MOEMS technology that underlies mini-spectrometers

The mini-spectrometer is a product that integrates Hamamatsu’s MOEMS (micro-opto-electro-mechanical-systems) technology, which combines optical technology including opto-semiconductor devices and optical systems and MEMS technology, with circuit and software.

The detector serving as the core of the mini-spectrometer is a proven Hamamatsu image sensor in analysis and measurement fields. Since Hamamatsu develops its own grating, which performs spectroscopy, grating with various specifications (high resolution, wide spectral range, high diffraction in the ultraviolet region, etc.) can be mounted on its mini-spectrometers.

Applications

Color measurement (e.g., LED light source)

A mini-spectrometer is used to perform spectral measurement and inspect LEDs or the like.

Sugar content measurement

Absorbance is used in applications such as handy brix meters, which measure sugar content.

Display color measurement

The emission spectrum of LCDs is monitored with a micro-spectrometer.

Film thickness measurement

White light interferometry is used to measure the spectrum peak count, film refractive index, and fi lm thickness from the light incident angle.

Plastic screening

Plastic screening is performed by using the fact that when near infrared light is directed at plastic, the wavelengths that are absorbed varies depending on the material.

Fluorescence measurement

Emission spectrum of fluorescent materials, such as fluorescent lamp and organic EL devices, is measured.

Environmental analysis

Mini-spectrometers are used in environmental analysis of water, soil, and the like.

Color adjustment

Integrated into color printers and other printing equipment, microspectrometers monitor the color of printed materials.
