- Weight: 5 g
- Spectral response range: 340 to 850 nm
- High sensitivity
- Spectral resolution: 15 nm max.
- Trigger-compatible
- Hermetic package: High reliability against humidity
- For integration into mobile measurement equipment
- Wavelength conversion factor is listed on test result sheet.

Measurement example

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.

Application examples


Besides a CMOS image sensor chip integrated with an optical slit by etching technology, this product employs a reflective concave blazed grating formed by nanoimprint. In addition, the glass used in the light path of the previous product is not used in this product, making it extremely compact.
