PureFocus™850 Laser Autofocus System

Laser autofocus system providing real time focus recapture for life science and industrial microscopy. Compatible with both upright & inverted infinity corrected optical systems. Filter Wheels, Turrets & Shutters Evident Microscope Automation Nikon Microscope Automation Leica Microscope Automation Zeiss Microscope Automation Automated Custom Imaging Systems PureFocus850 combines advanced optics and intelligent microprocessing to provide a real-time focus system for infinity-corrected optical systems. It offers sample detection, dynamic power adjustment, and long focus recapture range. A motorized offset lens allows adjustment of the imaging depth into the sample, continuously holding the precise distance between the imaging focal point and a reference interface of choice or enabling different discrete image planes to be acquired using the same interface. Mounted in the infinity space, it is compatible with most brands of commercial microscopes as well as Prior's OpenStand imaging platform, Queensgate piezo devices, and can be adapted for third-party focus actuators. See product compatibility tab for details. Designed for versatility, PureFocus850 is suitable for applications where it can detect a reflective surface. As well as metallurgical, geological, and semiconductor samples, it can be used for life science applications using slides, glass bottom dishes, and flow chambers. The laser's 850 nm operating wavelength does not interfere with common wavelengths used for illumination and imaging. Users can choose to operate the PureFocus850 as a standalone device or integrate it with control software as part of a comprehensive automated imaging system. Rapid automated focus recovery for numerous applications Integrated stepper motor driver and interface to Piezo and other actuators via 0-10 V analog output Easily adapted to any infinity optical system, both upright and inverted Stores and recalls multiple objective-specific parameters for multi-objective use Customizable optics for specific imaging applications
