Specialised Infrared Cold Mirror Filters

These 2-pack filters are built for Hero4, YI 4K, YI 4K+ and RX0 cameras. They strip away all visible light so only infrared reaches the sensor, opening up creative effects and night-vision work with an IR illuminator. Photographers using Back-Bone modified cameras gain a practical route to full-spectrum imaging.

Passive Optical Components

The filters are passive glass elements that draw no power and generate no heat or noise. They mount directly on the lens thread, adding negligible weight and requiring no batteries, cables or cooling. Normal camera operation and battery life are unaffected.

Lens-Thread Mounting for Creative IR Work

Each filter screws onto the front of a compatible lens, so the camera needs a matching filter thread or an adapter ring. They free the shooter from focus shift between visible and infrared light when used with IR-corrected optics. Builders needing autofocus assist beams or standard colour photography will find these filters unsuitable.

Questions about this item

How do I install the Back-Bone Infrared Cold Mirror Filter on my Hero4 or YI 4K, and what step do people get wrong?

Screw the filter onto the lens threads of your Hero4, YI 4K/4K+, or RX0; the common mistake is using a standard lens instead of an IR-corrected or Day & Night lens, which causes soft focus because infrared light focuses at a different plane than visible light.

What maintenance or replacement will these filters need over time?

The glass filters have no consumable parts; keep them clean with a microfibre cloth and lens solution, and replace only if the coating is scratched or the filter ring is damaged.

What limit appears first when using these filters continuously for night vision?

The filters block all visible light, so the scene is entirely dependent on infrared illumination; the practical limit is the range and power of your IR illuminator, not the filters themselves.
