Alignment And Enclosure
=======================

UUID: ``C84AA8D3-91D6-42CF-A6E7-28E7EDCF87AE``

Initial optical work uses a standard optical breadboard and post-mounted
hardware so the slit, mirrors, grating, and detector can be adjusted before the
final enclosure is fixed.

Alignment priorities are:

* Place the first-order spectrum across the useful CCD width.
* Minimize defocus and tilt that broaden narrow spectral lines.
* Preserve the selected slit-width tradeoff between throughput and resolution.
* Record grating, mirror, and CCD positions once a repeatable setup is found.

The final enclosure must block ambient light and protect internal optics from
physical disturbance. Enclosure constraints should be introduced after the
breadboard alignment can meet wavelength coverage and FWHM targets.
