Technical Specifications
| Specification | Value |
|---|---|
| Eyepiece | 10x Ramsden, cross-hair |

How It Is Used
The base is levelled using the screws and spirit level, and the microscope is focused on one edge of the object with the cross-hair aligned. The scale is read, the microscope moved to the opposite edge and read again; the difference gives the dimension. It is used for capillary tube bores, thin film thickness and apparent depth for refractive index.
Frequently Asked Questions
What is measured with the Travelling Microscope?
