A lens assembly adapted to be connected to a CRT and affixed to mounting structure
in a projection television cabinet. The lens assembly includes a tubular lens mount
having a longitudinal axis and at least a first optical lens element mounted along
the longitudinal axis. A tubular focus mount extends along the longitudinal axis
and fastening and locking structure connects the lens mount to the focus mount
after a focus mount position is obtained. A CRT coupler is formed integrally with
the focus mount and includes structure for securing a CRT and for securing the
coupler to the mounting structure within the television cabinet. A second optical
lens element is mounted to the CRT coupler. A flexible bladder may be used to contain
coolant fluid between the CRT and the coupler.
