Computer Optics Inc. - 4x Infrared Zoom Lens
Computer Optics Inc. is pleased to announce its patent pending continuous zoom lens. At last, continuous zoom comes to the infrared to replace outmoded two- or three-position lenses. You are accustomed to changing the field of view with your visible video recorder, now you can get the same advantage in your infrared system.
Applications
Military: Situational awareness and detailed imagery. No dangerous image loss during the transition from wide angle to telephoto.
Commercial: News gathering with the ability to zoom in on the action. Frame shots as you would with any visible, continuous zoom lens.
Search and Rescue: Quickly scan a large area and then zoom up on areas where help is needed. See the heat before rushing into it.
