Heraeus is a kind of fused silica material, many factors should be considered before selecting optical uniformity, reflection and absorption of bubbles or impurity content, refractive index and dispersion, residual stress, fluorescence, tolerance to light-induced defects or radiation, cost. Before selecting, we should first consider the wavelength range of optical devices: 180-380nm ultraviolet, 780-3600nm infrared, 380- 780nmvisible light applications and 200-3600nm broadband applications
