The AGM Secutor LRF 75-640 Thermal Rifle Scope, 640×512, 75mm Lens (AGM part no. SECU75-640-LRF) is a thermal riflescope from AGM Global Vision with a 640×512 thermal sensor and a 75 mm lens. The 75 mm lens makes this the longest-reach Secutor LRF, with a narrower field of view and the highest base magnification in the line. It starts at 4x base magnification with digital zoom to 32x, and the 12-micron sensor is rated at less than 20 mK sensitivity with a 50 Hz refresh rate. It is built for long-range observation and shooting where detection distance matters more than a wide view.

Key Specifications

• The thermal sensor resolution is 640×512 at a 12-micron pixel pitch, which sets how much detail the image holds on a target.
• Base magnification is 4x with digital zoom up to 32x, so you can scan wide and then zoom in on a target.
• The objective lens is 75 mm, which sets the balance between field of view and detection range.
• The field of view is 5.9 by 4.7 degrees, or 31 by 25 feet at 100 yards, which governs how much ground you cover at a glance.
• Detection range is rated at 3,800 m/yd, the distance at which AGM says a heat signature can be picked up.
• A built-in 1,000-meter laser rangefinder gives you distance in the scope, and the page lists an integrated digital compass.
• Battery life is more than 6 hours, enough for a long night out.
• Weight is 1.55 lb, a light load on the rifle.
• The display is a 1024×768 OLED, which shows the thermal image on a crisp screen.
• It runs on four CR123A lithium batteries, a common cell that is easy to carry spare.
