Flatness of photovoltaic glass panel

Optical Flats |

The flatness of an optical flat is measured in fractions of a reference wavelength, 632.8nm. A λ/20 flat will have a maximum peak to valley deviation of 632.8/20 or 31.64nm. We offer several levels of flatness for our single surface flats : λ/4, λ/10, and λ/20.
