Mini-spectrometer SMD series

Absorption spectrum measurement of bacon

A demonstration module with a built-in the mini-spectrometer SMD series was used to measure the absorption spectrum of bacon. Since fat absorbs light near 930 nm, its response intensity can be used to measure fat mass.

Absorption spectrum measurement of apple

A demonstration module with a built-in the mini-spectrometer SMD series was used to measure the spectrum of apples before and after they were damaged. Chlorophyll (around 670 nm) and sugar (around 980 nm) are typical indicators of the nutrition and taste of vegetables and fruits. Spectral analysis is used for these tests.

Mini-spectrometer Micro series

Color measurement

A demonstration module with a built-in the mini-spectrometer Micro series was used to measure the spectrum of color sample. Because the Micro series is small, it can be mounted on various color measuring devices such as color adjustment of color printers and dimming of LED lighting.

Mini-spectrometer TF series

The unseen side of pharmaceutics: NIR spectrometers

Spectrometers for near-infrared measurement uncover a world unseen to the human eye. In this video, we’ll go over why the information revealed in this spectral range is important to the pharmaceutical industry, how these measurements are made possible through different spectrometer designs, and where else NIR spectrometers can make vital contributions.

Fluorescence measurement

This is an example of measuring fluorescence from a 1000 ppm quinine solution (buffer solution: dilute sulfuric acid).

White LED and 3-color LED

This is an example of measuring emissions from a white LED and 3-color LED.

White LED light contains wavelength components of various colors as well as blue, and appears white because those colors are mixed together.

Film thickness measurement

Here we show an example that measures the film thickness of 10 μm thick food wrap (polyvinylidene chloride). In film thickness measurement utilizing white light interferometry, a rippling interference spectrum is obtained due to reflections between the front and back surfaces of the film. The film thickness can then be determined by calculation from the spectral peak count, wavelength range, refractive index of film, and the angle of incident light.
