UniqueFire 850nm IR Illuminator Flashlight Lights for Night Vision,Fresnel Lens Zoomable Infrared Torch Light Rechargeable,Rapid Focus & Dimmer Switch,Exquisite Black Box Packaging Max Lighting 1000M - UF-2001D

• 【Fresnel Lens ir light】IR Flashlight Uses Fresnel Lens Zoomable Focusing Technology,Utilize the short focal length microstructured Fresnel optics which can be more focused,The light penetrates more strongly, fresnel lens is thinner than the ordinary lens can shine much farther than,After focusing by rotating the head, the Fresnel lens cooperates with Vcsel 850nm lamp beads, and the maximum illumination distance can reach 1000 meters. 【Vcsel 850NM Chip Module】IR Module utilizes the most advanced Vcsel IR BLACK LED with the latest chip technology, high efficiency, low thermal resistance,Emits infrared light with 850nm wavelength,produce a powerful punch with approximately 500-1000 meters range (approx. 1000 yards) with focused beam. With the latest chip technology, Fresnel Lens and an excellent package, lifetimes of up to 50,000 hours are easily obtainable. 【Rapid Focus & Dimmer Switch Technology】 Features Upgraded UF-2002D ir spotlight Rapid Focus and Dimmer Switch features to fine-tune the beam. Compared with ordinary push-type gear switches, the operation is more flexible and convenient, and the brightness of the torch can also be adjusted more accurately.When the light is on, turn the tail switch to adjust the brightness of the light from 5% to 100%(Note:If the brightness keep, it means The brightness has reached the lowest or highest) 【Zoomable with Adjustable Focus】ir flashlight adjustable Lens rotary focusing function enable the ability to focus in for a tight ir spot light or back out for a ir scope light, especially designed for long range illuminations. can illuminate much farther with focused beam, compared with illuminator without focusing functions. 【Material quality】 The fuselage is made of aircraft aluminum alloy Very sturdy enough to shatter glass in a crisis,Housing Diameter: 1" (25.4mm). Fits any 1" (25.4mm) ring and mount. With an O-ring seal, it is very effective against water and dust, and can be used in rainy days.
