*Back Focus Consumed

For the convenience of calculation, all the data displayed are the increase in the back focal length taken up by using the adapter, which is not necessarily equal to the thickness of the component itself. All the adapter data provided by QHYCCD are based on the focal length increment.

The calculation of Filter Wheel’s back focus consumed includes two parts: the thickness of the filter wheel body (like the 15.5mm of CFW3S-US), and the back focus consumed (like 4mm of CFW3S-US).
