Photoluminescence Imaging with Solis B0465 sCMOS Camera
Industry pain points and demands
In pressure-sensitive paint (PSP) photoluminescence tests, the main difficulty is capturing the very weak signals created by oxygen quenching. Researchers also need accurate data to measure fast pressure changes.
The coating’s light intensity changes in a nonlinear way with oxygen partial pressure (oxygen increases → light intensity decreases). When oxygen levels are low, the weak signal is easily covered by noise, making pressure mapping hard to measure.
SinceVision Solution: Solis B0465 sCMOS Camera
01Ultra-high sensitivity and low noise: A back-illuminated sensor with QE ≥ 95% and TE cooling lowers dark current. It captures weak fluorescence signals under low-oxygen conditions and keeps the “light intensity–oxygen partial pressure” calibration curve accurate.
02Long exposure capability: Supports long exposures lasting several minutes. Deep cooling reduces dark-current noise and prevents dark current from covering weak PSP fluorescence, especially in low-oxygen or high-pressure settings with very low light.
03Optimized for quantitative analysis: Light-response non-uniformity is under 0.5%. A 12-bit ADC provides stable light-intensity data. ROI mode allows simultaneous imaging of multiple calibration points, improving test efficiency.
