UV energy meter stability comparison test

2018-04-02 12:48:47

UV LED light source is currently widely used in UV curing, UV exposure, UV flat printing, optical communication and other industries, and UV energy meter LS128, is mainly used for the power and energy value detection of UV LED light source. Test 365nm, 375nm, 385nm, 395nm, 405nm and other bands of UV LED light sources can be.

Tools/Materials
1

UV LED light source one

2

UV energy meter LS128 one

3

One scale

Methods/Steps
1

First, in order to ensure that the position of each test remains consistent, a ruler is fixed.

2

Turn on the UV energy meter, press the POWER key to confirm the start of a new test, then turn on the ultraviolet lamp, and point the power probe of the instrument at the light source.

3

The energy value of the first test of the UV energy meter is 3396mJ/cm², and the power value is 671mW/cm².

4

Repeat the above test steps, and then test the second time in sequence with an energy value of 3399mJ/cm² and a power value of 672mW/cm², and the third time with an energy value of 3394mJ/cm² and a power value of 671mW/cm².

5

UV energy meter repeated tests, the data is very stable.

Matters needing attention
1

The test position of the UV energy meter should be consistent

2

The UV LED light source should also remain in the same position

Recommendation
