  1. 1. The difference between LS163 (940nm) and LS163A (1400nm) window film transmission meters

    The main difference between LS163 and LS163A is that the peak wavelength of the built-in infrared light source is different, LS163: 940nm, LS163A: 1400nm. These two wavelengths are more representative, most of the absorption film has a better rejection effect at 940nm. The metallic film (insulation by reflecting heat) has a better rejection effect at 1400nm. Please choose the appropriate model according to your own film.

  2. 2. What are the advantages of LS163/LS163A over previous window film transmission meters?

    The screen can rotate in four directions; 

    Three display interfaces can be switched: 

    1) UV rejection, IR rejection, VL transmittance

    2) UV transmission, IR transmission, VL transmittance

    3) VL transmittance
