Background
Now, various nondestructive analyzers using optical systems have been commercialized, and are applied to the application of R & D and production lines. However, many have been limited to analyses in a range of wavelength bands or in some wavelength bands.
In this technology, we proposed a “multispectral camera” which can visualize and visualize properties in physical properties by selecting and analyzing the difference of reflection spectrum by selecting the (6 wavelength) band over a wide wavelength band.
Technical Content
The images of digital cameras represent color images of 1 pixel with 3 colors of RGB (red, green, blue).
In contrast, an image shot with a hyper-spectral camera is an optical measuring instrument that can capture the color (= light spectrum) from visible to near-infrared (= 141 bands) in a unit of 141 (=). 1.
In other words, because the 1 pixel has an independent spectrometer of about 141 bands, the object can not only determine the object’s shape, but also the physical properties of the object in the pixel. That is, it can be said to be a next-generation optical measuring instrument capable of analyzing the state recognition of the object’s identity and the activity of the object. The function of a hyper-spectral camera enables ordinary people to see phenomena that are invisible to ordinary people, such as freshness of vegetables and eyes of craftsmen.
This product has the same principle as a hyper spectrum camera, but it is a multi-spectrum with a wavelength band of 6 bands.
(You can expand to 8 6 bands with RGB)
■The filter using the filter filters through the specific light is used.
■You can switch the filter (measured wavelength) on the rotary wheel.
■You select the mounting filter (measured wavelength).
■Filter uses 25 mm diameter commonly used in the research field.
■There is no need to prepare the objective lens. (The objective lens is built-in.)
■Size is 177 mm x 10 mm x 100 mm.

Strengths of technologies and know-how (novelty, superiority, utility)
[Comparison with other multispectral cameras]
1)Made in Japan
– Many of the multi-spectral cameras are made in abroad and expensive.
This product is manufactured in Japan and is cheaper than overseas.
As described later, we provide flexible services to meet your needs.
2) Wavelength selection function
– Many multispectral cameras measure only the already determined wavelengths.
The multi-spectral camera allows the user to choose a desired wavelength band only by changing the filter. Therefore, it is easy to analyze applications suitable for applications.
Comparison with Hyperspectral Camera
The hyperspectral camera (manufactured by our company) is a 141 band range, with a wide range of applications that can be analyzed. As the multispectral camera is a band of 6 bands (9 bands by customization), the application can be analyzed, but it is inexpensive because its structure is simple. You can choose them depending on your application.
[Service ]
- Shooting test patterns
If a multi-spectral camera is requested prior to the introduction or lease of a device we can take the test pattern.
※ Unless the purpose of shooting is unclear.
2) Custom customization
The development know-how of multispectral camera hyperspectral cameras.
Therefore, custom customization can be customized depending on the application.
（(For example, the software function is added to the optimum design of the optical system according to the object’s shape.)
Image of a cooperative company
It can be applicable to research and development applications and to use in production lines. For example, you can submit to the following companies:
1) Companies that want to measure spectral spectra of multiple wavelength bands.
2) We want to measure spectral spectra of multiple wavelength bands, but companies that do not need the number of bands (e.g., 141 bands) as many as hyperspectral cameras.
3) Though the spectral spectrum of a plurality of wavelength bands is measured, a company that has a choice of wavelength band cannot select any wavelength band in a conventional multispectral camera.
4) A company that uses an overseas hyperspectral camera and a multi-spectrum camera, but has problems in terms of price and performance.
(This product has an enhancement function of wavelength resolution, and it is recommended to customize the product according to the use of this product.)
Utilization of technologies and know-how (images)
By obtaining spectral spectra of multiple wavelength bands, various analyses can be performed.
As an example of using a multispectral camera, the following is a filter combination including wavelengths that can be applied to plant photosynthesis ability. We selected 5 types of filters: 532 nm (band 1), 570 nm (band 2), 660 nm (band 3), 750 nm (band 4), 760 nm (band 5). Optional (band 6) Plants differ in their wavelengths, and by combining band 4 and band 3, the photosynthetic activity of photosynthesis called normalized vegetation index (NDVI) can be quantified.
The following example shows what kind of analysis is possible by bulk measurement of multiple wavelength bands, and the case in which the hyperspectral camera (141 bands) is used.

Description of the terminology
[Reflection Spectrum]
The distribution of intensity per wavelength of electromagnetic waves obtained by passing electromagnetic waves through a spectrometer such as a prism or a grating is called spectral spectrum.
There are some spectral spectra, but the reflection spectrum that reflects the object is called reflection spectrum.
The multispectral camera measures the reflection spectrum of a material.
