Transmitting through a Window

1. Determine the number of surfaces the beam transits or is reflected

from, the reflectivity of each surface, and

condensation/precipitation collection areas.

2. Use the data below to determine whether the light beam

attenuation is acceptable.

4% attenuation for each surface of light

reflection.

15% attenuation for a double pane window.

Attenuation due to tint in windowpane must be

taken into consideration in choosing the right

TereScope model. (The % attenuation depends

on the tint and must be measured.)

3. Ensure that the angle of incidence

of the beam striking the

windowpane is between 1º and 45º.

Note

On high buildings, for indoor window installation, the user should consider

that occasionally the window-cleaning elevator might block the link beam.
