Study Notes
Source Properties for a Selected Range of Wavelength
- A source should have a stable and constant output intensity to ensure reliable measurements.
- A source should generate light in the entire visible range (340-780 nm) for applications in the visible region, as this range covers the entire human visual spectrum.
Importance of Stable Beam Intensity
- Fluctuation of beam intensity can lead to inaccurate measurements and poor data quality.
- Reducing beam intensity fluctuation is crucial to ensure reliable and consistent results.
Reducing Beam Intensity Fluctuation
- Using a double beam setup instead of a single beam can help reduce beam intensity fluctuation.
- A double beam setup splits the beam into two paths, allowing for simultaneous measurement of the sample and a reference, which helps to cancel out any intensity fluctuations.
Radiant Power Requirements
- A source should have enough and suitable radiant power to ensure sufficient signal strength for accurate measurements.
- Adequate radiant power is necessary to overcome losses in the optical system and to detect weak signals.
