Abstract

A microscope objective is disclosed comprising; a lens; a housing; a lens holder that is arranged to couple the lens to the housing; a first conductor and a second conductor, the first conductor and the second conductor extending along a sidewall of the housing, the first conductor and the second conductor being arranged to form at least one loop that is that is disposed about at least a portion of a perimeter of a field of view of the lens.

Claims (42)

1. A microscope objective comprising:

a lens;

a housing;

a lens holder coupled to one end of the housing and extending away from the housing, the lens holder being arranged to hold the lens and couple the lens to the housing;

a first conductor and a second conductor, the first conductor and the second conductor extending along a sidewall of the housing, the first conductor and the second conductor being arranged to form at least one loop that is disposed about at least a portion of a perimeter of a field of view of the lens,

wherein the lens holder includes one or more notches that are formed thereon.

2. The microscope objective of claim 1 , wherein the loop is formed on the lens holder, and the loop encloses the field of view of the lens.

3. The microscope objective of claim 1 , wherein the loop is formed over the lens.

4. The microscope objective of claim 1 , wherein the first conductor and the second conductor from a microstrip.

5. The microscope objective of claim 1 , further comprising a dielectric circuit board that is formed on the housing, wherein the first conductor and the second conductor are formed on the dieletric circuit board.

6. The microscope objective of claim 1 , wherein the loop is disposed around a perimeter of the lens.

7. The microscope objective of claim 1 , wherein at least a portion of the loop is disposed above or below a mid-portion of the lens.

8. A microscope objective comprising:

a lens;

a housing;

a removable clip that is coupled to the housing;

a lens holder that is arranged to couple the lens to the housing; and

a first conductor and a second conductor, the first conductor and the second conductor extending along a sidewall of the housing, the first conductor and the second conductor being arranged to form at least one loop that is disposed about at least a portion of a perimeter of a field of view of the lens,

wherein the loop is disposed on the removable clip.

9. A microscope objective comprising:

a lens;

a housing;

a lens holder that is arranged to couple the lens to the housing;

a first conductor and a second conductor, the first conductor and the second conductor extending along a sidewall of the housing, the first conductor and the second conductor being arranged to form at least one loop that is disposed about at least a portion of a perimeter of a field of view of the lens; and

a radio-frequency (RF) connector disposed on the housing, the RF connector being electrically coupled to the first conductor and the second conductor.

10. A microscope objective having an optical path, the microscope objective comprising:

a housing having a radio-frequency (RF) connector disposed thereon;

a lens holder that is coupled to the housing;

a first conductor and a second conductor that are electrically coupled to the RF connector, the first conductor and the second conductor extending along a sidewall of the housing and onto the lens holder, the first conductor and the second conductor being arranged to form at least one loop onto a surface of the lens holder, the at least one loop being disposed on the optical path of the housing.

11. The microscope objective of claim 10 , wherein the lens holder includes one or more notches that are formed in a surface of the lens holder.

12. The microscope objective of claim 10 , further comprising a dielectric circuit board that is disposed on a sidewall of the housing, wherein the first conductor and the second conductor are formed on the dielectric circuit board.

13. The microscope objective of claim 10 , wherein the loop is disposed around a perimeter of the lens.

14. The microscope objective of claim 10 , wherein at least a portion of the loop is disposed above or below a mid-portion of the lens.

15. A microscope objective having an optical path, the microscope objective comprising:

a housing;

a radio-frequency (RF) connector;

a lens holder that is coupled to the housing, the lens holder having a main surface extending across the optical path, the main surface having one or more notches formed thereon;

a first conductor and a second conductor that are coupled to a sidewall of the housing, the first conductor and the second conductor being arranged to form a loop,

wherein: (i) the first conductor and the second conductor are electrically coupled to the RF connector, and (ii) the first conductor and the second conductor extend along the sidewall of the housing and onto the lens holder.

16. The microscope objective of claim 15 , further composing a dielectric circuit board that is disposed on a sidewall of the housing, wherein the first conductor and the second conductor are formed on the dielectric circuit board.

17. The microscope objective of claim 15 , wherein the loop is disposed around a perimeter of the lens.

18. The microscope objective of claim 15 , wherein at least a portion of the loop is disposed above or below a mid-portion of the lens.
