Use only mild soap and water to clean prisms! Alcohol will degrade the quality of the product over time.
Our exclusive manufacturing process greatly reduces optical strain, producing prism bars that virtually eliminate clinical birefringent effects. The vertical prism bar is calibrated for use in the Prentice position. The horizontal bar is calibrated for use in the Frontal Plane position.
