Hypothesis
Can charge-injection devices effectively detect ultraviolet light for elemental analysis?
Conclusion
The charge-injection device shows satisfactory spectral response for use as a multichannel spectroscopic detector.
Supporting Evidence
- The CID has a sensitivity between that of photodiode arrays and CCDs.
- Studies indicated that the UV response of CIDs has not been accurately measured before this study.
- The maximum visible sensitivity is about seven times that of the UV region.
- The variation in sensitivity from one sensor to the next is about +20% in the UV region.
Takeaway
This study looked at how well a special camera can see different colors of light, especially in the ultraviolet range, which is important for analyzing elements.
Methodology
The spectral response of five CID sensors was measured from 190 to 800 nm using front surface mirrors and quartz optics.
Limitations
Previous studies on UV response were negated due to glass absorption below 350 nm.
