1 Scope

GB/T 32561 this part of the provisions of the infrared optical sulfur glass uniformity of the test principle and equipment and equipment, test conditions, test

Samples, test procedures, data processing, measurement uncertainty and test reports.

This part is suitable for infrared optical sulfur glass uniformity test, can also be used for other infrared optical glass, infrared crystal, infrared ceramic

And other infrared material uniformity detection.

2 terms and definitions

The following terms and definitions apply to this document.

2.1 Homogeneity

The same piece of infrared optical sulfur glass, in the direction perpendicular to the specified optical path unit cross-sectional area, the unit optical path thickness of the refractive index distribution is not

Consistency, usually characterized by refractive index PV and standard deviation.

[ISO 10110-4, definition 2.1]

2.2 Refractive index PV value

PVdeltan

The difference between the maximum value and the minimum value of the refractive index distribution of the interference test.

3 test principle

The wavefront error was measured by the interference method to obtain the distribution of the refractive index difference of the material, and the refractive index PV (PVdeltan) of the uniformity of the material was calculated.

Values and standard deviations. Four-step interferometry test principle shown in Figure 1.
