I did make an entire line of high temp devices that used a Pyrex lens.
They get placed in a cooled jacket, and get put right on a glass gob line

A single parabolic mirror yields the absolute best image on the sense

Usually, a thin film is over the tube as a dust shield.

The focus and field of view is determined by the tube length and
diameter, and the mirror focal length. The bolometer gets placed at the
focal point of the mirror. Exactly like a telescope.
Whoop-de-fucking-doo.
Are there any lenses on the Hubble Space Telescope's primary light
gathering system?
I rest my case.
What case, that you can't read?
