-Format NIR Lenses
Some newer high-resolution NIR sensors are quite large. Optec can design lenses for these.

Pictured is the C0411, a 35 mm f/1.4 lens with an image diameter of 32.8 mm and an MTF of 40% at 25 lp/mm.

Computational NIR Optics
In addition to imaging lenses, Optec can produce transfer and Fourier optics for use in optical computing. The lens shown is a relay pair designed to provide a Fourier image in the gap for filtering by a liquid crystal matrix.

Range Extenders
For convenient changes in focal length of fixed lenses, Optec supplies 2x range extenders.  Models are available for lenses with either 16 mm or 20.5 mm image diameter and all band options.
Range Extenders
C-mount Adapters
All Optec SWIR lenses are supplied with common large camera mounts to permit use of the space behind the lens for filtering.  For cameras with C mounts, Optec supplies heavy-duty adapters suitable for use with these lenses.
