Metrology

OGP SmartscopesSmartscopes from Optical Gaging Products (OGP) are multisensory metrology platforms used for making dimensional measurements of optics.
Nikon 6D AutocollimatorsAutocollimators are optical instruments used to make non-contact measurements of angles. They are often used to measure the accuracy of prism angles.
Fujinan 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^® 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.
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.
DigiMicro Microscopes Microscopes are used to determine the surface quality of optics.
Olympus MX51 Microscopes Microscopes are used to determine the surface quality of optics.
