| \\ The CHARA optics lab is a building within a building and is intended to provide thermal and vibrational stability. The main goal of the CHARA lab rules is to keep all optics and equipment safe from any hazards. The crucial issue being misalignment of anything. The amount of dust and dander must be kept to a minimum.\\ | \\ The CHARA optics lab is a building within a building and is intended to provide thermal and vibrational stability.

| Fill both chambers on the NIRO camera. Use the gloves and glasses provided on the shelf with the funnels and the thermos. It will normally take 1 liter of LN2 in the outer chamber and 1/2 liter in the inner chamber. Fill it until the LN2 bubbles out of the top. This camera is normally kept cool all the time, exceptions will be noted.\\ | Fill both chambers on the NIRO camera. Use the gloves and glasses provided on the shelf with the funnels and the thermos.
