Interferometers
Highest precision for every measurement task
Interferometer VI-direct
The 6th generation interferometer VI direct works according to the functional principle of a Fizeau interferometer. They are available with different test diameters: 10, 16, 28, 50 or 100 mm. The size depends on the chosen objective tube. A test diameter of up to 150 mm is also possible using an expanding lens. The interferometers of the VI-direct series are a cost-effective alternative to conventional interferometers and are very adaptable to customer-specific arrangements. The product offers the possibility of vertical and horizontal use position as well as oblique angle application.

Micro-Interferometer VI-direct
The Micro-Interferometer VI-direct extends the range of flatness testing to the domain of smallest diameters. The Fizeau-type interferometer is able to measure the surface flatness of optical parts with a diameter between approx. 0.8 mm to 3.6 mm. The cost effective Micro-Interferometer VI-direct can be used for testing of optical parts like micro-prisms, laser crystals, fiber endings etc..

Software INTOMATIK-S
The INTOMATIK-S software uses the static fringe evaluation method for calculating the surface shape deviation and is thus almost free of influences due to air turbulence or vibrations. However, the fringe evaluation does not achieve the same accuracy as the phase shift algorithm of the INTOMATIK-N software and also cannot automatically determine the sign of the surface shape deviation.

Software INTOMATIK-N
Due to the phase shifting algorithm the software INTOMATIK-N offers higher accuracy and a larger measuring range with respect to surface form deviations in comparison to the INTOMATIK-S. Additionally the sign of the surface form deviation is automatically determined.
