The ATN IR Spot/Flood Lens fits over the PVS7's integral IR illuminator. By turning the spot/flood lens, the operator can adjust the IR illumination from wide and diffuse to narrow and concentrated. The spot-focus feature is particularly useful when using high-power accessory lenses, while the wider beam is well suited for general-viewing applications.
Typically, the PVS7's IR unit produces a 40deg. beam with a range of approximately 50'/15 m. The Spot-Flood Lens narrows the beam to 20deg., which typically provides visibility to 150'/50 m.
