Optical Lens for Thermal Night Vision

 

Product description - DT-ONX4

The DT-ONX4 is a high-performance optical lens engineered specifically to maximize the effectiveness of night vision image intensifier systems in near-total darkness. Its design is singularly focused on gathering the maximum amount of available light and delivering it with exceptional clarity to the intensifier tube, transforming severely low-light scenarios into actionable, detailed imagery.

At the core of its performance is an exceptionally wide F1.45 aperture. This large aperture is strategically paired with a 4X optical magnification, allowing the lens to capture significantly more ambient light than conventional designs. This results in a markedly brighter and higher-contrast image for the user, reducing scene noise and enhancing detail recognition when illumination is minimal.

Optical excellence is further ensured through advanced engineering that prioritizes high center Modulation Transfer Function (MTF) and minimal distortion. This precise calibration guarantees that the captured light is transmitted faithfully, enabling the coupled image intensifier to produce a sharp, clear, and usable picture with accurate spatial relationships across the entire field of view.

The lens features a defined 5° to 10° field of view at its 4X magnification. This relatively narrow perspective is a deliberate optical choice, favoring greater detail resolution and extended identification range over wide-area scanning. It is ideally suited for focused long-range observation, surveillance, and detailed target assessment tasks.

Built for field reliability, the DT-ONX4 is housed in a rugged construction capable of withstanding shock, vibration, and extreme temperatures. Its operational range of -50°C to +80°C ensures consistent optical performance and integrity in the most demanding environmental conditions, from frozen landscapes to arid deserts. This robust design protects the critical lens-to-intensifier alignment, guaranteeing that superior image quality is maintained not only in controlled settings but through the rigors of real-world deployment.
