Intrigued to see what we'll come up with. I'm all about compactness in the form of lab mobility and deployment.

I am struck by the possibility of making a 3Dprinted or lasercut LED/Cuvette/CD holding case with a manual slider to move one part to select which band of light passes through the cuvette. With a photoresistor along the lightpath and at right angles to the cuvette, that'd give you a fair bit of spectro function, right?

The most expensive part, as always it seems, is the light source..
