Spherometer measures
WebNext, verify the relevant diameter on your Delrin ring. I am going to measure a convex surface, so I measured the ID of the ring and got 5.00mm exactly. It's important to record if your diameter is a little off, like 4.88mm, because that will affect your math later. Place the end of the spherometer anywhere on the lens element you want to measure. WebThe spherometer depends on the correct working of all the pressure sensors - there is more to go wrong. Interferometric methods are self correcting and self calibrating. Lastly, the 3cm error by itself sounds nasty, but needs to be thought of in the context of other lens parameters: it may not be that bad.
