Not quite the right thread but the companies sticky isn’t a public post so I’ll share here.

I’ll have to order one for myself to see how the interaction goes but i’m hopeful, he seems quite nice and I like the hosts he uses. Here’s the site:
I’m learning about Scanning Fabry-Perot Interferometers, looks so interesting to me but not sure if I would have any practical use for them with what I do with lasers. My understanding is they can be used to measure the wavelength down to the nats back side in accuracy, but need a known reference to be used with them to do so.
