US Patent:
D2581442, Feb 3, 1981
Filed:
Nov 11, 1977
Appl. No.:
5/850568
Inventors:
Eli A. Kallet - New York NY
Samuel Cravitt - Hartsdale NY
Leonard R. Caputo - Yonkers NY
Assignee:

International Classification:
D2402
US Classification:
D24 17

Enhanced Fluorescent Emission

View page
US Patent:
43458378, Aug 24, 1982
Filed:
Jun 27, 1980
Appl. No.:
6/163846
Inventors:
Eli A. Kallet - New York NY
Assignee:
Farrand Optical Co., Inc. - Valhalla NY
International Classification:
G01N 2164
US Classification:
356317
Abstract:
Monochromatic exciting light is transmitted in a forward direction from a source through a sample to a spherical mirror. The spherical mirror reflects the light in a backward direction through the sample and images the light upon a flat mirror. The flat mirror reflects the light in the forward direction, through the sample, to the spherical mirror, thereby causing the light to be reflected in the backward direction, through the sample, to the source. The reflections increase the optical path length of the light through the sample, thereby enhancing a fluorescent emission therefrom.

Convertible Dual Beam Differential Spectrofluorometer And Absorption Meter

View page
US Patent:
41533690, May 8, 1979
Filed:
Nov 11, 1977
Appl. No.:
5/850569
Inventors:
Eli A. Kallet - New York NY
Samuel Cravitt - Hartsdale NY
Assignee:
Farrand Optical Co., Inc. - Valhalla NY
International Classification:
G01J 330
G01J 110
US Classification:
356318
Abstract:
A dual beam differential spectrophotometer using a rotating chopper wheel having reflective transparent, and opaque sectors transmits light alternately through standard and sample material cells for comparison. Diffuse reflectors insertable in the material cells permit the apparatus to be used either as a differential spectrofluorometer or as a differential absorption meter.

Recording Transmission And Emission Spectra

View page
US Patent:
43056601, Dec 15, 1981
Filed:
Jun 27, 1980
Appl. No.:
6/163847
Inventors:
Eli A. Kallet - New York NY
Assignee:
Farrand Optical Co., Inc. - Valhalla NY
International Classification:
G01N 2159
G01N 2164
US Classification:
356 73
Abstract:
A first monochromator includes a diffraction grating that is adapted for occlusion by a mirror. When the mirror occludes the grating, a white light input is transmitted through the first monochromator and through a sample under test, thereby causing a transmission of non-absorbed light from the sample. When the grating is unoccluded, monochromatic light is transmitted from the first monochromator so that a selected bandwidth of fluorescence excitation energy is incident on the sample. Fluorescence emission from the sample is diffracted by a second monochromator which provides diffracted light which is recorded by a vidicon.
