AOD650-8 Deflector Performance for 7mm (H) x 30mm (W) beam
Diffraction Efficiency
> 80% across specified scan
Access Time:
5.5µsec
Resolution:
100
Deflector Drive Electronics:
** iMS4-L, RFA200-2 for scanning applications
RFA4060-2K for dual spot modulation
* Optional designs are available for other wavelengths in the 2.5µm - 11.2µm range.
** The iMS4-L /RFA200-2 applies progressive phase shifting across the two RF input channels. This feature compensates for the variation in efficiency across the scan due to Bragg angle errors.
