Optical Surfaces offers a variety of standard and custom precision flats manufactured of high-stability materials, such as glass, silica, and Zerodur glass-ceramic, in sizes ranging from 105 mm to 600 ...

Two parallel optical surfaces often exhibit colorful fringes along the lines of equal thickness because of the interference of light. This simple phenomenon allows one to observe subwavelength ...

Topography becomes more important in quality assurance for manufacturing. This regards the characterization of macro-sized to medium optics and the optimization of a manufacturing process using a ...

Primary performance data for passive fiber-optic devices is provided by spectral measurement of optical insertion loss (IL) and polarization-dependent loss (PDL). Often used to characterize optical ...

Optical non-contact profilers are interference microscopes used to accurately measure the three-dimensional height variations on surfaces of a given test material. Optical profilers manipulate the ...

With the continuous advancement of photoelectric performance in major equipment and advanced instruments, traditional optical elements are increasingly inadequate to meet the demands of modern systems ...
