We Pointed A Laser Into Night Vision

Published on February 22, 2023
Duration: 20:47

This video tests the durability of an older Gen 2 night vision tube against various light sources, including lasers and direct sunlight. While room lights and flashlights caused only temporary marks, a 40mw laser and direct sunlight resulted in more significant, though not necessarily permanent, damage to this specific unit. The 'blackboxing' technique is demonstrated for recovering from temporary light damage.

Quick Summary

Lasers can damage night vision devices (NVGs). A 5mw laser caused minor issues on an older Gen 2 unit, but a 40mw laser caused immediate significant artifacts. Direct sunlight can also cause 'image burn,' potentially leading to permanent failure in modern NVGs.

Frequently Asked Questions

Can lasers damage night vision devices (NVGs)?

Yes, lasers can damage NVGs. While a 5mw laser caused only minor issues on an older Gen 2 unit, a higher-power 40mw laser caused immediate and significant artifacts, indicating potential damage. Laser safety is crucial when using NVGs.

What is the 'blackboxing' technique for NVGs?

Blackboxing is a recovery method for temporary light damage to NVG tubes. It involves placing the powered-on device in a completely dark container for 48-72 hours to allow the tube to refresh and clear any artifacts or blemishes.

Does direct sunlight damage night vision?

Direct sunlight can cause 'image burn' in night vision devices, where silhouettes of objects become temporarily visible. While an older Gen 2 tube survived several minutes, modern, more sensitive tubes would likely suffer permanent failure under similar conditions.
