Zygo^® VeriFire™ High Resolution InterferometersInterferometers are instruments used to measure small displacements, refractive index changes, and surface irregularities. They split light from a single source into two separate beams that travel different optical paths before recombining. Interference fringes are then formed, which provides information on the difference in optical path length between the two paths. Interferometers are often used to measure the surface accuracy of optics.
Zygo NewView White Light InterferometersInterferometers are instruments used to measure small displacements, refractive index changes, and surface irregularities. They split light from a single source into two separate beams that travel different optical paths before recombining. Interference fringes are then formed, which provides information on the difference in optical path length between the two paths. Interferometers are often used to measure the surface accuracy of optics.
Zygo^® GPI 4” Aperture Vertical and Horizontal InterferometersInterferometers are instruments used to measure small displacements, refractive index changes, and surface irregularities. They split light from a single source into two separate beams that travel different optical paths before recombining. Interference fringes are then formed, which provides information on the difference in optical path length between the two paths. Interferometers are often used to measure the surface accuracy of optics.
Xonox InterferometersInterferometers are instruments used to measure small displacements, refractive index changes, and surface irregularities. They split light from a single source into two separate beams that travel different optical paths before recombining. Interference fringes are then formed, which provides information on the difference in optical path length between the two paths. Interferometers are often used to measure the surface accuracy of optics.
Spherometers Spherometers are instruments used for the precise measurement of the radius of curvature of a sphere or a curved surface, such as the surface of a lens., CalipersCalipers are tools used to measure the distance between opposite sides of an object and are used for dimensional measurements of optics. , Dial IndicatorsDial indicators accurately measure small distances and angles and are used for dimensional measurements of optics.
TRIOPTICS Opticentric^® Centration Measurement MachinesCentration Measurement Machines are used to measure the misalignment between the mechanical and optical axes of lenses.
Zeiss Contura G2 CMMsCMMs, or coordinate measuring machines, are instruments used for measuring the physical dimensions of optics. They can be computer controlled or manually operated.
Olympus MX51 Microscopes Microscopes are used to determine the surface quality of optics.
Brysen Rev R Scratch-Dig SetsScratch-dig sets are reference pieces of glass used to determine the surface quality of optics following the U.S. Standard MIL-PRF-13830B.
