Demonstration Spherometer Subcategory_Weights and Masses the 90-45-45-degree faces redirecting wider

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

supplying replacements when the originals lose loft or split during repeated charging cycles

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

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