Abstract: A spectrophotometer multi-angle viewing device with a housing and holders for a test panel and reference standard. The holders allow rotation of a reference standard 360* in a vertical plane and rotation of a test panel 360* in a vertical plane and + OR 45* from the horizontal in a vertical plane perpendicular to the vertical plane in which the 360* rotation is possible.
