Performance testing: Spectral response stability
Test condition:
- As the above picture shows (the response curve of deuterium-tungsten lamp), the sharp emission peak is at about 313.18 nm. Therefore, the integration time was set to 10ms at a wavelength of 313.18 nm.
- Preheat for 10 mins, collect once at 2-minute intervals and repeat 100 times.
- Optical fiber: 105μm
Test result:
- Average value of test: 58757.72, fluctuating p-p value: 1093
- RMS: 0.36%
