C12666MA Micro-Spectrometer by Hamamatsu Photonics

Description

The Hamamatsu C12666MA MEMS Micro-spectrometer is a unique and high quality electronic color sensor in the size of a fingertip. It is less than half of the volume of the previous generation of miniature spectrometers and because of that it landed on our radar as an interesting new capability for portable embedded systems.

Its spectral response lies mostly in the visible range with 15 nm of resolution. With its small size and light weight, it can be integrated into compact portable embedded systems to detect color in applications such as organic compound analysis (food products, biological and environmental analysis, crime scenes) and color matching or detection of LED's, paints, and materials. It can also be integrated into industrial control systems that rely on exact colors for a given process.

We now ONLY carry a higher resolution version of this part - the C12880MA.

To enable rapid prototyping with this device, GetLab has created a simple Arduino-compatible breakout board with an integrated SONY SLD3134VL (405nm violet/blue 20mW) laser diode to use as an illumination source. A picture of the full kit is shown below but note that the board and sensor are currently sold separately. We have also created reference firmware for the breakout board.

This product is only sold with minimum order quantities from the manufacturer and has long lead times. Get a head start on your experimentation by joining our current GroupGet round to get it faster and only in the quantity that you need. Get it Now.
