Abstract

A chromatic method and apparatus for conducting microscopic examinations at a plurality of magnifications provide for illuminating a microscopic object with a plurality of colors of light, conducting the light transmitted by the object along different paths for different colors, and producing different degrees of magnification along the different paths.

Claims (25)

WHAT WE CLAIM IS:
1. A chromatic method of conducting microscopic examinations at a plurality of magnifications which comprises the steps of: illuminating an object with a plurality of colors of light, conducting the light transmitted by said object along different paths for different colors, and producing different degrees of magnification along said different paths.
2. A method according to claim 1 wherein said step of illuminating said object is accomplished by employing selectively light of different colors, and including the step of conducting the light from said paths to a common terminal path.
3. A method according to claim 2 wherein said step of conducting includes the step of regulating the intensity of the light of said different colors to be substantially the same intensity when supplied to said common terminal path.
4. A method according to any one of claims 1, 2, or 3 including the step of generating said different paths by color differentiation.
5. Chromatic apparatus for conducting microscopic examinations of an illuminated object at a plurality of magnifications, in which neither the object nor any magnifying lenses are required to be moved, which v comprises: a color differentiating element disposed in the path of light transmitted from the illuminated object, said color differentiating element transmitting light of different colors in different directions therefrom and along first and second separate light paths, and a magnifying lens disposed in at least one of said separate light paths for producing different degrees of magnification along said different light paths from the illuminated object.
6. Apparatus according to claim 5 including a sensor disposed at the end of each of said separate light paths for receiving two different magnifications of the illuminated object.
7. Apparatus according to claim 5 or 6 which includes color selecting structure which causes said color differentiating element to receive simultaneously at least two different colors from the illuminated object.
8. Apparatus according to claim 5 further including structure for converging said first and second separate light paths into a common terminal path.
9. Apparatus according to claim 8 wherein said converging structure includes reflecting structure disposed in at least one of said separate light paths.
10. Apparatus according to claim 9 wherein said reflecting structure includes a color filter adapted to pass at least one color and reflect at least one different color.
11. Apparatus according to any one of. claims 8 to 10 including delivering structure for delivering to said common terminal path light of said colors having substantially the same order of intensity.
12. Apparatus according to claim 11 wherein said delivering structure includes a beam splitter.
13. Apparatus according to any one of claims 5 to 12 wherein said separate light paths are equal in length.
14. Apparatus according to any one of claims 5 to .13 which includes a second color differentiating element positioned in one of said separate light paths for directing at least one color along a third separate light path.
15. Apparatus according to claim 14 whic includes color selecting structure for selectively causing the light transmitted from the object to said color differentiating elements to b>e more than of two colors, each color being directed to a different one of said light paths.
16. Apparatus according to claim 14 or 15 including a sensor disposed at the end of each of said separate light paths for receiving different degrees of magnification of the illuminated object.
17. Apparatus according to claim 16 in which said color selecting structure causes at least one of said color differentiating elements to receive simultaneously at least two different colors from the illuminated object.
18. Apparatus according to any one of claims 5 to 17 further including an objective lens disposed in the path of light between the illuminated object and said differentiating element.
19. Apparatus according to any one of claims 5 to 18 including magnifying lenses having different magnifying powers disposed in different ones of said separate paths.
20. Apparatus according to any one of claims 5 to 19 wherein said differentiating element is a color filter adapted to pass on to said first light path at least one color and reflect on to said second light path at least one different color.
21. Apparatus according to claim 20 further including a second color filter disposed in said second light path to pass said reflected color while blocking passage of any reflected components of said passed color.
22. Apparatus according to any one of claims 5 to 21 further including means for illuminating said object selectively by light of different colors.
23. Apparatus according to any one of claims 5 to 22 in which said color differentiating element, said separate light paths, magnifying lens and the object are stationary at least during the production of the different degrees of magnification.
24. A chromatic method substantially as described with reference to the accompanying figure.
25. A chromatic apparatus substantially as described with reference to the accompanying figure. Tel-Aviv, October 13, 1974
