These galvanometers offer the highest positioning speed and precision accuracy than any compact, lower cost closed loop galvanometer available in today's market. The low inertia, high speed, high accuracy and compact size of these galvos make them suitable in applications ranging from biomedical systems, optical coherence tomography, laser projection, confocal microscopy and analytical instrumentation.
The dual axis servo driver provides optimal repeatability, linearity, stability and cost in a very compact package. An analog command input of up to ±10V DC results in ±20° mechanical degrees of scanner rotation. The error integrator in the servo loop enables microradian level position accuracy. The built-in system conditioning and position and velocity status monitoring make the integration of the driver board easy and accurate in complex scanning system applications. #59-021 and #59-874 include two galvanometers, a dual axis integrating servo driver amplifier, two interconnect cables, an XY galvo mount, and a 3mm aperture XY mirror set.
Note: It is strongly recommended that a heat sink be placed in contact with the servo driver board during operation. The thermal grease improves heat transfer between servo driver board and heat sink (not included). A positive and a negative power supply (not included) are required to operate the driver board. Choose either #66-911 (two required) or #59-026 (one required).
