Interferometer
S100|HR
CNC polishing puts new demands on metrology tools. Many of these optics are aspheric with tight tolerances. The new machines can produce almost any surface and require a new level of metrology to provide feedback to the polishing process. This just cannot be done with outdated interferometers designed over 30 years ago. The S100|HR has the performance it takes, without breaking the bank. Measure 10X higher fringe densities to enable final figuring to begin sooner, saving you time and money. Plus measure these high density fringes 5X more accurately to enable large polishing corrections that converge quickly to final figure, including aspheres.

40Gb/s DQPSK Receiver
The integrated DQPSK receiver incorporates an optical phase demodulator (delay-line interferometer or DLI) with 2 pairs of balanced photo-diodes and 2 linear TIAs into a single butterfly package. Compared with the currently available discrete solution in which a separate DLI and a separate receiver are used, the integrated DQPSK receiver eliminates labor intensive fiber routing and coupling (between the DLI and the balanced receiver) as well as the skew control. Moreover, the integrated DQPSK receiver offers a smaller footprint suitable for today’s demanding high speed transponder applications.
