Zygo PTI 250
PTI 250 - Small aperture Fizeau interferometer for surface form measurement
|
The PTI 250™ line is a family of 25-mm aperture interferometers that provide full 3D surface and wavefront maps, and radius of curvature measurements, of lenses and lens systems. These systems are Fizeau interferometers and are designed and built using the same successful methods as ZYGO's widely used GPI™ and VeriFire™ interferometer systems. PTI 250 systems feature proven ZYGO measurement technology and are reliable, easy to use, and an excellent return on your investment. They are equally well suited for process control in high-volume production, or demanding research in an R&D lab. |

Using Zygo’s Flashphase acquisition mode measurements can be made in environments with vibration and air turbulence. This makes the PTI 250 an ideal metrology tool for manufacturing environments. Click here to go to PTI 250 Interferometer Models |
Measurements
Industry areas
Whether for research or manufacturing the PTI 250 provides accurate and reliable control of optical surfaces and radii. Measurement of optics for DVD players, mobile phones, CD-ROM, endoscopes, digital cameras, laser optics and contact lens moulds are all easily taken in seconds by one of the PTI 250 models. The PTI 250’s quick and easy operation coupled with repeatable, reproducible and accurate results makes it an ideal metrology instrument for monitoring flatness of super finished metal parts such as diesel fuel injectors components.
