Hi

Where can I buy chip gratings 50mm burst and line?

Thanks, Maciej

Any idea where I can get a simple linear array of lines, a grating with 1000 lines per mm for making a simple way to gauge a beam's wavelength? Or should I be looking at better ways to do this? I need to see how a red diode beam changes with temperature, and it has to be cheap.

I would think that you could use a prism. Shine the laser through the prism let it shine on a wall 10 feet away mark the starting point, let it heat up and see if it moves..

Haven't tried it just an idea.. I don't know how the hell you would calibrate it though...

HeNe and 532 nm DPSS. Hopefully enough to do calibration, they're both steady. Can use leaky 1064 from the DPSS for the low end as well, if it has any.

I thought of a prism, and might do that, but I think the grating will make more deflection from a smaller object, (is the impression I got when reading stuff in times past), and also it might be less prone to heat problems. Good call though, I didn't think about heat before. I guess you meant the laser, but I think a prism itself might have a small thermal drift that could be smaller or absent with a grating.
