Product Overview

An 8MP 4K fisheye lens with a 650nm IR-cut filter, designed for immersive imaging applications with up to 1/2″ sensors.

The DSL618A-650-F1.8 is an 8MP fisheye lens designed for 4K hybrid systems with up to 1/2" sensors. Featuring a 185-degree field of view and tailored distortion, this lens provides exceptional image capture for immersive video applications. The 1.8mm effective focal length and fast F/1.8 aperture ensure bright, sharp images even in low-light conditions. With its 650nm IR-cut filter, the lens offers precise color reproduction, making it ideal for security, automotive, and surveillance systems. The M12 x 0.5mm thread and compact design ensure easy integration into camera systems. This fisheye lens is constructed with multi-layer anti-reflective coatings to enhance light transmission and minimize flare or ghosting, resulting in crisp and high-contrast images. The lens's durability and high optical performance are supported by an aluminum housing and precision-ground glass optics, making it suitable for both indoor and outdoor use.
