“SUGO-KURO” Black Plating
“Sugo-Kuro” is a black plating film that suppresses light reflection through a complex surface profile, resulting in a reflectance of less than 1% on the visible light spectrum (380-750nm). It prevents stray light from entering and scattering in optical instruments such as cameras and spectrophotometers, reducing image noise and measurement errors.
Special Features
Less than 1% reflectance (visible light spectrum)
Low reflectivity is achieved thanks to the special surface’s suppression of light reflection.

Surface morphology
Blackening Mechanism
Thin film (approx. 3 μm)
Thanks to its thinness (approx. 3µm), Sugo-Kuro is ideal for products for which dimensional accuracy is required.
Excellent heat and ultraviolet resistance
Black paint and black anodized aluminum with an organic paint will fade or discolor from heat and ultraviolet rays. Our black plating is extremely durable thanks to its inorganic coating. It can withstand a temperature of 300℃.
Prevention of outgas
In a vacuum environment, such as outer space, organic paint may generate outgas, which may cause corrosion of the perhipheral parts and the fogging of lenses. Our black plating is able to prevent the occurrence of outgas, due to not using an organic coating.
RoHS Compliance
In compliance with the RoHS directive, Sugo-Kuro does not contain hexavalent chromium, unlike conventional blackening. Sugo-Kuro can be applied to European products.
Application Examples
Digital cameras
Security cameras
Projectors
