PRODUCT APPLICATION
The SD-6 Large-Range Diopter Tube is primarily used for testing and calibrating the diopter difference of optical instrument eyepieces. Its main functions include:
- Testing the diopter range, diopter zero position, and diopter accuracy of optical instrument eyepieces.
- Measuring the diopter and diopter zero position deviation values of optical instrument eyepieces.
- Serving as a fore-optic when testing imaging quality and resolution of optical instruments.
