Abstract
The specification discloses a window assembly for an analytical furnace enabling the window to be readily and easily removed and reinstalled to facilitate servicing of the window. The assembly includes a one-piece fused silica housing having concentric inner and outer tube portions. The outer tube portion defines a transverse slot through which a window is inserted to overlie an end of the inner tube. A spring is included to bias the window into engagement with the inner tube to reduce airflow and heat loss therebetween.
