Product Details

Hamamatsu C12666MA MEMS u-Spectrometer
Mfr. Part #
Product Description

This group buy is for a Hamamatsu C12666MA Micro-spectrometer. Its spectral response lies mostly in the visible range, 340 to 780 nm, with 15 nm of resolution. Its fingertip size of 20.1 × 12.5 × 10.1 mm and light weight of 5g make it very interesting to integrate into small embedded systems with a need to detect color.

Stay up to date on the progress of the breakout board for this product here, we will be carrying that product as soon as it is complete.


And whether you are fan of this part or not, you must check it out in action in Peter Jansen's "Open Source Science Tricorder" project here

Why GroupGet?

If you are looking to add electronic color detection in a small footprint to your projects, this component is definitely worth a prototype. It's also over $50 cheaper than buying in single quantities. Due to long factory lead times for the part, we are doing batches of 10 with limited timeframes. As soon as we get 10 orders they will go directly to Hamamatsu and a new batch will open.

How it works

This is a group buy campaign that needs to acquire at least the stated minimum amount of pledges from backers like you before the Unit Deliverable and any Add-Ons ship. We do not charge anyone until the Progress above hits 100% or greater, otherwise there is no charge. All campaign products are vetted as existing and functional so your order will be fulfilled within the Factory Lead Time if the campaign succeeds. Please see our FAQ page for more details on our billing process.

    Where can I find the calibration data provided by Hammamatsu? This data is specific to each sensor, and measured at time of manufacture.
