In this case, the incidence angle is called “critical angle”.

This angle of incidence is called the critical angle.

incidence angle modifier’ (IAM) means the ratio of the useful heat output of the solar collector at a given incidence angle and its useful heat output at an incidence angle of 0 degrees;

θ = angle of incidence with respect to normal [rad]

incidence angle modifier’ (IAM) means the ratio of the useful heat output of a solar collector at a given incidence angle and its useful heat output at an incidence angle of 0 degrees;

Angle of Incidence - The angle at which the light rays strike the surface.

Angle of incidence – Angle between incident ray and normal

Light: Wavelength (colour), direct/diffuse illumination, non-polarised/polarised, angle of incidence

Orient mirrored side toward source at 0° angle of incidence.

This easy-to-use tool will allow you to dynamically convert from incidence angle to viewing angle, and vice-versa.

If the angle of incidence is greater than the critical angle, Total Internal Reflection will occur.

The most satisfactory results are obtained with an angle close to 60°.

Angle of Incidence - The angle between an incident ray and the normal to a reflecting or refracting surface.
