Trinocular Configuration – Stemi 305 EDU Set

The trinocular version provides enhanced flexibility for documentation and teaching. It supports ZEISS Axiocam microscope cameras and ZEN imaging software. A fixed 50/50 light distribution between the left eyepiece and the camera path makes it ideal for live demonstrations, allowing students or colleagues to follow observations directly on a monitor.

When combined with the Axiocam ERc 5s camera, several connectivity options are available:

• HDMI for direct monitor connection

• USB for use with a Windows PC and the free ZEN lite imaging software

• LAN for integration into a digital network and camera control via the Labscope imaging app on an iPad
