Edmund Optics

Correction or modulation of the wavefront to enhance contrast in imaging systems, to generate specific focal geometries, and to reconstruct high-resolution 3D images in high-resolution microscopy.

Optical elementspdf

Wave-optical consideration of the structural properties produces higher flexibility in the addressed intensity angle spectrum and allows the generation of almost any angular distribution.

Optical elementsmeaning

Highly specific and controlled intensity distribution (symmetric and asymmetric) with maximum efficiency and low scattered light for partial, incoherent, monochromatic or white light. Micro-optical diffusers optimize your LED and laser lighting applications.

The smooth surface without cracks of the optical elements combined with an optimized optics design, which takes the input conditions into account, leads to a very high optical efficiency (90%), which can be increased with an adapted anti-reflective coating.

Beam homogenization for any incoming beam geometry with high homogeneity and high efficiency for a wide range of wavelengths (for white light, if applicable). Microlens arrays enable highly efficient applications in LED and laser lighting.

Opticalcomponents examples

Beam transformation with customized optical distribution (without speckle generation) of a defined incident beam profile of arbitrary quality.

Refractive optical elements that exhibit minimal structural resolution yet have a numerical aperture of up to 0.7 and efficiency approaching 100% can be fabricated using economical lithographic methods.

The refractive optical elements do not contain any cracks and show a refractive mode of action. Unlike diffractive optical elements, the refractive optical elements with their "smooth" surface profile shapes produce higher efficiency with no zero diffraction order.

Refractive optical elements (ROEs) refract light thanks to microstructured surfaces and functionally resemble familiar conventional lenses and prisms. Thanks to the extreme miniaturization of corresponding functionalities of refractive macro optics, ROE enable very compact, lightweight and elegant, optical solutions.

Refractive micro-optical elements miniaturize well-known conventional macro-optics. The functional definition is largely based on their surface topography profile. The asymmetrical profiles have flexible and high optical functionalities. They are combined with a high level of efficiency, a wide angular spectrum and a high degree of homogeneity.

The refractive optical elements do not contain any cracks and show refractive property, which is very suitable from polychromatic to achromatic applications. Unlike diffractive optical elements, the refractive optical elements with their "smooth" surface profile shapes produce higher efficiency with no zero diffraction order.
