90851/61 Inline Folded Tunable telescope configuration \ Beam expander- 1''/25mm-1''/25mm Parabolic mirrors based with/without pinhole

90851A-M


General

Optical telescope configurations provide the ability to change the apparent angular size of objects. The 90851/61 telescope is based on off-axis parabolic mirrors (1’’/25mm or 2’’/50mm) with various magnifications. This design is tunable and allows the use of large focal-length curved mirrors with small telescope footprint. The 90861 module is targeting broadband beam Filtering. It has an additional mount (20551 or 20680) for a pinhole. The beam is focused onto a pinhole that is positioned along the optical grid and filters the higher order spatial modes of the beam.
