Abstract: Provided are systems and methods related to hybrid reflective microscope objectives and lens systems used in a spectroscopy system. The objective lens system includes a primary aspheric mirror having a first R-value; and a secondary aspheric mirror having a second R-value smaller than the first R-value, where in the objective lens system has a working distance of at least 20 mm and a numerical aperture of 0.29-0.65, and wherein surfaces of the primary and secondary aspheric mirrors have a non-zero sixth order aspheric parameter.

Abstract: A microscope for examining a specimen configured to receive a first light source or a second light source. The first light source being configured to emit a first output light through a first pupil, and the second light source being configured to emit a second output light through a second pupil that is different than the first pupil. The microscope comprises a frame, a source objective, and first and second optical assemblies. The first and second optical assemblies are removably connectable to the frame. The first optical assembly comprises a first set of optical elements that are configured to pass the first output light to an imaging pupil of the source objective, and the second optical assembly comprises a second set of optical elements configured to pass the second output light to the imaging pupil.
