Most of our integrating spheres are available with either a Barium Sulfate or PTFE coating on the internal surface.
Consider specifying PTFE – when the highest possible reflectance and best linearity over the widest possible wavelength range is required, PTFE is recommended.
Consider specifying Barium Sulfate – when a slightly lower reflectance or a bit less linearity versus wavelength is acceptable — and cost is important, Barium Sulfate is recommended. It also has superior durability characteristics when compared to PTFE.
Please note that external coating options may also be available, including gloss or flat finish and a number of color options. Please contact the factory for further information.
