SLP-2000(SURFACE STRESS METER)
This machine is a glass stress meter measuring Compression Stress(CS) and Depth of Layer(DoL) of glass based on Scattered Light Photoelastic method. Stress distribution of chemically tempered glass which is strengthened by ion-exchanging from Lithium ion(Li+) to Sodium ion(Na+) is evaluated by this method. A glass plate that is strengthened by mixed liquid KNO3 and NaNO3, K+ layer should be measured by FSM-6000LE,on the other hand Na+ layer should be measured by SLP-product. Data acquired by FSM-6000LE and SLP-1000/2000 can be combined each other with the special software.

* The data combination is required an optional FsmV dongle.
* In case of using 405nm LD continuously for a long time, the optical parts in the machine will be damaged so the parts replacement is necessary in a short cycle.
