Kyle took high quality images of the three sapphire prisms using the microscope @Downs. He analyzed the images to see the radius of the groove.
They all look sufficiently sharp for a 46um steel wire. Thumbs up.
I am curious to see how the wire Q is with grooved sapphires, ungrooved sapphires, grooved ruby, grooved aluminum stand off, and so on. |
