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

Fineshut SP is a light-absorbing anti-reflective sheet developed by Koyo Kogyo Co., Ltd., our predecessor. It is an ultra-thin foam polyurethane sheet, which combines excellent optical properties with an amazing thickness of roughly 0.22 mm.

Surface of Fineshut KIWAMI

Fineshut KIWAMI is a special upgrade that improves the surface shape of the Fineshut SP and further improves the anti-reflective performance. It is formed of asperities like light shielding grooves and absorbs light emitted from the direction perpendicular to the grooves.


Especially in the near infrared region, it has the best anti-reflection performance among our materials we handle, and achieved 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.

Fineshut Reflectance

※ When viewed by the naked eye, each person's perception towards "blackness" may differ            depending on the lighting environment.

The base material is fine urethane foam similar to Fineshut SP, so it retains its features such as durability and ease of handling. There are no hair loss problems specific to flocking and large reflections in the near infrared range, and even with a slight contact like plating and deposition coating, gloss is generated and performance does not deteriorate significantly.


Our Fineshut KIWAMI also complies with RoHS 2.0 regulations.

Live-Shot comparison with other Anti-reflective materials

The shutter speed of the camera and exposure setting were changed before shooting.

Here are two images taken with a normal camera and with a near-infrared camera. You can compare and confirm the stable anti-reflection performance of Fineshut KIWAMI in both settings.

  • Non reflection Black panel. (Right)

It is also recommended for use in mount adapters.

For this, we recommend applying the FineShut by using the water-pasting method. Please take a look at the video below for instructions!

Custom Cut Services Available

When we receive orders for Fineshut KIWAMI as cut parts, we propose an estimate that minimizes material costs by selecting the size with the highest material yield. Please feel free to contact us via email or contact form.


 In addition, black double-sided tape made of PET substrate is laminated as a standard specification, but we can change it to the double-sided tape you desire.

Caution on use

In order to maximize the light absorption effect by the groove shape on the surface, please make sure that the direction of the grooves are perpendicular to the light source.

There is light transmission due to microfoaming and grooves, so it can not be used for shading applications.
