What is a Detector Efficiency Curve?
A detector efficiency curve shows how efficient a detector is at converting photons into digital signal. Below is a typical efficiency curve for StellarNet detectors: Absolute efficiency (%) is plotted versus wavelength. At ~475 nm, the efficiency is 100%. This means...What is a Detector?
A detector is a device used to record the signal in a spectroscopy experiment (or in general). For example, camera film is a type of detector. The coating on the film reacts to the light directed to it by the camera optics and records an image. Digital cameras also...What is broadband?
Broadband is an adjective used to describe light sources with a large wavelength range. While there is no clear cut numerical definition, hundreds of nanometers is usually called broadband. Many lamp sources, such as tungsten halogen lamps, are broadband. Lasers can...What is a spectrometer’s System Sensitivity Curve?
The system sensitivity curve shows the total efficiency of the spectrometers. The total efficiency is a combination of the grating, detector, and optics. Below is a system sensitivity curve for a VIS BLUE-Wave spectrometer model: It was generated using a halogen lamp,...What is a spectrometer’s grating efficiency curve?
A grating efficiency curve shows how efficient a grating is at diffracting light at each wavelength. Below is a grating efficiency curve for the VIS BLUE-Wave spectrometer model: Absolute efficiency (%) is plotted versus wavelength. At 500 nm, the efficiency is ~75%....
