Product Description

This product achieves non-destructive testing of pearl bead thickness.
Using low power near-infrared light to achieve the non-destructive imaging of pearl, the optical power illuminated to sample is only 4 ~ 6mW, wavelength is 1.3 microns, non-radioactive, completely non-invasive to the testing workers and pearl samples, radiation shield is not needed to and no potentially harmful X-ray radiation to the staffs; compared to traditional prior transmission X-ray imaging, this product uses an innovative non-contact backscatter imaging technology to achieve a single bead detection, and makes semi-finished pearl and finished jewelry measurements become possible; intuitive pearl beads layer images, accurate measurement of the pearl beads thickness, resolution up to 0.*3 mm; instrument miniaturization, installation and use convenient, can be used directly in manufacturing factory, testing organization, distribution units, retail units and other places; fast imaging speed, each sample scan only 0.*5 seconds, sorter optional, suitable for pearl farming and grading, screening of production process.

Applied range:
OCT can be applied in quantitative grading of pearl and qualitative assessment of pearl quality. Conclusions are as follows:
1. Verify the authenticity and varieties of pearls, and distinguish whether pearls is clear;
2. Pearl grating based on nacre thickness  measurement , thickness  range 0.1~4mm  and the error < *0%;
3. According to the pearl internal structure, it can provide supplementary information for pearl cultivation and quality assessment;
4. Without the color and variety restricted;
5. Pearl quality control and identification.
