glass

ofiber.refraction.glass(number)

Return an array of Sellmeier coefficients for glass.

The glasses all have a number. This number is used to look up the Sellmeier coefficients for glass. The number can be looked up with ofiber.glass_name.

Use like this::

num = ofiber.glass_index(“SiO2”) glass = ofiber.refraction.glass(num) # SiO2 n = ofiber.refraction.n(glass,632.8e-9)

Parameters:

number – glass number

Returns:

array of Sellmeier coefficients
