OAD1343-XY-75
Dual Axis AO Deflector
The OAD1343-XY offers high throughput efficiency over a wide scan angle in the NIR wavelength
range. This dual axis deflector consists of two AO crystals mounted orthogonally in one assembly, each with independent angle adjustment. There is no requirement for input or intervening optics between the crystals.
