Accessory set for the interferometer

The Accessory Set for the Interferometer is a great product to help you perform even more experiments with an interferometer. It is suitable for both the Interferometer and Mach-Zehnder Interferometer. The set comprises a vacuum cell for determining the refractive index of air and a glass plate on a rotatable holder for examining the surface quality of optical components (Twyman-Green interferometer).

uses of the interferometer accessory set

The accessory set can be combined with an interferometer for a range of experiment topics, including:

• Determination of the refractive index of glass
• Determination of the refractive index of air
• Twyman-Green test for optical components (qualitative)
