ZYGO serves Semiconductor, Industrial and Research customers by providing non-traditional glass and low-expansion components and systems which fall outside of the traditional definition of “optics”. Examples include light-weighted wafer stages for semiconductor lithography, zero-expansion metrology reference frames for precision positioning control, and traditional straight-edge mirrors and references. We routinely manufacture these items in sizes up to 1.25m with nanometer precision...

ZYGO's Optics business segment manufactures precision spheres and lenses ranging in diameter from 50mm to 700mm with radii from 12.7mm to 8metres. Their standard product line of transmission spheres is available in 100 and 150mm clear apertures ranging in f-numbers from f/.65 to f/11 with wavefront errors of λ/10 or λ/20. The new line of Ultrasphere™ transmission spheres is available...

Modern Defense, Aerospace and NewSpace customers require high performance optical systems which minimize Size, Weight and Power (SWaP) while maximizing optical performance. One proven technique for achieving demanding SWaP requirements is to require light-weighted optics. Light-weighting is a process by which material is removed from the optical component by machining or other methods while preserving the optical performance. This is...

ZYGO manufactures the world’s most accurate aspherical, spherical and freeform optics. These can be manufactured in sizes up to 600 mm, with surface figure tolerances better than 100 picometers. To put this into perspective, imagine an optic the size of the Unites States with a surface accuracy of less than a millimeter!  Extreme precision powered surfaces: Many geometries in sizes...

Join us as we uncover the importance of this...

In this study, an ambient–spark–produced–Au– nanoparticle–laden nitrogen gas was mixed with an atomized solution of 1–hexanethiol and ethanol (EtOH). By increasing the thiol concentration from 0.1% to 1.0% (v/v), the size distribution of merged particles (Au–thiol) was changed from bimodal to unimodal configuration. The latter phenomenon is attributed to quantitative incorporation of Au nanoparticles into atomized particles. Measurements of cell...

Researchers have reported the observation of long-lived Floquet prethermal states in a bulk solid composed of dipolar-coupled 13C nuclei in diamond at room temperature. For precessing nuclear spins prepared in an initial transverse state, we demonstrate pulsed spin-lock Floquet control that prevents their decay over multiple-minute long periods. Researchers observed Floquet prethermal lifetimes 𝑇’2 ≈90.9s, extended >60,000-fold over the nuclear...

BackgroundRADAR (“Radio Detection And Ranging”) is a system that uses electromagnetic waves to identify an object, its direction, relative speed, or even for 2D & 3D imaging. Radars help identify both fixed & moving objects such as aircraft, ships, vehicles, weather formations, and terrain. Radars use transmitters that emit electromagnetic waves that are reflected by a target (“Echoes”) and detected...
