Patent number: 11175212Abstract: An apparatus and method for analyzing particulates in a sample is disclosed. The method includes placing the sample on a moveable stage in an apparatus having a tunable MIR light scanner and a visible imaging system, the stage moving between the MIR light scanner and the visible imaging system, providing a visible image of the sample, and receiving user input as to a region of the sample that is to be analyzed. The sample is then moved to the MIR light scanner, the MIR light scanner generating an MIR light beam that is focused to a point on the specimen and measuring light reflected from the specimen. The specimen is then scanned at a first MIR wavelength by moving the specimen relative to the MIR light beam, and particles are identified that meet a selection criterion. The MIR absorption spectrum of each of the identified particle is then automatically measured.Type: GrantFiled: January 30, 2020Date of Patent: November 16, 2021Assignee: Agilent Technologies, Inc.Inventors: Christopher Ryan Moon, Andrew Ghetler, Matthew Kole

Patent number: 10887532Abstract: An apparatus and method for generating images of specimens is disclosed. The apparatus includes an imaging system, controller, and user interface. The imaging system generates a plurality of component images of a specimen, each component image corresponding to a different viewing condition. Each image is represented by an intensity as a function of location on the specimen. The controller stores the component images and generates a compound image from a plurality of the component images. The compound image includes a weighted sum of first and second ones of the component images, the controller displaying the compound image on a display controlled by the controller. The user interface is adapted to control a weighting factor used in generating the weighted sum in response to user input. The controller redisplays the compound image after the weighting factor is changed in response to user input.Type: GrantFiled: April 3, 2019Date of Patent: January 5, 2021Assignee: Agilent Technologies, Inc.Inventor: Andrew Ghetler

Patent number: 10539504Abstract: An ATR scanning system and a method for positioning a specimen against the reflective surface of an ATR objective are disclosed. The scanning system includes an ATR objective, a controller, a stage, and a height profiler. The controller forms an image of the reflective surface. The stage moves a specimen in a direction toward the reflective surface at a speed determined by the controller. The height profiler measures a minimum distance between the specimen and the reflective surface as the z-axis stage moves the specimen at a first speed. When the specimen is a predetermined distance from the reflective surface of the ATR objective, the controller causes the z-axis stage to move toward the reflective surface at a second speed while forming approach images of the reflective surface to determine if the specimen is in contact with the reflective surface.Type: GrantFiled: September 30, 2018Date of Patent: January 21, 2020Assignee: Agilent Technologies, Inc.Inventors: Matthew Kole, Andrew Ghetler

Patent number: 10184835Abstract: An imaging scanner and a method for using the same are disclosed. The scanner includes a variable attenuator adapted to receive a light beam generated by a MIR laser and that generates an attenuated light beam therefrom characterized by an attenuation level. The scanner includes an optical assembly that focuses the attenuated light beam to a point on a specimen. A light detector measures an intensity of light leaving the point on the specimen, the light detector being characterized by a detector dynamic range. A controller forms a plurality of MIR images from the intensity as a function of position on the specimen, each of the plurality of MIR images being formed with a different level of attenuation of the light beam. The controller combines the plurality of MIR images to generate a combined MIR image having a dynamic range greater than the detector dynamic range.Type: GrantFiled: September 23, 2015Date of Patent: January 22, 2019Assignee: Agilent Technologies, Inc.Inventors: Charles Hoke, Christopher Ryan Moon, Andrew Ghetler, Yang Han

Patent number: 9863877Abstract: A scanner and an attenuated total reflection (ATR) objective for use in such scanners are disclosed. The ATR objective includes first and second optical elements and an input port. The input port receives an input collimated light beam that is focused to a point on a planar face of the first optical element by the second optical element such that substantially all of that portion is reflected by the planar face and no portion of the input beam strikes the planar face at an angle less than the critical angle. The second optical element also generates an output collimated light beam from light reflected from the planar thce that is characterized by a central ray that is coincident with the central ray of the input collimated light beam. A light beam converter receives the first collimated light beam and generates the input collimated light beam therefrom.Type: GrantFiled: September 23, 2015Date of Patent: January 9, 2018Assignee: Agilent Technologies, Inc.Inventors: Charles Hoke, Christopher Ryan Moon, Andrew Ghetler, Yuri Beregovski, Richard P.

Patent number: 9739661Abstract: A method and apparatus for obtaining reference samples during the generation of a mid-infrared (MW) image without requiring that the sample being imaged be removed is disclosed. A tunable MIR laser generates a light beam that is focused onto a specimen on a specimen stage that moves the specimen in a first direction. An optical assembly includes a scanning assembly having a focusing lens and a mirror that moves in a second direction, different from the first direction, relative to the stage such that the focusing lens maintains a fixed distance between the focusing lens and the specimen stage. A light detector measures an intensity of light leaving the point on the specimen. A controller forms an image from the measured intensity. A reference stage is positioned such that the mirror moves over the reference stage in response to a command so that the controller can also make a reference measurement.Type: GrantFiled: June 30, 2015Date of Patent: August 22, 2017Assignee: Agilent Technologies, Inc.Inventors: Andrew Ghetler, Adam Kleczewski, Richard P.
