An apparatus for processing substrates includes a continuum radiation source, a source manifold optically coupled to the continuum radiation source and comprising: a plurality of beam guides, each having a first end that optically couples the beam guide to the continuum radiation source; and a second end. The apparatus also includes a detector manifold to detect radiation originating from the source manifold and transmitted through a processing area, and one or more transmission pyrometers configured to analyze the source radiation and the transmitted radiation to determine an inferred temperature proximate the processing area.

A heating station for use with, for example, a high speed parallel manufacturing line for manufacturing insulated glass units, the heating station including at least two opposing infrared heaters that linearly heat spacer material that includes integrated temperature sensitive adhesive. Each of multiple linear infrared heaters includes a respective associated temperature sensor. The infrared heater and temperature sensor are coupled to a spacer heating controller that controls intensity and/or duration of heating of the spacer material and adhesive to provide optimal wetting and adhesive qualities. Individual control of the at least two opposing linear infrared heaters compensates for variable environmental conditions affecting spacer material at different locations around and insulated glass unit.

A method for enhancing vacuum tolerance of optical levitation particles includes steps of: (1) turning on a trapping laser to form an optical trap, loading the particles to an effective capture region of the optical trap, and collecting scattered light signals; (2) turning on the preheating laser, and directing a preheating laser beam to the captured particles; (3) adjusting a power of the preheating laser until a particle heating rate is larger than a heat dissipation rate; (4) turning on the vacuum pump, and stopping evacuating when a vacuum degree is greater than a vacuum inflection point of a first reduction of the effective capture region of the optical trap; and (5) turning off the preheating laser when the scattered light signals collected by the photodetector no longer changes. The present invention improves a stable capture probability of the particles in high vacuum environment.

An aerosol generating device including a housing of which is provided therein with a cavity for receiving a smokable material; a holding mechanism for holding the smokable material in the cavity along the radial direction and an infrared emitter located outside the cavity along the radial direction to radiate infrared rays to heat the smokable material. A distance between an inner surface of the infrared emitter and the central axis of the cavity is larger than the shortest distance between the holding mechanism and the central axis of the cavity, so that a certain space is maintained between the smokable material and the inner surface of the infrared emitter when the smokable material is received in the cavity, thereby preventing the infrared emitter from heating the smokable material by contact conduction.

An oven may facilitate heating, curing, and/or drying processes for manufactured items, such as shoe parts, using multiple groups of infrared sources. Efficiencies of the oven are achieved through a deliberate airflow characteristic, which is accomplished with a configuration of apertures extending through a circulation plate. A higher concentration of apertures is formed in the circulation plate near a center zone relative to zones near an entrance and exit to the oven. Further, the shape of the apertures in the circulation plate aid in improved airflow within the oven.
