The Twyman-Green interferometer with LWIR wavelength from 4D Technology is a high-precision optical measuring instrument that is widely used in both science and industry. It measures wavefronts and analyzes optical components to detect even the smallest deviations in the optics. The interferometer thus guarantees consistently high quality.
This makes it an indispensable tool for the optics industry and scientific applications. It delivers outstanding results, especially in combination with LWIR wavelengths (long-wave infrared).
The PhaseCam impresses with its high-resolution sensor and user-friendly control, combined with comprehensive analysis software. Thanks to 4D Technology's patented "Dynamic Interferometry®" technology, the high-speed optical phase sensor enables wavefront measurements in less than 30 microseconds. This speed allows the interferometer to be used under almost all conditions without the need for vibration isolation.
The integrated software "4Sight Focus" facilitates operation and offers a comprehensive solution for measuring telescope optics, large mirrors and optical systems. Particularly noteworthy is the availability of interferometers with LWIR wavelength, which are ideal for special applications in the long-wave infrared range.
Application areas and wavelength options of the interferometer
The interferometer is ideal for measuring large focal optics and optical systems, such as concave telescope mirrors and lens systems. It is also ideal for testing afocal components with a small aperture, such as flat mirrors and collimators. It can also be used to adjust elements such as scanning mirrors. Special, adapted systems are available for measurements in clean room conditions.
As standard, the laser interferometer offers wavelengths of 532 nm and 632.8 nm for the visible range and 1064 nm and 1550 nm for the shortwave infrared range. Options are also available for special applications in the MWIR or even in the longwave infrared range (LWIR) up to 10.6 µm.
