Brunson 190 Series Optical Micrometer UNIT OF MEASURE:Inches .001" they turned to one ofThe 190 optical micrometer translates the line of sight laterally with an accuracy of 0. 0005 using an optical flat. The cast aluminum housing has a 1. 655 opening to fit the telescope barrel of all Brunson optical tooling transits and levels. Adapters are available which allow this micrometer to be used with a variety of theodolites as well. Any of four machined slots in the housing (located at the 12, 3, 6, and 9 oclock positions) fit over a
