Claim 7:
8. A method for detecting foreign materials comprising the steps of:
a) providing a system for detecting foreign materials comprising:
an alternative light source (ALS);
one or more filters operationally associated with the ALS;
one or more camera lenses operationally associated with the ALS and the filters;
one or more processors, a computer readable memory, and a computer readable storage medium operatively associated with a computing device operatively associated with the ALS;
one or more sensors operationally associated with the computing device and the ALS, wherein the sensors detect the presence of the filter;
a filter holder operationally associated with the ALS and the filter; and
a lens step ring including one or more magnets operationally associated with the ALS and the filter;
wherein the lens step ring releasably secures the filter to the ALS;
wherein the one or more sensors detects the presence of the one or more filters when they are secured to the filter holder; and
wherein the sensor activates programming instructions to change the wavelength of light generated by the ALS based on the filter detected:

a camera operationally associated with the lens and the computing device;

b) activating white light LEDS on the ALS;
c) securing one or more filter to the ALS;
d) detecting the presence of the filter using the one or more sensors;
e) deactivating the white light LEDs on the ALS;
f) activating blue light LEDS on the ALS;
g) directing light from the ALS onto a subject or object being examined;
h) locating the foreign materials on the subject or object being examined; and
i) capturing one or more images of the foreign materials with the camera.
