2Input and output polarisations are in the same direction. Orientation is indicated on the input face of the DTD.
36 mm Active Aperture Height is also available.
4For Optical Tweezers applications: Model DVE-120 synthesized RF frequency PCI computer card and DPA series poweramplifier.
5For Linear Scanning applications: DE series Voltage Controlled Oscillator drivers.6Since both deflection angles can not originate at the same point, the origins are as close together as physically possible.
