WMB Water Cooling Mount (for 1.5″ lenses)

Introductionwater cooling laser mount

Model WMB mount is intended to provide cooling for mounted 1.5″ diameter ZnSe lenses. The
secondary purpose is to provide an interface between 1.5″ lenses (in M15 cells) and the appropriate
gas nozzle, which in most cases, will be the ‘MNA’ type described in data section 9.20.
The WMB mount does not accept any form of internal beamexpander.

Tolerances
All mechanical dimensions are toleranced to +/-0.1mm, except the mounting thread.
The mount thread is deliberately made to be a slightly loose fit into a female thread of (full) 44.0mm
dia x 1.0mm pitch.
(Users making a female thread to be a smooth or tight fit to an example WMB thread run the risk of
subsequent failure-to-fit with, eg: lens cells from other suppliers, or other ‘M15’ cells.
Associated products
The WMB mount fits directly to the following products:
FF38 fine focus mechanism (section 63.4)
CFF38 coarse/fine focus mechanism (section 63.3)
The WMB accepts:
All 15MZLF lenses (section 8.20)
All 15MHGP lenses (section 8.20)
All 14TF lenses (section 21.1)
See also section 21.3 for details of the use of WMB mount with 14TF series aberration-corrected
lenses.
Associated nozzles
The external (front) thread on the WMB mount is 58.0mm dia x 1.0mm pitch. This thread fits directly
to MNA nozzles.
The MNA nozzle type is intended for general-purpose use, with a wide range of adaptors to suit
various lens focal lengths. The MNA nozzles are suitable for use up to 25 Bar gas pressure.
