Gem-A Diffraction Spectroscope Arbe USA Vulcanizer for Rubber Moulds Overall size: 205 x 55For pure transparent (non opaque) stones. Each type of stone has its own spectrum colour diagnostic. Simular to the prism spectroscope but works by diffracting white light to give non prismatic perspective. Light enters through a narrow slit and is then diffracted by a thin film of diffraction grating material. This produces a linear spectrum image with a generally larger view of the red part than a prism spectroscope. The spectroscope is a small and
