The LTHP is used to shift a parallel beam laterally to any distance while maintaining the beam direction. In applications when the LTHP is vibrated, the exiting beam remains static and maintains perfect parallelism with the entrance beam. The beam deviation can be as accurate as one arc second. 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).
Patent No. 5301067
For applications where the major beam must be aligned with two or more other optical axes, see PLX Specification Sheet for "Rotary Movement Devices".
