An F/2 off-axis parabolic mirror assembly with protected gold mirror coating. This assembly is intended to attach to Sciencetech's LH-S lamp houses (also works with obsolete 201C-100 lamp houses). The assembly includes a kinematic three point adjuster to optimize optical alignment. A standard hole pattern on the input and output ends of the assembly can be used to mount this optical component to custom or third party systems with appropriate bracketing.
