In applications when the LTHP is vibrated, the exiting beam remains static and maintains perfect parallelism with the entrance beam.
The LTHP is also useful where one of the mirrors is a 50-50 beamsplitter. This configuration produces two output beams, precisely parallel to each other, traveling in the same direction. In addition, the LTHP is extremely temperature stable because all component parts have the same coefficient of thermal expansion (CTE).
For applications where the major beam must be aligned with two or more other optical axis, see PLX Specification Sheet for "Rotary Movement Devices".
