Schott is now the first manufacturer to offer special optical glasses with a tolerance level of 0.5. The maximum deviation from the nominal values listed in the datasheet is only ± 0.0001 with the refractive index nd and ± 0.1% with the Abbe number vd with this new level of quality. This means Schott has the narrowest optical tolerances available in the market. Glasses of the tolerance level 0.5 are particularly well-suited for use in high precision lenses. To achieve the best possible resolution, several lenses must be precisely in tune with each other. The narrow optical position of the glasses helps to improve the quality of the lenses used in inspection systems in industry or microscopy. For more information, please visit: www.schott.com
