Alignment of the microscope body with the condenser is accomplished by placing a stage micrometer on the mechanical stage and adjusting the clamp position until the micrometer is in sharp focus throughout the viewfield. A ring stand with a three-fingered clamp is used to secure the QX3 body in place. Removal of the Nikon microscope nosepiece housing was necessary in order to obtain room for mounting the QX3 body directly above the substage condenser in the center of the optical pathway. These images were recorded with and without an Abbe-style substage condenser.Īchromatic Condenser Systems - This configuration employs a Nikon Microphot SA stand with an internal tungsten-halide light source and achromatic substage condenser in place of the QX3 stand with its tungsten bulb and mixing chamber. Rheinberg Illumination - By employing colored gels in a reflected light microscopy configuration similar to that for darkfield microscopy, we have been able to simulate Rheinberg illumination. Oblique Transmitted (Hoffman) Illumination - The technique known as oblique transmitted illumination uses direct light from a single azimuth of the condenser light cone to allow illumination of the specimen from one side only. These images were recorded with and without a Nikon substage condenser. Polarized Light - A comparison of images, with and without an Abbe substage condenser, recorded in transmitted brightfield mode equipped with crossed polarizers and a full-wave retardation plate.ĭarkfield Illumination - We have developed a modified form of darkfield illumination that relies on reflected illumination of miniature specimens placed against a dark background.

They can be added, at relatively low cost, to the optical train of the QX3 when both the body and the high performance condenser are mounted together using ring stands and clamps, which are available at science supply houses. High performance condensers can be purchased from microscope manufacturers or through optical supply houses.

This gallery was constructed to highlight the best images that we have recorded using advanced condenser systems with this incredible toy microscope. Our investigations with the Intel Play QX3 computer microscope have resulted in the collection of a large number of digital images of a variety of specimens.
