Simple but Effective! Introducing the anti-reflective flock sheet
From photographer to researcher and friend to optical DIY materials, I am Teppei from Ko Pro.
We are very happy to see that our latest product, the black paint, "Musou Black" has become a hot topic recently. We apologize for the lack of stock! We would like to thank all of you for purchasing and posting even more wonderful examples on SNS. Please check it out at #musoublack on Twitter and on Instagram at #musoublack! For today, I would like to introduce another promising product, the "Anti-reflective flock sheet."
First, let me tell you something important.
Anti-reflective flock sheet is blacker than Musou Black.
You can also touch it, so the cost-performance ratio is great.
So in today's blog, we will delve into the features of the flock sheet, compare it with other companies' products, and introduce its recommended uses. Let's get to it!
Introduction to Flocking: The staple for light absorbing materials
Where there is light, there will always be shadow. Since ancient times, optical researchers have sometimes been more conscious of the existence of shadows more than light, and have been devoted to control it ...
Therefore, the anti-reflective black material is very important for both photography and optical research. Unnecessary reflection of light causes a decrease in contrast and produces noise, which impairs the accuracy and aesthetics. The purpose of an anti-reflective black material is to absorb such unnecessary light and obtain a clear image.
A standard process for making such anti-reflective materials is flocking. Above all, the process of electrostatic flocking is very effective. It is a method of adhering a fine pile to the base material while standing upright by the force of static electricity.
So the question is, why are flocked products black by the way? To that question I answer, are you familiar with the experiment involving a bundle of needles?
The shiny needles are also mysterious when viewed from the needle tip in a bundle. The content is that the tip of the needle bundle looks black. The light that enters between the needles is reflected into the bottom of the bundle many times, attenuates, and hardly returns, so it looks black. The surprising point of this experiment is that even a glittering surface of silver can produce black with repeated reflections.
A similar phenomenon occurs on the surface of hair transplants. The pile that stands upright by electrostatic flocking is like a dense bundle of needles.
Let's compare with other flocked materials
Let's understand how the structure of flocking is good for light absorption, and let's see the difference between flocking sheets. The intended use this time is a black background for photography (black background). It's a pretty specific comparison.
First up is the "Light-Absorbing Blackout Material" from Edmund Optics, a general distributor of optical parts and optical materials. They are a well-known major optical material supplier among optical designers, and they have built a product supply system that is worthy of the title, "Any optical material, available anywhere around the world!"
The light-absorbing blackout material has a surface that looks somewhat like felt. That is, the flocked hair is not standing upright, but is set randomly. It does not seem to be electrostatic flocking.
It is most likely a processing method of dropping or spraying pile on an object coated with adhesive. It is the same feeling as the Flocky painting.
The light absorption property is not the best, probably because the hair is not upright compared to electrostatic flocking. The difference is obvious when compared to our anti-reflective flock sheet with electrostatic flocking. However, the blackout material can be obtained at a low price, so the cost performance will be sufficient.
Let's compare with another flocking material-Himiron (ハイミロン)
Next we move up to a comparison of higher levels. Next we will compare a Japanese product, Himiron (black), which is a familiar material for photography by professional photographers and blackout curtains, and our non-reflective blanket.
Himiron is really a staple as a blanket for such stray light prevention, solid black background, and dark curtain use. What is the darkest thing you know? I think that there are quite a few people who respond to this question with Himiron. On the other hand, our non-reflective fleece blanket (it was called suede 0.9 for companies) was not distributed to individuals until recently, and its name recognition is zero. It was supplied to camera makers as an internal component for dark curtains and lenses.
Let's line them up side by side~
As you can see, Koyo's anti-reflective is blacker. It may be difficult to see the difference depending on the display.
But what can you tell by looking at this lining photo? Anti-reflective flock sheets are a slightly stiff rayon base material, it lacks flexibility and it is difficult to handle.
Himiron is a standard curtain, so it's really soft and supple. This is definitely suitable for shooting situations such as wrapping around shooting equipment or following unevenness of the set. Use a non-reflective flock blanket as a flat background for a simple set. I'm going to use the black material of Han.
As mentioned above, this time I have introduced a niche flocked cloth with a circle. I hope you will use it in combination with Musou Black, and use it for diorama that blends into black.
Even so, Himiron is nice to the touch. It is almost perfect for clothes, but what about our anti-reflective flock sheet? It would probably be pretty uncomfortable.
Perhaps we can make a cosplay of the shadow guy from the popular anime Detective Conan?
The truth is always one. This was Teppei from KoPro.
