PFA-DT

WDI’s next-generation Precision Focus Automation “PFA” technology features the world’s most powerful microscopy autofocus sensors. Driven by demand from the Biomedical industry for fast and accurate autofocus solutions, WDI has developed and refined its technology to create PFA-DT. The new sensor provides many advancements in speed, accuracy, processing, and communication, all at a very affordable price.

 

Features

• Continuous focus on multi-layer, varied substrate surfaces with high NA, including immersion, objectives.
• Offset Adjuster (OA) lens versions available to compensate for variances between the sensor focal plane and the camera imaging plane.
• Higher update rate and faster measurements result in improved high-speed tracking performance, Up to 8 KHz sample rate and improved processing power, coupled with Gigabit Ethernet communication create the fastest autofocus solution available today.
• Featuring a configurable output supporting both analog output and digital step and direction, making it a universal solution that can interface with Piezo actuators, Dover Motion’s DOF-5, WDI’s new integrated Z stages, and other third-party Z-axis stages.
• Real-time diagnostic and performance reporting with insightful analytics and statistical metrics.
• Available laser wavelengths include 660nm, 785nm, 850nm.

Applications

• Ideal for live cell, high content screening, genotyping and DNA sequencing applications
