Key Features Test transmitted wavefront quality of aspheric DVD pick-up lenses. 405 nm light source tests DVD lenses at their operating wavelength. Circular, horizontal, or vertical beam polarization for testing birefringent samples. May be used in upward-looking or horizontal configuration. Quantitative phase measurement and analysis of surface quality and transmitted wavefront quality.
Compact footprint integrates easily into any work space.
Based on proven, patented, designs - from the authority in interferometry. System accuracy for relative testing is dependent on the quality of the reference optic. 2 Precision is the residual rms error of the difference of two consecutive measurements, each with 16 phase averages. This specification is derived from 100 measurements and represents the mean value plus 2 sigma. 3 Repeatability of the quoted statistic is for 100 measurements of the same part, with 16 phase averages per data set.
