Precision optical components - Import export

With the chip-removing microstructuring of metal surfaces, LT Ultra offers the right manufacturing technology for the production of embossing tools with optical surface qualities that allow economical replication in large numbers. Examples of microstructuring are the production of microfluidics or microlenses on our ultra-precise multi-axis machines. We can manufacture the structures directly in various materials such as brass, chemically deposited nickel or in selected hardened steels.For the replicating production of optical components, ultra-precise mold inserts made of steel are of particular interest due to their very long service life compared to other materials. In order to avoid the final polishing, which often leads to an undesirable change in shape or which is impossible due to a high structure density, LT Ultra offers ultrasound-assisted machining of steels with geometrically defined cutting edges made of monocrystalline diamond.

In the basic version the MMC 5000 consists of a main X-axis featuring a linear air bearing (feed axis), a linear roller bearing Z-axis (infeed axis) and the milling spindle (air bearing) mounted on top of the Z-axis. The main application is face milling of optical and mechanical precision components. A Y-axis is available as an option. Another useful accessory is a second milling spindle, used perpendicular to the first one, thus allowing for the machining of two sides of a workpiece to perpendicularity in one setup. Accessories, like vacuum chucks, different milling spindles, touch probes for part thickness measurement, machine interferometers and other sensors for insitu measurement of workpiece shape and roughness, make the MMC 5000 machines an effective tool. In addition, various sensors are available for measuring of the workpiece geometry and surface quality during the manufacturing process.

The MMC 600/900 is the basis for a series of machines that, via several accessories and options, can be fully customized to individual needs. In the basic version the machine consists of a main X-axis featuring a linear air bearing (feed axis), a linear roller bearing Z-axis (infeed axis) and the milling spindle (air bearing) mounted on top of the Z-axis. The main application is face milling of optical and mechanical precision components. Several accessories like a Y-axis, an A-axis and/or C-axis are available, thus expanding the range of machinable parts to
microstructures, lenticular structures, spheres, polygons and so on. Accessories, like vacuum chucks, different milling spindles, touch probes for part thickness measurement and even machine interferometers for insitu measurement of workpiece shape, make the MMC 600 and 900 machines an effective tool. Besides further accessories, there is the possibility to make customized solutions, to adapt the machine to your needs.

Edmund Optics features the world’s largest inventory of off-the-shelf Optical Components, including a wide selection of Optical Lenses, Optical Filters, Optical Mirrors, Windows, Prisms, Beamsplitters, or Diffraction Gratings. Optical Lenses are designed for focusing or diverging lighting. Optical Filters are used to selectively pass or block a specific wavelength or wavelength range. Optical Mirrors, Prisms, or Beamsplitters split or alter the path of light. Windows are used to protect sensitive components such as electronic detectors or sensors from outside environments.

ORAFOL Fresnel Optics GmbH offers a wide variety of microstructured optical components in varios sizes. Among others fresnel prisms, cylindrical lenses and beamsplitters, lenticular lenses and corner cube reflectors. We provide both a catalogue of standard products that can be adapted to our customers' requirements as well as the capabilities to design and manufacture custom optical solutions including finishing processes e.g. anti-reflective coatings and nano-structures and precise CNC machining.

The best known microstructured optic is the Fresnel lens. Compared to a standard lens the surface of the fresnel lens is divided into a number of concentric grooves allowing for a wide range of optical effects (e.g. high-aperture (fast) large-area) while also reducing thickness, weight and cost. Fresnel lenses can be designed as a collimator, collector or with finite conjugates. They are usually corrected for spherical aberration. We offer a variety of standard designs as well as custom designs for our customers. Our lenses can be finished with a range of optical coatings and nanostructures and will be trimmed precisely to our customers requirements.
