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 ...

Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.220024 considers a precise measurement technology of optical coherent structure of random lights. Optical manipulation and ...

A laser Doppler vibrometer’s (LDV) real-time capability enables measurement times roughly six orders of magnitude smaller compared to any method that is based on strobe techniques or provides a ...
