KTN Deflector Modules

Wavelength 266-1100 nm; Type IR, Visible, UV, Mid-IR; Scan Angle 4,9-60 mrad; Active Aperture 1.0-60 mm; Operating Frequency 9.4 µm-432 MHz; Optical Material Germanium, Sapphire, Fused Silica, Crystalline Quartz, Tellurium Dioxide G&H acousto-optic deflectors (AODF) provide precise spatial control of an optical beam, whether performing 1D or 2D scanning or executing beam deflection through a fixed angle. The acousto-optic deflectors offer highly uniform diffraction efficiency across the full scan angle, with consistent power throughput for scanning applications like material processing and digital imaging. Gooch & Housego offers a wide range of standard deflectors and RF drivers for wavelengths from 266-1500 nm. Key Features: Visible and NIR wavelength products based on tellurium dioxide crystals, grown in-house UV wavelength products based on fused silica and crystal quartz Broad bandwidth products based on a longitudinal mode approach using a phased array of piezoelectric elements High efficiency products based on slow shear deflection using parallel tangents off-axis interactions Selecting the right RF driver is important to achieve the desired scanning speed and accuracy. Deflectors used in scanning or writing applications require a variable frequency source which is both stable and highly linear. 2D UV beam scanning may be achieved by cascading two UV deflectors in series. Gooch & Housego’s flexible functionality AODF Dual Driver with phase synchronized outputs offers the optimum in RF driver control for 2D scanning.Applications: Digital Imaging; Heterodyne Interferometry; Laser Cooling; Laser Marking; Laser Tweezers; Material Processing; Micromachining; Microscopy; On-Line Process Control; Optical Inspection; Photolithography; Printing Series Wavelength Type Scan Angle Active Aperture Operating Frequency Optical Material Downloads AODF 4070 N/A Mid-IR 60 mrad 9 mm 9.4 µm Germanium Datasheet Driver Driver AODF 2690-UV 266 - 355 nm N/A up to 4.9 mrad up to 7 mm 100 - 432 MHz Sapphire Datasheet Driver Driver AODF 4200-UV 266 nm UV 5.5 mrad 1.0 x 60.0 mm 135 - 265 MHz Fused Silica Datasheet Driver Driver AODF 4170 355 nm UV 4.9 mrad 7 mm 130 - 210 MHz Crystalline Quartz Datasheet Driver Driver AODF 4100-UV 364 nm UV 29.5 mrad 4.0 x 14.0 mm 75 - 125 MHz Tellurium Dioxide Datasheet Driver Driver AODF 4200-VI 405 - 488 nm Visible 58 mrad 4.8 mm 150 - 250 MHz Tellurium Dioxide Datasheet Driver Driver AODF 4090-7 440 - 530 nm Visible 44 mrad 8.5 mm 60 - 115 MHz Tellurium Dioxide Datasheet Driver Driver AODF 4100-VI 488 nm Visible 39.5 mrad 4.0 - 14 mm 75 - 125 MHz Tellurium Dioxide Datasheet Driver Driver AODF 4055-4 780 - 980 nm IR 44.3 mrad 3.5 x 14 mm 35 - 70 MHz Tellurium Dioxide Datasheet Driver Driver AODF 4210-IR 830 nm IR 27.6 mrad 2.0 - 6.0 mm 140 - 280 MHz Tellurium Dioxide Datasheet Driver Driver AODF 4090-6 1064 nm IR 56 mrad 2 mm 72.5 - 107.5 MHz Tellurium Dioxide Datasheet Driver   AODF 4075-IR 1065 - 1100 nm IR 8.1 mrad 2.5 mm 59 - 91 MHz Tellurium Dioxide Datasheet Driver Driver
