 +\\===== Lenses =====
 +The two focusing lenses (one for each chamber) used are of the plano-convex type, and are made of UV grade fused silica.  The lenses used have no coatings, and have different focal lengths.  The lens used with the Thermionics chamber is OptoSigma part no. 014-1315.

 +===== Windows =====
 +There are many windows on the thermionics chamber.  However, there are two UV grade laser windows.  Each of these is mounted in a ConFlat flange.  Each of the laser windows are made of fused silica, and measuring with the Coherent power meter, have a loss of approximately 10%.
