Angular Spectrometer LASM-A10 is a tabletop unit, offers angle measurement accuracy of 1 inch and diopter compensation range of ≥ ± 5 diopters. Incorporated with two verniers at the opposite edges, to remove errors induced by the off center errors of the divided circle and thrusting bearing under the divided circle for smooth rotation. Equipped with magnifier with handle, optical parallel plate and planar holographic grating. Built in with adjustable dioptre, moveable telescopes eyepiece and adjustable stage.
Angular Spectrometer is widely used for angular measurements based on polarization, diffraction, refraction and interference. It is commonly used in color measurements, concentration determination of chemical components and electromagnetic radiation analysis.
