Demonstration Spherometer Subcategory_Weights and Masses Paired safety-socket outputs deliver two

Paired safety-socket outputs deliver two selectable ranges 0-70V and 0-125V DC at 300mA

fastened by two wide-pad stainless steel thumb screws under heavy torsional load

and steel cubes machined to the same 1

the 90-45-45-degree faces redirecting wider beams for total internal reflection and image-inversion work

the wider bore accepting full-size bar magnets while AC current drives the alternating field that rotates domains for demagnetization
