FINESHUT SP 0.2 / 0.4

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

It is mainly used for stray light prevention in mirror box wall surfaces of single-lens reflex cameras. We ship around 10,000 m2 each year. This is equivalent to 2.4 million single-lens reflex cameras each year when converted to mirror box applications. It is a track record of stability and reliability that can withstand mass production. Fineshut SP also complies with RoHS 2.0 regulations.

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

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.

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.

We have a laser processing machine for trial production and a single-shot punching press in our company. We support not only the supply and manufacture of base material, but we also support production of pressed components for trial production.

In addition, by sending the target parts to which you want to add the anti-reflection function, it is possible to customize a cutting design for your inquiry.

For production of large quantity, it is possible to cope with your requirements through our production network. Please feel free to contact us.
