| jenjimah | " I just looked up the transmission spectrum of borosilicate glass and you're right I think it's fine. I might just try the microscope slide idea. I..." | Read more » | almost 4 years ago | |||
| jenjimah | " ^^^ I just realized you were referring to line spacing in microns, not lines/cm! Now it makes sense. " | Read more » | almost 4 years ago | |||
| jenjimah | "Also - I like the idea of microscope slides, except that glass strongly absorbs UV <400nm. I'm not sure of how well the pi NoIR is on that range..." | Read more » | almost 4 years ago | |||
| jenjimah | "Yes, so far I'm trying to accomplish all those 3 points. As for the slit, I made it from a razor blade so it should fulfill the criteria. I compare..." | Read more » | almost 4 years ago | |||

| jenjimah | "Sure I'll post a question about it! After stewing on it a while, I don't think it should be a huge issue in most relevant contexts, (esp. for other..." | Read more » | almost 4 years ago | |||
| jenjimah | "Thanks! It looks like khufkens predicted the response from >700 as the data was not yet available. If you look at the spectrum published by Sony..." | Read more » | almost 4 years ago | |||
| jenjimah | " Great fodder for thinking about. 1) Agreed, having an individual light measurement per plant has advantages in certain scenarios. I guess it comes..." | Read more » | almost 4 years ago | |||

| jenjimah | "So I was reading about minimum exposure time of the Pi cameras and learned that it uses something called a "rolling shutter", which means it reads ..." | Read more » | almost 4 years ago | |||
| jenjimah | " Yes that's exactly what I intend to do with the sun. Given sensor stability, and no shifts or changes in the spectrometer's build, calibration wou..." | Read more » | almost 4 years ago | |||
