We are building a light detection system which works like a clock’s hand: an aluminum profile (the “hand”,shown in schematics) carrying detector assemply on its one end rotates around the other end; as the aluminum profile is quite long (2200L*40W*40H mm) and heavy (~10kg)，we will add a...
Mech_Engineer,
Thank for your reply. I do have experience with similar systems and detailed specs for accuracy, torque, moment of inertia and deg of freedom etc., just wanted to give a very brief description without flooding lots specs.
What I am trying to do is a much more simplified version...
Hi Folks,
I'm building an ellipsometer-like system similar to the one shown in attached picture, but with much longer and thinner rotation bars carrying viewing optics assembly (VOA) and incident optics assembly (IOA), respectively; the system would require that the sample holder plane can...

I'm trying to reproduce a plot of Sun's black-body behavior like this one:

Problem is, after I convert the black-body radiance to irradiance, its curve is way too high as compared with...

Problem is, after I convert the black-body radiance to irradiance, its curve is way too high as compared with measurement. The measurement data is taken from...
