Why ordinary black is not enough
Many black materials look very dark to the eye but reflect significantly more strongly in the near-infrared. That is exactly where most current sensor systems operate: proximity sensors, Time-of-Flight cameras, LiDAR, face recognition and automotive cameras. The human eye does not see the difference – an NIR sensor does.
Applications
- LiDAR development and sensor calibration, optical tunnels and prototype housings
- Driver and occupant monitoring (DMS/OMS) test environments
- Time-of-Flight cameras, 3D cameras, robotics and gesture recognition
- Machine vision and automated optical inspection (AOI)
- NIR darkrooms, test chambers and NIR photography backgrounds
See the dedicated page: NIR-absorbing material for stray light control.
Comparing the Musou Black fabrics
- IR Flock Sheet – the only one holding reflectance ≤ 0.5 % into the near-infrared
- KIWAMI – blackest in visible light (99.905 %), but not recommended for IR use
- VL Flock Sheet – more affordable choice for visible light, no IR suppression
- Fabric FR – fire resistant, for public spaces

Honest limitations
The flocking process can generate fine fibre dust. The manufacturer advises caution where cleanliness is the highest priority or where the material goes inside precision equipment – a fibre-free alternative is often better for those cases. Creases can be treated with steam without touching the surface with an iron.
Frequently asked questions
Why choose IR Flock Sheet over KIWAMI?
KIWAMI is the blackest in visible light, but the manufacturer does not recommend it for infrared use. IR Flock Sheet keeps total reflectance at 0.5 % or less from the visible into the near-infrared, so for NIR applications it is the right choice.
Does IR Flock Sheet also work in visible light?
Yes. The same ≤ 0.5 % total reflectance covers the visible range, so the material serves both the eye and the sensor – practical when a test environment needs both.
Is an adhesive-backed version available?
Yes. Every size is available both with and without glue. The adhesive version is convenient for the internal surfaces of devices and housings.
Can the material be cut and sewn?
Yes. It can be cut, used as a cover, hung or sewn into curtain form, and it suits large areas and temporary test setups.
