US Patent:

48757730, Oct 24, 1989

Filed:

May 6, 1988

Appl. No.:

7/191262

Inventors:

Richard Burns - Webster NY
James Defendorf - Rochester NY
Edward King - Fairport NY
Cornelius McCarthy - Pittsford NY

Assignee:

Milton Roy Company - St. Petersburg FL

International Classification:

G01J 318

US Classification:

356328

Abstract:

An optical system for a multidetector array spectrophotometer which includes multiple light sources for emitting light of selected wavelength ranges and means for selectively transmitting the selected wavelength ranges of light to respective slits of a multi-slit spectrograph for multiple wavelength range detection. The spectrograph has two or more slits which direct the selected wavelength ranges of the light spectra to fall upon a dispersive and focusing system which collects light from each slit, disperses the light by wavelength and refocuses the light at the positions of a single set of detectors.

Filed:

Aug 15, 1996

Appl. No.:

8/698419

Inventors:

Cornelius J. McCarthy - Pittsford NY

Assignee:

Accuracy Microsensors, Inc. - Pittsford NY

International Classification:

G01N 2125

US Classification:

356406

Abstract:

Improved apparatus for low cost measurement of spectral intensity distribution of light energy reflected from surfaces of or transmitted through objects or materials, using solid state emitters and detectors. The measurement results remain consistent in spite of variations in component characteristics or temperature.
