Appl. No.:

08/202300

Inventors:

Robert M. Carangelo - Glastonbury CT, US
Paul C. Jette - Bethel CT, US
Jack Kisslinger - Verona WI, US

Assignee:

MKS Instruments, Inc. - Andover MA

International Classification:

H03K 12/00

US Classification:

327184, 327233, 327258, 356345

Abstract:

Eight or more transition points are generated during a given period, and are used in tracking movement of an interferometer reflector. Duty cycles of generated square waves are used to establish precise intervals between the transition points, and precise wave-phase relationships.

Appl. No.:

11/115039

Inventors:

Stuart Brorson - Brighton MA, US
Carl Brouillette - West Hartford CT, US
Robert Carangelo - Glastonbury CT, US
David Marran - Durham CT, US

Assignee:

MKS Instruments, Inc. - Wilmington MA

International Classification:

G01B 9/02
G01J 3/45

US Classification:

356451000

Abstract:

A method and apparatus for measuring radiometric signals. An infrared energy signal is directed through a sample and combined with a selected signal to reduce the effect of analog-to-digital converter nonlinearity. The combined signal is processed to, for example, accurately and repeatably identify the types of and concentration of molecules within the sample.

Filed:

Feb 25, 1994

Appl. No.:

8/201814

Inventors:

Robert M. Carangelo - Glastonbury CT
David D. Wright - Vershire VT

Assignee:

On-Line Technologies, Inc. - East Hartford CT

International Classification:

G01N 1506

US Classification:

250573

Abstract:

A folded-path gas cell employs an elliptical concave mirror in confronting relationship to two substantially spherical concave mirrors. At least one of the spherical mirrors, and usually both, are formed with an added cylindrical component to increase orthogonal focii coincidence and thereby to increase the radiation energy throughput characteristic of the cell.

International Classification:

G01B 902

US Classification:

356346

Abstract:

A multiplicity of one-piece flexure plates are assembled in pairs to provide a support system on which a retroreflector may be mounted for reciprocal motion. Combined with balance bodies, the flexure plates provide a support system having portions that are dynamically and statically balanced with one another, irrespective of orientation, so as to thereby immunize the unit against extraneous forces. The motion transfer assembly is especially adapted for use to support a moving retroreflector in a two-arm interferometer that may further include a beamsplitter assembly constructed from a one-piece, integrally formed body, the body having convergent, optically flat planar surfaces of specular reflectance, and means for adjustably mounting a beamsplitter therein. The spectrometer is of modular construction, and employs an integrated clocking sub-assembly as well as a light-weight voice-coil motor.

International Classification:

G01N 2135
G01N 2155

US Classification:

356445

Abstract:

A non-contact spectroscopy system includes scanning head structure with transmitting optics for focusing radiation onto the surface of material to be analyzed, and receiving optics for collecting radiation reflected from the surface of the material and directing the reflected radiation onto optic fiber structure for transmission to spectroscopic analyzer structure.

Filed:

Dec 28, 1992

Appl. No.:

7/997457

Inventors:

David B. Fenner - Simsbury CT
Robert M. Carangelo - Glastonbury CT

Assignee:

Advanced Fuel Research Inc. - East Hartford CT

International Classification:

G01J 351
H01L 27146
H01L 3900

US Classification:

2503362

Abstract:

An array of superconducting bolometers, assembled with a superposed interference layer of graduated thickness, provides a microelectronic detector assembly that discriminates radiation impinging thereon, as a function of wavelength, and that can be used for transform spectroscopy, color-imaging, and the like. The interference coating will preferably be of step-like form, with each plateau of the structure being of the same spatial extent as the bolometer with which it is associated.
