1. A system for detecting light, the system comprising:

  • a compartment having a body defining an interior wherein the body has an interior surface and a length defined between a first end and a second end of the compartment;

    a wall at the first end of the compartment wherein the wall abuts the body of the compartment;

    a first lens attached to the wall wherein the first lens is located within the interior of the compartment wherein the lens is spherically shaped;

    a light source connected to the wall of the compartment wherein the light source emits light into the interior of the compartment wherein the interior surface of the compartment absorbs an amount of the light emitted from the light source; and

    a sensor connected to the wall of the compartment wherein the sensor detects an intensity of emitted light within the interior of the compartment via the first lens wherein the intensity of emitted light corresponds to the amount of the light which is absorbed by the interior surface of the compartment and further wherein the first lens is located between the sensor and the interior of the compartment.
