Abstract: An optical component includes a substrate having a first optical surface located opposite a second optical surface with at least one of the first optical surface or the second optical surface including a lenslet array formed therein. The optical component also includes an anti-reflective coating located on the first optical surface, a bandpass filter coating located on the second optical surface, and at least one obscuration located on the substrate. The obscuration is configured to block a transmission of light between the first optical surface and the second optical surface.

Abstract: Systems and methods are disclosed for generating an elastic stiffness map for a volume of an ophthalmic tissue of an eye of a patient. Exemplary systems and methods involve a laser assembly, an optical scanning assembly, an objective lens assembly, a beam control assembly, an eye camera assembly, and a Brillouin spectrometer assembly. Systems and methods can operate to transmit x,y coordinate scan control signals to the optical scanning assembly, transmit z coordinate scan control signals to the objective lens assembly, and generate the elastic stiffness map for the volume of the ophthalmic tissue of the eye based on Brillouin signals generated by a Brillouin spectrometer of the Brillouin spectrometer assembly.

Abstract: A spectrometer design offering good balance between resolution and throughput using just two aspheric toric mirrors and no detector lens and having improved stray light interference reduction through use of light traps and light absorbing coatings is disclosed.

Abstract: An in-line filter holder that easily attaches between a light source and spectrometer in order to pre-filter and/or attenuate the spectrum that enables the easy insertion of one or more off the shelf filters is disclosed.

Abstract: A modular linear solar energy collection system comprises one or more reflector units each having a light-weight generally planar aluminum frame that mounts a number of solar panels in a fixed position at angles which progressively increase from the frame centerline outwardly to its perimeter so as to collectively form a surface having a shape approximating that of a parabola. Sunlight incident on the solar panels is reflected by a combination of secondary and tertiary reflectors onto a receiver tube mounted in a fixed position concentric to the centerline of the frame. The frame is connected to a drive mechanism operative to pivot the frame and solar panels in order to track the position of the sun during the course of a day.
