Easy Mounting on Trinocular Microscopes with the Included C-Mount Adapter

C-mount adapter

For users who want to mount the camera on a trinocular microscope, a C-mount adapter is included as standard.

If your trinocular port has a standard C-mount thread and no built-in correction lens (i.e., 1× magnification), simply remove the ring adapter from the SCORP-ON Direct USB and attach it directly using the included C-mount adapter.

Please note:

  • Some microscopes have built-in correction lenses in their C-mount ports, which may prevent proper attachment. Be sure to check compatibility in advance.
  • Although this product is primarily designed for use as a microscope camera, it can also be used as a standalone USB camera. By replacing the ring adapter with the C-mount adapter and attaching a C-mount CCTV lens, you can easily repurpose it for non-microscope applications as well ― a useful option for those looking for more flexible usage.
