Dioptrometer Series

The Dioptrometer is designed for measurement and calibration of eyepiece diopter parameters in optical instruments. It can be used for diopter range testing, zero-position verification, deviation assessment, and as a pre-lens for imaging quality and resolution evaluation.

This series includes Model 02 and Model 025 Dioptrometers for laboratory, production alignment, and optical system testing applications.

Functions include:
1、Measurement of eyepiece diopter range, zero position and diopter accuracy
2、Testing of eyepiece diopter and zero-position deviation
3、Pre-lens application for optical imaging quality evaluation

4、Auxiliary use in resolution testing and optical calibration
