The PSAW vertical reading microscope consists of a microscope with rack focussing adjustable vertical column. The stereotyped design of the vertical column moving through 15 cm by rack & pinion is now replaced by a superior quality vertical pillar carrying the scale with the entire 15 cm vertical lift by smooth rack & pinion, moving inside a heavy vertical column carrying the brass vernier. Vernier spring is loaded for precise apposition to the scale. A guide slot & key ensure up & down movement in the same plane.
The stainless steel scale & vernier is machine divided to accuracy within 0.01% or better. The horizontal microscope tube is mounted on the vertical column, and is adjustable by smooth rack & pinion, through twin knobs on both sides. The microscope moves on the machined inter ground guides.
