I want to measure the absorbance spectrum of some solutions, in the 400-700 nm range. I've always used regular "optical glass" cuvettes for this. But I've been wondering, is this really necessary?
If the glass looks transparent to the eye, then its absorbance in the 400-700 nm range is negligible. And if the surface looks smooth and clear, then it shouldn't disperse the incident light. So any thin sheet of smooth transparent glass should work, right?
For example, I could try to build my own cuvette simply by getting a few microscope slides and tops, (which are thin, flat and smooth panels of glass) and gluing them together with a suitable adhesive.ç
Edit: What I mean is, creating a hollow 3D shape with 4 rectangular panels and a smaller square bottom panel, by gluing thin pieces of flat smooth glass (microscope slides for example). This would be a "home-made" cuvette. (I'm not proposing to simply sandwich a droplet between to slides!)
Has anyone tried this? Is there a reason why it wouldn't work?
