Microscope digital camera adapter for the Canon PowerShot A540. The camera adapter fits either a 23mm or 30mm inside diameter eyetube. The microscope adapter threads directly onto the camera and then replaces the existing eyepiece by dropping directly into the eyetube or trinocular port. The adapter has 10x custom lenses built into it and the camera will see the equivalent as if looking through a 10x eyepiece on the microscope.
