Long-Range Night Vision with an Infrared Laser
A new long-range night vision device utilizes an infrared laser to illuminate scenes, allowing for greater visibility at extended distances. The device, developed by Project 326, faced challenges in selecting a suitable laser but ultimately succeeded with a Vertical-Cavity Surface-Emitting Laser. Despite some limitations due to atmospheric conditions, the setup demonstrated the ability to capture images at distances of up to 650 meters.
- ▪Most consumer-grade night vision devices rely on near infrared light sources that are not visible to the human eye.
- ▪Project 326's device uses an infrared laser to achieve long-range visibility, overcoming limitations of traditional night vision.
- ▪The final laser used was a VSEL diode array element, which was safe for long-range use but could burn materials at close range.

Long-Range Night Vision With An Infrared Laser No comments by: Aaron Beckendorf May 18, 2026 Title: Copy Short Link: Copy Most consumer-grade night vision devices are basically a standard camera without the usual filter to block near infrared (NIR) light, which are then paired with a NIR light source that’s not visible to the human eye. Unlike the passive night vision provided by a photomultiplier tube, these can’t resolve objects beyond the beam of their illumination source. On the other hand, if, as [Project 326] did, you use an infrared laser to illuminate the scene, you can still get a very long range out of these devices.
