The DAF-1000 has been specifically designed to provide a high resolution and highly repeatable, means of controlling the focus / Z position of the microscope stage. Precise control of the microscope's focus is obtained through the use of a step DC servomotor employing high resolution encoders for positioning feedback. By using image control of the focus position, there is no chance that the focus point can be lost as can occur with stepper motors. With the advanced PC software control, the auto focus system outputs images through PC monitor or projector, therefore it is very easy and availability and can be used in all kinds of microscope observation system with z-axis control.
A easy-fits design, when installed, they become an integral part of the microscope. When disengaged, the microscope can be focused manually without any drag or twisting cables. Installation of the Z-axis drive requires no modification to the microscope.depending on the particular microscope. All of the necessary hardware components and detailed instructions are provided with every unit.
(The inside fitting diameter of the sleeve is designed to be slightly larger than the coarse knob, provided the lock screws have not been tightened and are compressing the sleeve.The controller is factory configured to drive the focus motor in the correct direction when mounted to the left hand side of an upright microscope. If the right hand coarse control knob is preferred by the user or the focus drive is to be mounted on an inverted microscope, the motor direction need not to be changed. It will still get the correct focus position.)
The DAF-1000 control unit provides for USB2.0 communication with a host computer.
DAF-1000 Microscope auto focus system provides several kinds of observation methods, monocular, binocular, dual-viewing observation and trinocular image acquisition by digital CCD camera / eyepiece. It is easy to use z-axis control both in observation and auto focus processes. The auto focus system consists of digital CCD camera / eyepiece, z-axis controller and auto focus circuit controller, and it can be widely used in rapid detection application in biology and semiconductor industry.
Features
*Step DC servomotor control of Z-axis for precise positioning and highly repeatable focusing
*Compact ergonomic tabletop control unit
*Utilizes Z-axis DC servomotor drives
*Z-axis clutch for easy switching between manual and motor-driven focus control
*Controller processor control with USB serial communications
*USB2.0 High-Speed serial computer interface
With the multi-layer image grab function, intelligent software will slice your specimen at along the varying z-intervals to capture different completely focused images and then you can fuse them into a single image.
