Musou Black IR Flock Sheet – black fabric for infrared light absorption
Black that works where the eye cannot see. Musou Black IR Flock Sheet is an electrostatically flocked rayon material developed to reduce reflections and stray light in the visible and near-infrared (NIR) range – for LiDAR development, machine vision, sensor calibration and optical test environments.IR Flock Sheet in brief Total reflectance ≤ 0.5 % from visible to near-infrared (AOI 8°) – absorption ≥ 99.5 % across the range Material: rayon base fabric + electrostatically flocked rayon pile, carbon-containing fibres Thickness 0.9 mm ± 0.2 mm Sizes: A4 sheet or roll 950 mm wide, 0.5–20 m Available with adhesive backing or without glue Processing: can be cut, hung or sewn into curtain form Ordering and priceMade to order – price and lead time on request.

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 See the full fabric range or the Musou Black world.Honest limitationsThe 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 questionsWhy 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.Documents Safety data sheet (SDS, EN) RoHS test report (PDF) Questions: get in touch – we serve companies, research institutes and universities with quotes and invoicing.
