AccuFiz IR Interferometers New AccuFiz® IR laser interferometers operate at wavelengths of 3.8 μm (MWIR) and 10.6 μm (LWIR), for accurate measurement of polished or rough-ground optics and metal surfaces. AccuFiz systems are ideal for measuring concave, convex and afocal IR components, as well as IR telescopes and lens systems. Their ability to capture high slopes makes it possible to measure aspherical optics without the need for a holographic element. Optional, vibration-insensitive Dynamic Mode enables measurements under almost any environmental condition, without vibration isolation.

UV and IR Interferometers Optical applications are broad and varied. Testing at design wavelength is critical for final alignment and system qualification. Lithographic, DVD, and Infrared imaging lenses all require testing at design wavelength and represent broadly-varying wavelength requirements.

PhaseCam IR - Infrared Laser Interferometers PhaseCam IR systems employ Dynamic Interferometry® to acquire measurement data in less than 1 millisecond. Because acquisition time is so short, the instruments can measure accurately despite vibration and air turbulence. The systems can be used in demanding environments such as clean rooms or the production floor. These dual-mode systems can also operate using traditional, temporal phase-shifting.

PhaseCam NIR - Near Infrared Laser Interferometers Each PhaseCam laser interferometer employs Dynamic Interferometry® technology to acquire measurement data in less than 30 microseconds. Because acquisition time is so short, the instruments are insensitive to vibration and air turbulence, enabling use in difficult environments such as production floors, clean rooms and environmental testing chambers. Beam Ratio adjustment ensures maximum fringe contrast, enabling measurement of optics with reflectivity from 1 – 100%.

Turbo FT - FT-IR/NIR Spectrometer The Turbo FT is a patented, rotary scan interferometer which can achieve scan rates of 10-1000 scans per second. Also, due to its smooth, continuous scan, it can be run without the laser reference channel normally required in an FT-IR spectrometer. Its small size, ruggedness, speed, and very low power requirements make it an ideal candidate for high vibration environments both in the lab and out in the field. 

4D Custom Solutions 4D's Custom Solutions program lets you tap the creativity and expertise of our team to solve your metrology challenges. 4D custom interferometers and laser interferometers overcome difficult environments, complex setups and one-of-a-kind measurement problems, at wavelengths from DUV through IR.

VERTEX 80/80v - spectrometers The VERTEX 80 and the VERTEX 80v vacuum FT-IR spectrometers are based on the actively aligned UltraScan™ interferometer, which provides PEAK spectral resolution. The precise linear air bearing scanner and PEAK quality optics guarantees the ultimate sensitivity and stability. The VERTEX 80v is an evacuated optics bench that can eliminate atmospheric moisture absorptions for ultimate sensitivity and stability; enabling demanding experiments such as high resolution, ultra fast rapidscan, step-scan, or UV spectral range measurements.
