In some applications a high pressure window is needed to seal the process. These windows can
be purchased as spare parts and they exist in 3 versions namely, DN65/PN6, ANSI 4"/150lb and
a special version that will adapt the DN65/PN6 flange on the optics housing to a DN80/PN16
flange on the process - see the figure below.
