Water Cooling Mounts for 14TF/15TF Lenses
Lenses used to focus high power CO2 laser beams may need some indirect cooling. Model WMB
water cooling mount is designed to accept the 14TF series of lenses, or any 1.5″ (38mm) diameter
ZnSe lens mounted in a type M15 cell. The WMB unit interfaces with other equipment, such as
focusing heads, via a 44mm x 1.0 pitch thread. Model WMC mount is identical to model WMB,
except in that it is designed to accept 15TF series lenses.
