The CHAD Iris | Cold Harbour Supply The CHAD Iris | Cold Harbour Supply
All In Focus
If you’ve used night vision for long, you’ll know the frustration: focus on the distance and anything close up, like a map, your kit or the ground at your feet, turns to a blur. Refocusing the objective every time is fiddly, especially on an articulating binocular or in adverse conditions.The CHAD Iris solves that with an adjustable iris that screws onto your objective lens. Close it down slightly and your depth of field opens up, so near and far stay sharp together without re-adjusting the main lens. Open it fully and it sits clear of your lens, with no loss of image.
It’s useful in bright conditions too. Closing the iris cuts the light reaching the tube, giving auto-gain devices a form of manual brightness control and reducing bloom around streetlights and other bright sources. Fully closed, it works like a pinhole day cap, so you can leave it fitted. For long-term storage or extended exposure to light, still use a proper lens cap.
The front lens also protects your iris and objective from dust, debris and impacts.

NOODL Lanyard Retention | Cold Harbor Supply NOODL Lanyard Retention | Cold Harbor Supply
Simple Insurance For Your System
Night vision is expensive, and helmet mounts can and do let go. The NOODL (Night Observation & Operations Device Lanyard) is a simple, low-cost backup that keeps your device tethered to your helmet. It holds it steady while deployed and stops it hitting the ground if it ever comes free.
Unlike Velcro straps that snag on branches and brush, the NOODL attaches directly to a helmet hard point. A Cordura loop goes under your front helmet bolt, and an adjustable shock cord clips to your device. Installation takes a few minutes, and once it’s set up you’ll barely notice it’s there.
What’s new in V2
- Cordura loop by Macabre Solutions for the front helmet bolt
- Lower-profile, easier installation
- Configurable for any helmet attachment point
KEY FEATURES
- Keeps your device secure and steady when deployed
- Adjustable shock cord tension
- Fits most helmets via the front ARC rail bolt
- No Velcro to snag on vegetation
- Everything you need to install is included
IN THE BOX: 1× 12" elastic shock cord, 1× 0.6" black-oxide split ring, 1× 1/8" mini carabiner, 1× Multicam Cordura tether loop (Macabre Solutions), and 2× heat-shrink pieces.
Note: single-point retention. For full tension, use two. Not recommended for airborne or high-angle use.

Light Interference Filter Light Interference Filter
Light Interference Filter
£75.00Your Tube’s First Line Of Defence
Bright green lasers can damage an image intensifier tube in an instant. Tube damage from light exposure isn’t covered by warranty, so prevention matters. The LIF is a mil-spec filter that screws onto your objective lens and helps protect your device from high-power green lasers and similar wavelengths.
It also works as a very low-profile cover, keeping dust, debris and minor knocks off your objective in everyday use, without adding bulk or getting in the way of focusing.
KEY FEATURES
- Helps protect against high-power green lasers and similar wavelengths
- Very low profile; doesn’t interfere with focus travel
- Shields the objective from dust, debris and minor impacts
- Screws straight onto PVS-14 style objective lenses
COMPATIBILITY: Fits devices using US mil-spec PVS-14 objective lenses. Tested with Noctis (Fujinon and Qioptiq), Salvo Engineering, Optronics, Photonis Boomslang and RPO 2.0 and 3.0.
Objective lens only; not for use on the eyepiece. A filter reduces laser risk but can’t guarantee protection from every source. Never point your device at a laser on purpose.
- Helps protect against high-power green lasers and similar wavelengths
