High sensitivity in the near infrared region (to 1050 nm), ultra-compact grating type spectrometer


The C14384MA-01 is an ultra-compact grating type spectrometer that provides high sensitivity in the near infrared region. As such, it is capable of acquiring continuous spectrum. The product has been downsized through Hamamatsu unique optical design, which helps to further reduce the size of mobile devices.

-Ultra-compact: 11.5 × 4.0 × 3.1 mm (Flexible cable not included)
-Ultra-lightweight: 0.3 g
-Spectral response range: 640 to 1050 nm
-High sensitivity: 50 times (λ=1000 nm) the previous product (C11708MA)
-Flexible cable included

Measurement example

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.
