Abstract

A device comprising: a printed circuit board (PCB); a sensor package mounted on a first side of the PCB; electronics mounted on a second side of the PCB; and one or more filters, wherein the sensor package comprises one or more radiation sensors mounted therein, wherein each of the one or more filters filter one or more types of radiation that enter an exposed side of each of the one or more sensors at angle of at least 60 degrees with respect to a respective axial line through respective centers of each of the one or more sensors.

Claims

1. A device comprising:

a printed circuit board (PCB);

a sensor package mounted on a first side of the PCB;

electronics mounted on a second side of the PCB; and

one or more filters,

wherein the sensor package comprises one or more radiation sensors mounted therein,

wherein each of the one or more filters filter one or more types of radiation that enter an exposed side of each of the one or more sensors at angle of at least 60 degrees with respect to a respective axial line through respective centers of each of the one or more sensors.

2. The device of claim 1, wherein the one or more filters are a single filter.

3. The device of claim 1, wherein the one or more filters are two or more filters.

4. The device of claim 1, wherein one or more filters are mounted on an exposed side of the sensor package.

5. The device of claim 1, wherein the one or more filters are spaced from an exposed side of the sensor package.

6. The device of claim 5, wherein the one or more filters are mounted in a filter holder that is mounted on the substrate.

7. The device of claim 6, wherein the one or more filters are mounted in a filter holder that is mounted on the radiation transmissive external case.

8. The device of claim 6, wherein the one or more filters are mounted in a filter holder that is part of the radiation transmissive external case.

9. The device of claim 1, wherein the device comprises a radiation transmissive external case spaced from an exposed side of one filter of the one or more filters.

10. The device of claim 1, wherein the radiation transmissive external case is curved.

11. The device of claim 1, wherein the one or more radiation sensors are a single radiation sensor.

12. The device of claim 1, wherein the one or more radiation sensors are two radiation sensors.
