Fly eye lens vs condencer
WebNormally, fly’s eye condensers are used to homogenize light. However, in the case of fully coherent light, a fly’s eye condenser, in connection with some simple optical elements, such as a diffractive axicon, a grating, and a telescope, can be used as a quite flexible beam shaping system, forming arrays of rings, parts of rings, or other structures with varying … WebFly's eye condensers are commonly used for the beam shaping of an arbitrary input intensity distribution into a top hat.

The only time it may not be safe to fly is if you have had retina surgery and have a gas or air … 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. Factory Standard Diameter: +0, -0.1mm; Surface accuracy: λ/2 @633nm or better
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 ... WebA fly's eye condenser (15) for converting an input light distribution into an output light distribution has at least one raster arrangement of optical groups (21, 22), of which at least some comprise means (30) suitable for changing polarization. The fly's eye condenser thus permits specific, location-dependent control of the polarization state of the output light …
