We're happy to answer all your questions about this product.

  1. A We did some research about the question below and found some good news and bad news. The bad news is that the MS Hololens doesn’t appear to support external peripherals through its USB port. This is mainly used to connect to an external power source or to connect with an external PC for data transfer. Unfortunately using a USB microscope here is (probably) not an option. The good news is that MS Hololens claims to support external WiFi inputs. If this is the case, we may have a solution but this will require integration work on the customer side. Firefly is in the process of launching a WiFi-based High-Definition Digital Dermatoscope (Model DE370) which can be used as a microscope. This device can send an HD video stream to the Hololens over WiFi but we don’t have an App that can run on the Hololens. We can instead provide an SDK which can be used to build an app. Would you like to entertain this endeavor? Please advise if I can be of further assistance. Once again, thank you for contacting New York Microscope Company.
