About This Product
Where the curved lens face meets the flat plate, a thin air film forms and produces the circular interference fringes known as Newton's rings. Tightening the compression screws evenly sets the contact between the two elements. The Newton's Rings Apparatus can be dispatched from India to Madagascar, Malawi, North Macedonia, Tanzania and Côte d'Ivoire.
