[Highly-functional Material Week TOKYO 2021] IR ink for infrared cameras - Seiko Advance Co., Ltd.

Nice to meet you. My name is Suzuki from Seiko Advance. This is our recommended product.
I will explain the ink for infrared cameras and IR ink.

There are four major features.
One is low transmission of wavelengths up to infrared light,

As you can see from this graph, it is as low as 780 nanometers.

Transparency can be suppressed, but it rises sharply from 780 nanometers,

After that, it can have a transmittance of 90%.
Next, there is a high degree of blackness.

Here, with conventional IR ink, high blackness could not be maintained, but
As you can see here, the blackness can be expressed compared to the past.

The third is that this is a pigment ink, so it has high light resistance.

This is a fade meter test, 400 hours

⊿E can be suppressed to 1% or less.
Finally, because of the low HAZE value, the haze value at 940 nm is 1% or less.

We are able to maintain a fairly low HAZE value.

It’s at the bottom of this panel, but the HAZE value of the IR of the conventional product is

It’s pretty hazy, but TCIE and ATS here

It is a product that allows you to take a fairly clear image with a camera.
This is a product that we have developed in anticipation of future autonomous driving of automobiles.

We will continue to publicize and use it for our customers.
I would like to proceed.
