Newport Corporation offers a wide selection of holographic gratings with varying modulation depths. Generated optically, holographic gratings display none of the periodic errors or ghosts typically found in ruled gratings. Products typically exhibit excellent wavefront flatness and can have high efficiency in a single plane of polarization. (read more)

PhaseCam dynamic Twyman-Green interferometers provide high resolution measurements that are insensitive to vibration and air turbulence. PhaseCams capture full wavefront measurements in as little as 30 microseconds—5000 times faster than conventional phase shifting interferometers. (read more)

PhaseCam® NIR dynamic laser interferometers accurately measure surface shape and wavefront quality at 1.053, 1.064, 1.3 and 1.55 micron wavelengths. PhaseCam laser interferometers acquire measurement data in less than 30 us, making them insensitive to vibration and air turbulence. Applications include measurement of optics for astronomy, surveillance, guidance and directed energy. (read more)

Ondax's PowerLocker™ is ideal for increasing the brightness of high power laser diodes and locking their emission wavelength. The short external cavity enabled by the PowerLocker™ provides better mode selection than systems based on Littrow and Littman cavities. (read more)

The FizCam 2000 Fizeau interferometer combines vibration tolerance, instantaneous phase measurement, the ability to isolate surfaces, and the ability to measure remote and solid cavities, for highly accurate characterization of telescope optics, general-purpose optics and prisms. (read more)

The WaveCam 1000 is designed to test the next generation of CD, Blu-ray and DVD pickup heads. The WaveCam incorporates a single frame, dynamic phase sensor that makes measurements in tens of microseconds and works equally well with pulsed or CW sources. (read more)

The FizCam 3000 is an entirely new Fizeau design, providing highly accurate measurement of optical grade surfaces even in the presence of vibration and air turbulence. Its completely on-axis design eliminates the inherent aberrations, software corrections and painstaking calibrations and alignments typical of tilted beam Fizeau systems. (read more)

The SpeckleCam Electronic Speckle Pattern Interferometer (ESPI) measures the change in shape of structures with diffuse surfaces. Its patented, single camera pixelated sensor enables high spatial sampling. (read more)

The DiskCam 2000 dynamic Fizeau interferometer provides high accuracy measurement of polished aluminum and glass disks/ media, even in the presence of vibration and air turbulence. Featuring a proprietary laser source, the system enables measurement of both sides of uncoated glass disks in a single setup, without the need for extraneous coatings to control multiple interference fringes.
