Fineshut SP 0.2 & 0.4 Ultrablack sheet

In stock, ready to ship!

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 (0,12 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.
