Model No:P-837B
Experiments:
1. To determine the radius of curvature of the given concave lens by forming Newton's rings with the combination of convex and concave lense
| Parameter | Specification |
|---|---|
| Newton Ring Microscope | Built in Newton ring assembly, with plane adjustable glass and condenser lens ReadingThe longitudinal movement of the microscope for the purpose of the Rings is done by rotating the drum. The 26mm moment can be read by scale and on the divided drum to 0.001 cm. Ring Newton's Ring consists of optical flat glass and one Plano-convex lens (25mm radius) arranged inside a metal case resting over the stage of the instrument where Rings are formed which can be adjusted with the help of three screws provided for the purpose of alignment.Reflector Plate is fitted on the side of the attachment whose angle is to be set at 45? or such that light should fall inside the Newton's lens. The Condenser lens: is provided in front of the reflector. |
