The PhaseCam from 4D Technology is a high-precision Twyman-Green interferometer with NIR wavelength that is widely used in science and industry. It is used both for measuring wavefronts and for analyzing optical components. This allows it to detect even the smallest deviations in the optics, thus always ensuring high quality. This makes this laser interferometer an indispensable tool for the optics industry and science.
The PhaseCam offers a high-resolution sensor and simple manual control. Combined with the full-featured analysis software, it delivers impressive performance. Thanks to the patented “Dynamic Interferometry®” technology from 4D Technology The high-speed phase sensor enables wavefront measurements in less than 30 microseconds. This means that the PhaseCam can be used under almost any conditions without the need for vibration isolation.
The user-friendly "4Sight Focus" software offers an all-round, worry-free package. It makes measuring telescope optics, large mirrors and optical systems much easier. The laser interferometer is versatile because it is suitable 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. In addition, it can also measure adjusting elements such as scanning mirrors.
Interferometer wavelength options
If you want to carry out measurements in clean room conditions, there are specially adapted systems. As standard, this laser interferometer is available with NIR wavelengths of 532 nm and 632.8 nm for the visible range and 1064 nm and 1550 nm for the short-wave infrared range. For special applications, we also offer interferometers with MWIR wavelengths and even options up to 10.6 µm in the long-wave infrared range. This way you can find the right solution for your specific requirements.
