Optical Scanners and Deflectors
Acousto-Optic Deflectors
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

KTN Deflector Modules
Crystal-based Deflector; Scanning Angle ≤150 mrad; Scanning Speed ≤100 kHz; 488 to 3,500 nm NTT Advanced Technology Corporation’s KTN deflector module will realize new technological ideas, with ultra-high-speed scanning and arbitrary scanning. High-speed operation, which has not been supported by conventional technology, becomes possible because the light is controlled by electron transfer and an external electrical field without any mechanical moving parts. For example, when it is applied to a laser radar, higher speed object recognition will be possible compared with conventional technology.As the device features a simple structure of electrodes formed on a crystal and the chip size is very small, the optical polarization module can be mounted in a small-size housing of only 2 x 3 x 6cm. Flexible optical scanner operation is realized by devising an appropriate voltage supply method, because the voltage supply and direction of travel of the light beam correspond to each other, and the operation speed is very high. For example, the light scan angle can be made to move instantly among multiple points by inputting a digital signal, while continuous scan operation is realized by inputting an analog signal. In consequence, the device will be optimum for applications such as a laser radar or a laser scan display, by making use of its flexible operability from continuous operation to arbitrary scanning.Key Features:Wide Deflection Angle up to 150 mradHigh Response Frequency up to 100 kHzBroad Wavelength Range 488 to 3,500 nmPolarization Maintaining Single Mode Optical FilterApplications: Laser Processing; Laser Scanning Microscopes; 3D-Measurement; Optical Communication; Displays; Optical Storage Media; Imaging; Sensing; Printers; Copiers; Forward Monitoring Sensors in Automobiles; OCT Swept Laser Source and Imaging; Flow Cytometry; High-speed Spectrometers; Optical Switches; Pulse Pickers
