WebA simple two-lens Abbe condenser is illustrated in Figure 1. In this figure, light from the microscope illumination source passes through the condenser aperture diaphragm, located at the base of the condenser, and is concentrated by internal lens elements, which then project light through the specimen in parallel bundles from every azimuth.The size and … When setting up the design, the user needs to decide how many channels to have in the vertical and horizontal directions in the array. The larger the number of channels, the more uniform the illumination at the illumination plane. However, the edges between the lenslets are not infinitely sharp, and so light gets … See more In digital projector design, we want to ensure that the digital source matches the projected image when it comes to the irradiance profile. This constraint therefore requires a projector … See more A fly’s eye array is a two-dimensional array of individual optical elements assembled into a single optical element. It is used to spatially transform light from a nonuniform … See more The following is a simple example of a real fly's eye illumination system for digital projector use. This sample file can be found in … See more Fly’s eye arrays are typically used in pairs along with a condenser lens to provide uniform irradiance at the illumination plane.
