who is the Littrow prism named for?[edit]

Trying to make one more link. --AJim (talk) 19:52, 11 March 2015 (UTC)

Life[edit]

The Article Heinrich von Littrow claims that J.J. was married to one "Karoline von Ulrichsthal" and had at least 13 sons with her. If there's a decent source for that info it should be added to the article. --BjKa (talk) 09:40, 4 September 2015 (UTC)

Moon Crater[edit]

I don't dispute the naming of the moon crater after him, but the claim needs a citation. Maybe some NASA website has some info on the naming of moon features? --BjKa (talk) 09:40, 4 September 2015 (UTC)

Diffraction gratings[edit]

Diffraction gratings can be set up in the Littrow configuration, as described in the article on blazed gratings and in the Diffraction Grating Handbook by Christopher Palmer published by Newport Corporation. Is the Littrow configuration named after Joseph Johann von Littrow?

Apparently, yes—according to pg 298 of Hans Zappe's text on The Fundamentals of Micro-Optics. (Unfortunately, the particular page does not appear to be available in Google Books' on-line preview.) I've updated the article with this statement, and reference, and put a link to this article into the page on blazed gratings. Supasheep (talk) 22:21, 13 February 2018 (UTC)

Pronunciation[edit]

How is Littrow pronounced?

At least among English speakers here in Canada: 'Li', as in Lithium, and 'trow', as in retro. I don't have any real 'source' for this, unfortunately. Supasheep (talk) 22:23, 13 February 2018 (UTC)
