Abstract: A system for deposition of evaporated material on a substrate is provided. The substrate has a central axis. The system includes an evaporation vacuum chamber, at least one nozzle assembly, and a shadow mask. The nozzle assembly has a three-point plurality of point evaporation sources disposed adjacent to the central axis of the substrate and at a distance from the substrate whereby the nozzle assembly provides for molecules of evaporated material to arrive at the substrate at an incident angle of less than or equal to 5 degrees.

Abstract: A spectroscopic scanning device, a portable spectroscopic scanning system, and methods for using the spectroscopic scanning device are described that include at least one focusing element configured to collect light, a beam-steering element configured to direct a portion of the collected light from the at least one focusing element, and a detector configured to receive the directed light from the beam-steering element, wherein the beam-steering element is operable to successively select portions of light from a plurality of locations within its field of regard.

Abstract: Systems and techniques for optical spectrometer detection using, for example, IR spectroscopy components and Raman spectroscopy components are described. For instance, a system includes a first electromagnetic radiation source configured to illuminate a sample with a first portion of electromagnetic radiation in a first region of the electromagnetic spectrum (e.g., an IR source) and a second electromagnetic radiation source configured to illuminate a sample with a second portion of electromagnetic radiation in a second substantially monochromatic region of the electromagnetic spectrum (e.g., a laser source). The system also includes a detector module configured to detect a sample constituent of a sample by analyzing a characteristic of electromagnetic radiation reflected from the sample associated with the first electromagnetic radiation source and a characteristic of electromagnetic radiation reflected from the sample associated with the second electromagnetic radiation source.

Abstract: A system for identifying a gas sample includes a canister, a docking station, a thermal desorption device, and a spectrometer. The canister includes a sorbent and a valve. The docking station is configured to removably engage the canister. When the canister is engaged with the docking station, the canister is capable of fluid communication with a gas cell via the valve.
