OAD1344-XY-75
Dual Axis AO Deflector
The OAD1344-XY offers high throughput efficiency over a wide scan angle in the NIR wavelength
range. This dual axis deflector consists of two AO deflector crystals mounted orthogonally in one
assembly, each with independent angle adjustment. There is no requirement for input or intervening optics between the crystals.
