The term ∂Acosθ gives the projected area of the surface element perpendicular to the direction of measurement. Radiant exitance is the density radiant flux leaving a surface at a point (see Figure 1.5b) and is defined by M= ∂Φ ∂2Q = , ∂ A ∂t ∂ A (1.9) where ∂Φ is the radiant flux leaving the surface element.

Silver offers better reflectance in near IR than aluminium and high reflectance across a broad spectrum. Gold is a widely used material and consistently offers very high reflectance (about 99%) in the 0.8–50 µm range. However, gold is soft (it cannot be touched to remove dust) and is most often used in laboratory.
