Abstract

This disclosure is directed to a system and method for changing an angle of incidence of a filter or filter wheel.

Claims (20)

1. A system, comprising:

a first filter assembly comprising

a first filter, a base, a retainer, and two or more bearings,

wherein the first filter is retained between the base and the retainer, wherein a first side of the base comprises one or more bearings, and wherein an opposing second side of the base comprises one or more bearings; and

a cam,

wherein the cam is configured to contact at least one bearing of the first filter assembly and to rotate the first filter assembly from a first position to a second position.

2. The system of claim 1 , wherein the first position of the first filter assembly provides a first angle of incidence of a light on the first filter, and wherein the second position of the first filter assembly provides a second angle of incidence of the light on the first filter.

3. The system of claim 2 , wherein the first angle of incidence of the light on the first filter ranges from 0° to 89.9°, and the second angle of incidence of the light on the first filter ranges from 0° to 89.9°.

4. The system of claim 2 , wherein the first and second angles of incidence of the light on the first filter are selected from any angle of incidence ranging from approximately 5° to 60°, and wherein the first and second angles of incidence of the light on the first filter are not equal.

5. The system of claim 1 , further comprising a motor adjoined to the cam.

6. The system of claim 1 , wherein the base and the retainer each comprise a main body and one or more protuberances extending from the main body towards the first filter.

7. The system of claim 5 , further comprising an adapter comprising a motor segment and a filter segment, wherein the adapter is adjoined to the motor.

8. The system of claim 7 , wherein the motor segment comprises a main body comprising a spindle bore through which a spindle of the motor can be inserted.

9. The system of claim 8 , wherein the motor segment further comprises a stop projecting in direction away from the motor to inhibit rotation or movement of the cam beyond a certain point.

10. The system of claim 7 , wherein the filter segment comprises a stanchion adjoined to a first arm and a second arm, and wherein the first and second arms each include at least one cut-out being sized and shaped to receive at least one bearing of the filter assembly.

11. The system of claim 10 , wherein the stanchion comprises a stopper to set a travel limit on the filter assembly.

12. The system of claim 11 , wherein the stopper is a screw, rod, dowel, post, spring, overhang, or combinations thereof.

13. The system of claim 1 , further comprising one or more additional filter assemblies, wherein each additional filter assembly comprises a filter.

14. The system of claim 13 , wherein no two filters have the same bandpass profiles.

15. The system of claim 13 , wherein at least two filters have the same bandpass profiles.
