AmScope's MD series digital eyepiece cameras are lightweight and compact, making them perfect companions to any microscope. Another huge benefit is their ability to be used with popular video conferencing apps just like a webcam. This is because they use UVC protocol, making them plug-and-play compatible on most platforms, including Windows, Mac OS, and Linux. Whether remote-streaming a QC line or partcicpating in an online class, the MD series digital eyepiece can connect you to the world. The MD500A is an ultra-compact 5MP USB digital microscope camera, ideally suited for use as an eyepiece camera. By itself, it will fit 23mm ocular or photo ports, but it can be adapted to fit 30mm or 30.5mm ports using the included sleeves. Using the USB interface for both connectivity and power, only a single cable is needed.
