Model 4020 High Performance Dynamic Twyman Green Interferometer

Instantaneous Acquisition Industry Leading Analysis, Standard

The PhaseCam
® 4020 is a compact, lightweight dynamic laser interferometer with simple, manual controls for measurement of optics and optical systems. The industry standard for measuring large, focal optical systems such as concave telescope mirrors and lens systems, the PhaseCam is equally well suited for testing small aperture afocal components such as flat mirrors and colli- mators.The PhaseCam 4020 incorporates patented technology using a single camera, high-speed optical phase sensor that makes a wavefront measurement in less than 30 microseconds—over 5000 times faster than a temporal phase shifting interferometer. Because acquisition time is so short, the PhaseCam can be used under almost any conditions, even for measuring moving parts, without vibration isolation or turbulence control. This insensitivity to environmental factors makes the PhaseCam ideally suited for use on the production floor, in clean rooms and in environ- mental test chambers. It can even measure moving parts such as deformable or scanning mirrors, spinning disks, or vibrating membranes. 4Sight wavefront analysis software features a user-friendly interface with unmatched simplicity, analysis features and graphical displays. The Measurement Console display aids alignment and execution of single, averaged, burst or continuous data acquisition. The Measurement Flow interface lets you visualize the entire measurement data flow, from raw acquisition through masking, reference subtraction, terms removal, etc. The unique Measurement Stack enables complex data manipulation and comparison. Zernike, Seidel, geometric and diffraction analyses are easy to perform. Comprehensive data sharing capabilities let you read, write, save and print from most file types, including MetroPro IDL
® , MatLab
® , Opticode
® ,Vision
® , HDF5
® and CodeV
® . Generating phase movies to characterize deforming surfaces and moving parts is simple and straight- forward.

Accessory Optics

Numerous accessories and options are available including diverger lenses, beam expanders and wavelength options.

Complete Measurement System

The PhaseCam 4020 is a turnkey instrument that includes the interferometer, 4Sight™ advanced wavefront analysis software, and complete, high-speed computer system. Samples with any reflectivity from 1% to 100% can be performed with a simple adjustment. Its stabilized HeNe laser (632.8 nm) provides excellent coherence stability.
