reflectancespektroskopi
Reflectance spectroscopy is an optical technique used to measure how much light a sample reflects across a range of wavelengths. Unlike transmission spectroscopy, which measures the light that passes through a sample, reflectance spectroscopy analyzes the light that bounces off its surface. This method is particularly useful for opaque or thick samples where transmission is not feasible.
The basic principle involves directing a beam of light onto the sample's surface and then collecting the
Reflectance spectroscopy can be performed in various configurations, including specular reflectance, diffuse reflectance, and bidirectional reflectance.
