Experiences with new webcam and thick-film gratings

we ordered the widely available webcam from aliexpress HM1355, approx 3USD. The gratings are more difficult to find, and we are testing 300 & 600 lines/mm from ali.

First experiments showed we might wanna use higher line densities. also the angle / position for the cam and gratings needs to be adjusted. no cheap distributor found yet.

images are a bit too noise. maybe try wider slit...

Measurements below where taken against "sun-light" on a cloudy day... veeery cloudy :-(
