Name for one kind of Czerny-Turner monochromator configuration?

Click For Summary

Discussion Overview

The discussion centers around the identification of a specific name for a Czerny-Turner monochromator configuration, particularly one where the two mirrors combine to form a single monolithic mirror with a single radius of curvature. Participants explore existing terminology and configurations related to this design.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about a specific name for a Czerny-Turner monochromator configuration where mirrors M1 and M2 merge into a single mirror M12.
  • Another participant suggests that the name they were looking for is the Fastie–Ebert monochromator.
  • A different participant mentions familiarity with the configuration being referred to as Ebert-Fastie or simply Ebert.
  • One participant expresses a desire for clarity in questions to facilitate self-answering and encourages further inquiries into related devices.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the naming of the configuration, with multiple terms being proposed and some uncertainty about the correct terminology.

Contextual Notes

There is a lack of clarity regarding the specific characteristics that differentiate the configurations mentioned, and the discussion does not resolve the naming conventions for the monochromator design.

TL;DR
searching for name of single-mirror C-T monochromator configuration
Can anyone say if there is a specific name for the Czerny-Turner monochromator configuration shown below, but specifically when the two mirrors M1 and M2 extend into each other and combine forming one monolithic mirror M12 with one single radius of curvature? I thought I saw such a design years ago, and I'm revisiting an old project in which I'm actually trying to build it, but it would help to reference any existing work.

Nevermind: apparently, the name I was looking for was Fastie–Ebert monochromator.
 
Welcome to PF.
Where if you can express yourself clearly, and ask the right question, you can answer it yourself.
We look forward to your next good question, and an introduction to another interesting esoteric device.

I'm more familiar with it being called Ebert-Fastie, or simply Ebert.

Below are three configurations I am most familiar with.
