Infrared Lenses

Appears in the issue.

New from Vicon Industries, Inc., of Hauppauge, New York, are six infrared varifocal lenses that can be used with true day/night cameras to provide sharp, focused images in daylight and at night, particularly in the presence of IR light. As these lenses provide an adjustable angle of view, from very wide to normal, they eliminate the need for trial-and-error lens fitting and for the stocking of multiple fixed-focal-length lenses to cover different viewing angles. They are designed for use on 1/3-inch CCTV cameras and can also be used on 1/4-inch format cameras. Optical construction of 10 elements in seven groups assures sharp, high-contrast images. The lenses are equipped with CS-type mounts.
