PST etalon spacer

Post by swisswalter »

I read some where about the need of having to know the thickness of the spacers used on an etalon. As I have only one broken etalon of a Ha PST I measured the two spacers left on it.

using the mikroscope I find ~200 µm, using a JKA-feintaster I get an average of 204 µm

hope that helps a little
