Raster-scanning polygons: We manufacture polygons having arbitrary pyramidal angles. We can also machine varying pyramidal angles on individual polygons.

LT Ultra has also implemented the technology of metal-cutting microstructuring in roller lathes. We can offer the production of structures in a grid between 5 and 150 µm in optical quality for provided rollers.Offer up to a length of 2500 mm, a diameter of up to 800 mm and a maximum weight of 2500 kg.

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.

LT Ultra is your partner for the production of optical surface qualities in injection mold inserts. For example, we can manufacture inserts for the injection molding of spectacle lenses with several focal lengths as well as mold inserts for microlenses or components for vehicle lighting systems. In addition to simple geometries such as spheres or aspheres, we mainly manufacture non-rotationally symmetrical components and freeform surfaces.Mold inserts for a long service life can be made from chemically deposited nickel (NiP). Here you can work directly in the nickel. The advantage is that the very durable nickel can also be deposited on substrates that could not be brought into optical quality themselves or only with great effort. On request, LT Ultra offers the complete delivery of the mold insert as well as the processing of additional parts.

Structured optics are produced using turning, milling and planing Technology.. Under thermally controlled conditions we can realize structure depths in the submicrometer range with accuracies also in the submicrometer range. Different types: Microlenses, Grids, Fresnel- optics.

UP milled parts are components that due to their geometric shape can only be produced with 4- or 5-axis machines with high-frequency spindle. The MM machines, developed by LT Ultra, make it possible to produce the parts economically and quickly.

Three-axes turning technology – Our advanced, three-axes turning technology allows us to turn optics having any symmetric geometric shape. An extensive range of sophisticated diamond-cutting technologies is available, for single piece as well as for series production.

Continuously improving production, keeping defect rates low, and fulfilling customer requests in order to stay competitive can be very challenging. Leica has developed the S9 stereo microscope series to help you cope with these challenges. With this new generation of Greenough stereo microscopes operators will be able to reveal details faster as they spend less time having to adjust the microscope. Available in different versions for diverse needs the S9 stereo microscopes boost efficiency and optimize optical inspections in your production line or Quality Control division, due to: - FusionOptics technology with 12 mm depth of field to find details fast - High magnification up to 55x and 9:1 zoom for quick changes from overview to details - 122 mm working distance for easy sample manipulations under the microscope - Integrated, network-camera for easy image sharing

Oxidation, chemical and temperature resistant lubricating and sealing agent for the precision engineering, optic and electronic sector.

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.

Optical sensors function contactlessly. They detect objects independent of their characteristics (e.g., shape, color, surface structure, material). The basic operating principle is based on the transmission and reception of light. There are three different versions: 1. The through-beam sensor consists of two separate devices, a transmitter and a receiver that are aligned with one another. If the light beam between the two devices is interrupted, the switching output integrated in the receiver changes its status. 2. With the retro-reflective sensor, the transmitter and receiver are located in one device. The emitted light beam is reflected back to the receiver by a reflector that is to be mounted opposite the device. As soon as the light beam is interrupted, the switching output integrated in the device changes its status. 3. With the diffuse reflection sensor, the transmitter and receiver are in one device. The emitted light beam is reflected by the object that is to be detected.

Knight Optical supply stock and custom deviation penta prisms that cover the visual and NIR range. Deviation prisms are an optical component that will redirect a light beam into another known angle relative to the incoming beam. The penta-prism is a deviation prism which is used in cameras with a movable mirror that bends the beam vertical onto the focus graticule. The penta-prism provides a 90° deviation of the beam from the focus plane and, via an eyepiece, the user can aim the camera along the same axis as the beam that is focused onto the detector, electronic or wet film. Deviations through other angles can be accomplished using, for example, abbe constant deviation, littrow, and wadsworth prisms. Read PDF for more info

Knight Optical can offer UV Fused Silica Windows for Vacuum Applications. UV Fused Silica is a relatively hard optical glass with a very low coefficient of thermal expansion. This means that it is a good choice for us in Vacuum applications, as any difference in temperature will not affect the optical performance. In addition to the above, UV FS has high transmission from UV to NIR meaning that there is little loss of image when it is used for a Vacuum Window/viewport and therefore the quality of the optical system is not compromised. All our UV Fused Silica Lenses are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Trioptics Optispheric, and Starrett AV300 and Zygo Verifire XPZ. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components Read PDF for more info
