Hey everyone. So a few days ago I decided to take a risk and bid on a Bosch and Lomb monochromator. Anyway, long story short, I won it for about $230 and it arrived today!
Without further ado, here are the pictures that I know you guys have been waiting for!
Now, that's the device... what about some pictures of it doing what it's built to do... measure monochromatic light? (Or isolate light, really.) Well, first I should explain how I managed to get consistent results. I've found that if the laser enters the device off axis, it will not get a correct reading. So, I basically just stuck the laser right on the slit so that it got the maximum light through it while maintaining perpendicular entry. So, for example, I just stuck it right up against the argon laser and the greeNe! Heh.
Anyway, I bet you're wanting verification that it works, so here are some pictures of it taking measurements
In conclusion, it looks like it typically reads about 2-3nm high. I think I am seeing about 2nm resolution, too. I have the slits set pretty low. I'm trying to think of a way that I can maybe use specular reflections instead of direct incidence. Anyway, if anyone has any ideas, that'd be awesome
Alright, so that's everything. Hope you guys enjoyed!
