JEC Adjustable Iris Sacrificial Lens – Control the Light. Protect the Tube.

Why choose between protection and performance when you can have both?

The JEC Adjustable Iris Sacrificial Lens combines a rugged sacrificial lens with a fully adjustable iris aperture, giving you greater control over incoming light while protecting your valuable night vision device from scratches, debris, and impacts.

Featuring an adjustable aperture range from 1.5mm to 22mm, the iris allows users to fine-tune image brightness and increase depth of field in changing lighting conditions. Unlike a traditional lens cap, the iris lets you quickly adapt without removing equipment, making it ideal for training, navigation, and daylight function checks.

Compatible with PVS-14, PVS-7, AVS-9, and BDNV-1431 devices using the standard LIF thread, it can be used as a standalone solution or alongside a lens cap for maximum flexibility.
