  • FINESP02-25

Fineshut SP is a light-absorbing anti-reflective sheet that uses ultra-fine foam polyurethane sheet, which combines excellent optical properties with an amazing thinness.

This sheet has a thickness of ~0,2 mm or ~0,4 mm. You can choose between the standard double adhesive tape (Type DIC#8103D; 0,15 mm) or the thinner double adhesive tape (Type DIC#8616UJ; 0,05 mm) on the back attached or without the adhesive tape.


Why Fineshut?

  • NO fiver loss or fiber falling problem in flocking treatment! Can be used next to the camera sensor!
  • Provides a stable light absorption effect from visible light to infrared light!

It is mainly used for stray light prevention in mirror box wall surfaces of single-lens reflex cameras. It complies with RoHS 2.0 regulations.


Stable light absorption performance from visible light to infrared

Black nylon flocking treatment is a common material for anti-reflection treatment which exhibits a high light absorption effect in the visible light range, but has the disadvantage of reflecting light as it approaches the near infrared range. Fineshut SP can provide a stable light absorption effect from visible light to infrared light.


Mechanism of light absorption (Microporous Surface)


The photograph is an image of the surface of Fineshut which is observed with an electron microscope. The surface has a microporous structure enabling light to be absorbed by entering the uneven structure. The material is polyurethane which is highly durable and easy to handle. There is neither fiber loss nor fiber falling which is a problem in flocking treatment.


* When viewed by the naked eye, each person's perception of "blackness" may differ depending on the lighting environment and other conditions. 


Total reflectance values of our materials are based on the industry-standard AOI 8° index. Total reflectance is the measurement result of combining both diffuse reflection and specular reflection measurements. AOI 8° means that the light is incident at an angle of 8° from the normal. 

For example, based on this index, our "Foam" series consistently absorbs light from ultraviolet to near-infrared light ranges. This performance is achieved by the uneven structure derived from the foaming process and the composition of carbon atoms blended into the resin. 

We also offer a variety of fabrics. Our entry-level “VL Flock Sheet” is cost-effective and provides strong light-absorption performance in the visible light range. In contrast, our “IR Flock Sheet” provides improved ultraviolet and excellent infrared light-absorption performance, which are the weak points of the entry-level VL Flock Sheet. Our premium fabrics, Musou Black Fabric FR and Musou Black Fabric KIWAMI, are our blackest products and have the best visible-light absorbing performances. The FR variant is treated to be fire-resistant and is great for indoor use. Meanwhile, our flagship, Musou Black Fabric KIWAMI, is the World’s Blackest Fabric in the visible-light range. 

Musou Black Paint's light-absorption performance will vary depending on the painting method, so please keep that in mind when applying. For best results, please apply with an air-brush.
