Low Mag Video Lenses
Navitar’s fixed focal length SWIR lenses are specifically designed for
SWIR (short wave infrared) cameras and applications. Lenses are avail-
able in 25mm, 35mm and 50mm focal lenghths. These lenses are ideal
for a variety of imaging applications where SWIR cameras are employed
such as perimeter surveillance, food sorting, toll-way monitoring, border
and port security, quality control or aerial imaging.
SWIR Lenses
Range Extenders
(for use with all lenses except SWIR)
The use of a range extender, installed between a lens and a
camera, will extend the focal length and increase the effective
aperture (F/number) of a video lens. For example, using the 2XE
range extender will extend the focal length by two times (2X)
and double the effective aperture of the following lens:
(2X) 50 mm, F/1.3 lens = 100 mm F/2.6
We also offer an extension tube kit, which allows you to turn
standard fixed focal length lenses into macro lenses. This kit
includes six extender tubes (0.5 mm, 1 mm, 5 mm, 10 mm, 20
mm and 40 mm) for extension from 0.5 mm to 76.5 mm. The
tube(s) mount between the camera and the lens, making it pos-
sible for you to focus a C-mount lens at a much closer distance.
Close-up Lenses
(for use with Fujinon lenses only)
Fujinon close-up lenses may be screwed to the front ring of your
lens when you need to move closer to a subject than allowed by
the minimum object distance (M.O.D.) of the lens. The Fujinon
model number of the close-up lens designates the maximum
image-to-lens distance at the telephoto end (in cm), as well as
the filter diameter of the lens.
