I'd like to thank everyone for their input. I found out why the slit works. It turns out that its operation is based on fraunhofer diffraction.
As the pinhole approaches the beam spot size at the focal point, it experiences a broadening that makes the feild uniform while still letting...
I believe it is a gaussian beam, it's driving me nuts trying to figure out what they're trying to accomplish by having the slit there, one detail that I forgot to mention though, the slit is at the focal length of the lens.
I do not have a quantified parameter for the degree of uniformity, all...

I am an intern at a company looking to do schlieren photography and putting me in charge of developing a benchtop system. I've been at it for 4 weeks, and I think I've made some progress, but one problem I keep getting yelled at for is that the field isnt uniform.
The setup I...
