On this page, you can find the legacy Breadboard Version of the spectrometer.
A breadboard means using off-the-shelve components like LEGO bricks to progress towards the technical requirements in terms of resolution and sensitivity.
The OpenRAMAN breadboard works with a 40 mW laser diode and a simple imaging assembly. Nonetheless, it provides a proven 12 cm-1 resolution and works extremely well on a lot of common solvents including alcohols, ketones, ester, nitroalkanes with SNR above 1:1000.
The bare breadboard version is the main platform for later development. Future upgrades will require you to build this one first.
Upgrade the breadboard to reach a 0.15…0.20 nm resolution with the spectrometer and save money at the same time!
Upgrade the cuvette holder to increase the signal-to-noise ratio of your spectrometer by allowing 4 times as much light!
Upgrade the laser of the spectrometer to increase resolution to 12 cm-1 or better! This upgrade also increases the SNR of your spectrometer.
