Abstract

A light source for testing sites using a fluorescent dye is described. The light source can include a low voltage lamp or a low heat generating lamp. An emission from the fluorescent dye can be detected through a filter lens, which can include a primary filter and a trim filter. The filter lens can transmit the emission from the fluorescent dye and substantially block an excitation wavelength. The emission from the fluorescence dye is detected through a filter lens including a primary filter and a trim filter, through which the emission wavelength is transmitted, but the excitation wavelength is substantially blocked.

Claims

1. A system for examination of a substance which emits light at a wavelength greater than a wavelength of light emitted from the light source when the substance is excited by the wavelength of light emitted from the light source, the light source comprising:

a light source comprising;

a housing having a light outlet; and

a low voltage lamp oriented to emit light through the light outlet, the light source emitting an excitation wavelength of light; and

a filter lens through which emission of light from a substance when the substance is excited by excitation wavelength of light, the filter lens including a primary filter and a trim filter through which the emission wavelength can be detected and the excitation wavelengths of light is substantially blocked and wherein the filter lens is a portion of eyewear.

2. The system of claim 1, wherein the trim filter substantially blocks transmission of wavelengths that compete with detection of the emission wavelength from the excited substance.

3. The system of claim 1, wherein the trim filter substantially blocks a set of wavelengths different from the wavelengths blocked by the primary filter.

4. The system of claim 1, wherein the light source emits light of wavelengths up to 700 nm.

5. The system of claim 1, wherein the primary filter substantially blocks light in the range of 720 to 850 nm.

6. The system of claim 1, wherein the trim filter substantially blocks light from 650 to 850 nm.

7. The system of claim 1, wherein the primary filter includes a rose colored dye.

8. The system of claim 7, wherein the trim filter includes a blue colored dye.

9. The system of claim 1, wherein the low voltage lamp includes a light emitting diode.

10. The system of claim 1, wherein the lamp is powered by a battery.

11. A method of testing a system containing a substance capable of emitting an emission wavelength of light after being excited by an excitation wavelength of light, the method comprising:

providing an excitation wavelength of light from a light source to a test site; and

detecting transmission of light through a filter lens including a primary filter and a trim filter through which the emission wavelength can be detected and the excitation wavelengths of light is substantially blocked wherein the filter lens is a portion of eyewear.

12. The method of claim 11, wherein the trim filter substantially blocks transmission of wavelengths that compete with detection of the emission wavelength from the excited substance.

13. The method of claim 11, wherein the trim filter blocks a set of wavelengths different from the wavelengths blocked by the primary filter.

14. The method of claim 11, wherein the light source emits light of wavelengths up to 700 nm.

15. The method of claim 11, wherein the primary filter blocks light in the range of 720 to 850 nm.

16. The method of claim 11, wherein the trim filter blocks light from 650 to 850 nm.

17. The method of claim 11, wherein the primary filter includes a rose colored dye.

18. The method of claim 17, wherein the trim filter includes a blue colored dye.

19. The method of claim 11, wherein the low voltage lamp includes a light emitting diode.
