What We Measure, Part 2: Transmittance

Previously, we reviewed the first of the basic units we measure: reflectance.¬†We presented a simplified but rigorous definition of the way we quantify the flux reflected from a surface. In a similar way, this post addresses transmittance, which describes the … Read More

What We Measure, Part 1: Reflectance

The material properties we measure are reflectance and transmittance. The specific definitions can be complex and confusing, but we will present an explanation at the level of the non-expert in the spectroscopy and color measurement communities. Reflectance is the more … Read More
