Golden Yellow Glass (Cut-off Type)

Product Description: 

The transmission wavelength limit (λtj) is defined as a wavelength which corresponds to 50% of the maximum transmissivity on the spectral transmission curve with a glass thickness of 2mm.

The slope of absorption curve is represented as the differece betweeen optical density D(λtj-20) and D(λtj) with a glass thickness of 2mm.
