Manufacturer's part number :


Manufacturer Isomet


Description :

The OAD1550-XY dual off-axis deflector offers high throughput efficiency over a wide scan angle in the NIR range. This deflector has been designed for simplicity and consists of two AO deflector crystals mounted orthogonally in one case. There is no requirement for input or intervening optics between the crystals.
