Finger Lakes Instrumentation no longer manufactures focusers. In the past, we offered three focusers designed to operate with FLI cameras to precisely focus an image: the DF-2, PDF, and Atlas. The DF-2 is a small digital focuser. The PDF is a digital focuser with a large aperture with support for high resolution imaging. The Atlas focuser is designed for a critical focus with heavy loads.
A user's guide for the PDF focuser can be found here.
A data sheet for the Atlas focuser can be found here.
Below is a specifications table pertaining to the DF-2, PDF, and Atlas focusers.
