Zoom lens LWIR F '= 25-225 mm F#/ 1.5

We present to your attention a zoom lens 25-225 mm with a constant F#/ = 1.5 and two movable components. The lens is designed to work in the long-wave infrared range of 8-12 microns. The image plane remains stationary over the entire focal length range.

Zoom lens MWIR F '= 15-330mm F#/ 4.0

The Opto-Technological Laboratory has developed a 15-330 mm zoom lens with an F#/ =  4.0. The lens is designed to work in the MWIR range of 3.6 - 4.9 Ám. The image plane remains stationary over the entire focal length range.

Zoom lens MWIR F '= 18-275mm F#/ 5.5

The 18-275 mm zoom lens is designed to operate in the 3.4-4.8μm range (MWIR). The lens provides focusing at a minimum distance to the object of 1 m, which is less than that of similar foreign lenses. The image plane remains stationary throughout the entire focal length range.
