6 Σεπ 2024 · Fly Eye Lens, also known as a micro lens array or micro mirror array, is a type of lens body composed of many small lenses (micro lenses). These small lenses are tightly arranged together, forming an array that mimics the structure of compound eyes in insects, especially flies and other insects, hence the name.
A fly’s eye lens is called a fly’s eye because it is how a fly sees his environment. It is a sheet of plastic embossed with a lens array on the surface. The lens array is not a linear lens array like a lenticular, but round lenses nested together in a honeycomb.
Our fly’s eye condensers arrays are available in 5 and 10mm square configurations, and are designed for flat-top and line generation. The condenser arrays are a monolithic assembly of dual-surface cylindrical microlenses, creating condensers which are completely free of adjustment.
A fly-eye or fly's-eye lens is actually a 2D array of tiny lenses, called lenslets, and are typically used in pairs to spatially transform light from a non-uniform to uniform irradiance distribution at an illumination plane. It gets its name because the appearance is much like a fly's eye.
Fly’s Eye Condenser Arrays: A fly’s eye condenser array, formed of dual-surface cylindrical microlenses mounted in a close-packed configuration, is used for flat-top and line generation. This array is ideal for applications requiring a short working distance and a large illuminated field.
Fly’s eye lens arrays are mostly used in pairs to spatially homogenize or make a light source uniform at the illumination plane. The two arrays are called the ‘objective array’ and the ‘field array’ and are used with a so-called ‘condenser lens’.
A fly’s eye array consists of individual square or rectangular microlenses mounted on a substrate in a close-packed, no-gaps configuration. A typical array will have 7-11 channels in each direction, optically overlapped in the illumination plane.
