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.

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.

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.

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.

Adaptive optics is a special form of high-performance laser mirrors. Their characteristic is that the mirror surface is designed as a membrane, which can be deformed in a controlled manner by pressure change on its back. The shape errors occurring in this case are extremely low; we tolerate them with a maximum of 0.0005 mm. Our adaptive optics are suitable for use with laser power up to 10 KW thanks to integrated direct water cooling and HR coating. Most common types are the adaptive optics with elliptical membrane as these can be used directly to the 90 ° deflection. They are identical to our standard planes of identical aperture and therefore do not need special housings. In addition to the elliptical varieties, LT Ultra also offers round adaptive mirrors. As a rule, these replace the concave spherical mirror of an existing telescopic beam expander directly at the resonator. Round adaptive mirrors can only be used with deflections <10 °. …
