WebWhen a pair of fly’s eye arrays is used in combination with a condenser lens they can provide uniform irradiance at the illumination plane. When set up in this configuration the first array is called the objective array, and the second the field array.

WebA condenser is an optical device which is used for conditioning illumination light, for example in an optical microscope or an image projector. Typically, it contains one or more lenses and a diaphragm . Even multi-lens … 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 …
WebA condenser microscope is one that illuminates specimen samples from beneath, shining light through it and into the objective lens for viewing. The condenser itself is a focusing lens that sits between the light source and the underside of the sample, and it acts to focus this diffused light to illuminate the sample so it can be viewed clearly ...

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. The first fly’s … See more small wire electrical connectorsWebLens array arrangements are commonly used for the beam shaping of almost arbitrary input intensity distributions into a top-hat. The setup usually consists of a Fourier lens and two identical regular microlens arrays - often referred to as tandem lens array - where the second one is placed in the focal plane of the first microlenses.
