Fineshut KIWAMI

反射防止 ファインシャット極

Reflectance of 1% or less in the visible to near-infrared region (250 to 2000 nm)

ファインシャット極 反射防止の溝

The Fineshut KIWAMI is an upgraded version of the fineshut SP. It improves the surface shape and the anti-reflective performance. It is formed by creating asperities like light shielding grooves. These grooves absorb light emitted from the direction perpendicular to it.

It has the highest anti-reflection performance for handling close-range infrared, and achieves a total hemispherical reflectance of 1% or less in a wide wavelength range of 250 to 2000 nm.

This amazing performance is achieved with a thinness of only 0.37 mm.

The base material is fine urethane foam similar to Fineshut SP. It retains its features such as durability and ease of handling. There is no fiber loss specific to flocking and large reflections in the close-range infrared. The glossiness and product performance do not deteriorate significantly even after plating and deposition.

It is manufactured in compliance with RoHS 2.0 regulations.

Cautions for use

  • In order to maximize the light absorption effect, use it in wherein the light source is set perpendicular to the groove of the product.
  • It cannot be used for shading applications. This is because there is light transmission (as an effect of micro-foaming and grooves).
