High accuracy non-intrusive fertility choice device for women, using polarized light

A high accuracy, non intrusive fertility monitor for determining the fertility of women comprising:

• a hand held housing having a top and a bottom,
• a flat optical specimen glass insertable into the top of said housing,
• an eyepiece located at said top of said housing for viewing the specimen glass,
• a light source at the bottom of the housing,
• polarizing elements located between said light source and said specimen glass for polarizing the light before it reaches said specimen glass and consisting of a polarizing filter, an optical delay plate, and a spectral rotating sheet, and an analizing filter between the specimen glass and said eyepiece,
• wherein the polarized light provides improved optical analysis of estrogen crystals of dried saliva once placed on the specimen glass by making the crystals visible and shining on a black background for better determination of fertility.
