Hovercam Microscope Adaptor 28Mm Dia.

Microscope Adaptor 28mm Dia for the HoverCam Visualiser range. These adaptors are designed for Microscopes with a 28mm eyepiece. They clip onto the HoverCam Spark, Ultra 8 or Solo 8 Plus, and slot over the eyepiece of the microscope. There are two adaptors included, and they are of different lengths. This is because some microscope eyepieces require the camera lens to be closer to the eyepiece than others do. As humans, when we look through the eyepiece we naturally move our eye closer or further away from the eyepiece until we get a clear, circular image of the slide. With the Visualiser, the two adaptors can be swapped to find the ideal one for the adaptor that you're using. What you're aiming for is a circular image on the display, with a sharp edge.Best Way to Focus the Microscope:1. Start with the microscope out of focus on the slide. Attach the adaptor, so that you can see a clear circular image (i.e. no blurring around the edge).2. Use the Focus Lock feature on HoverCam to lock the focus. This stops the Visualiser constantly autofocussingduring use. Also, if you are using an eyepiece graticule, it will focus the Visualiser onto this.3. Finally, use the Microscope focussing dials to bring the slide clearly into focus.
