The high-precision surfaceCONTROL 3D 3500 snapshot sensor is used for automated optical inspection of geometry, shape and surfaces on diffusely reflecting surfaces. The surfaceCONTROL 3D 3500 is characterized by its compact design and high measurement accuracy combined with high speed data processing. With a z-axis repeatability of up to 0.4 µm, the sensor sets new standards in high-precision inline 3D measurement technology. It reliably detects the smallest flatness deviations and height differences. Two models cover different measuring fields.

We manufacture a large number of standard products as well as customer-specific special parts with optical surface qualities as contract manufacturing. You are welcome to get an overview in the category metal optics.You can also download all metal optics directly from our general overview or find them in our download area .In addition to such components with an optical function, we also manufacture precision parts for which a high geometric accuracy is in the foreground, such as air bearing components or micro-milled parts. With an extensive inventory of ultra-precision machines and the corresponding measuring technology, we manufacture with accuracies down to the sub-micrometer range and with roughness up to approx. 1 nm [Ra]. LT Ultra serves both single and series production. We look forward to your inquiry.

ZYGO nano-position sensors are widely used in closed-loop motion control systems like photolithography and semiconductor inspection tool stages, as well as for deformable optical systems. We have pioneered innovations in the displacement and position sensors for over 30 years, and we work closely with applications requiring the highest precision and reliability. Our team of applications experts is ready and able to help you tackle your position metrology needs. Displacement Position Sensors ZYGO's ZMI™ systems use heterodyne interferometer technology to precisely measure relative changes in position. Absolute Position Sensors ZYGO'S ZPS™ system uses ultra-compact non-contact optical sensors to measure absolute position over a range of 1.2 mm on up to 64 synchronized channels.
