1. A microscope slide for increasing epifluorescent optical contrast of a fluorescently tagged sample emitting an emission light upon illumination by an excitation light, comprising:

  • a top surface; and

    a bottom surface;

    a sample-proximal infrared reflecting film deposited on said top surface, wherein the infrared reflecting film at least partially reflects an infrared focusing light beam at or near a sample focal point or focal plane; and

    a dichroic reflecting film deposited on either said top surface, adjacent to, or in contact with, the sample, or said bottom surface, underneath the sample, wherein said dichroic reflecting film reflects the emission light emitted by said sample while transmitting the excitation light illuminating said sample.
