Abstract: A micro-optical bench device is fabricated by a process that provides control over one or more properties of the micro-optical bench device and/or one or more properties of optical surfaces in the micro-optical bench device. The process includes etching a substrate to form a permanent structure including optical elements and a temporary structure. The shape of the temporary structure and gaps between the temporary structure and permanent structure facilitate control of a property of the micro-optical bench and/or optical surfaces therein. The process further includes removing the temporary structure from an optical path of the micro-optical bench device.

Abstract: Aspects relate to mechanisms for enhancing the coupling of scattered light from a sample under test into a spectrometer. An optical device can include a reflective surface positioned apart from the sample and configured to receive a first portion of scattered light from the sample and to redirect the first portion of the scattered light back to one or more discrete spots on the sample in a non-random manner to produce redirected scattered light from the sample. The spectrometer may then be configured to receive coupled light from the sample including at least a portion of the redirected scattered light.

Abstract: Aspects relate to mechanisms for increasing the field of view of a spectrometer. An optical device may be configured to simultaneously couple light from different locations (spots) on a sample to the spectrometer to effectively increase the spectrometer field of view. The optical device can include a beam combiner and at least one reflector to reflect light beams from respective spots on the sample towards the beam combiner. The beam combiner can combine the received light beams from the different spots to produce a combined light beam that may be input to the spectrometer.

Abstract: A Micro-Electro-Mechanical System (MEMS) apparatus provides for self-calibration of mirror positioning of a moveable mirror of an interferometer. At least one mirror in the MEMS apparatus includes a non-planar surface. The moveable mirror is coupled to a MEMS actuator having a variable capacitance. The MEMS apparatus includes a capacitive sensing circuit for determining the capacitance of the MEMS actuator at multiple reference positions of the moveable mirror corresponding to a center burst and one or more secondary bursts of an interferogram produced by the interferometer based on the non-planar surface. A calibration module uses the actuator capacitances at the reference positions to compensate for any drift in the capacitive sensing circuit.

Abstract: A shadow mask having two or more levels of openings enables selective step coverage of micro-fabricated structures within a micro-optical bench device. The shadow mask includes a first opening within a top surface of the shadow mask and a second opening within the bottom surface of the shadow mask. The second opening is aligned with the first opening and has a second width less than a first width of the first opening. An overlap between the first opening and the second opening forms a hole within the shadow mask through which selective coating of micro-fabricated structures within the micro-optical bench device may occur.
