Homogeneity optics
Web7 jun. 2024 · Homogeneity: Optical homogeneity better than 10 ppm, typical 5-6 ppm in clear aperture of ingot. TWE of 1/10 th wave is easily achievable at thicknesses under 1 inch . Additionally, Heraeus has a full line of optical glass for a variety of applications. WebOptical Homogeneity (nΔ) is guaranteed by use of our He-Ne laser interferometers. The nΔ specification is indicated for three diameter ranges ( ∅ Ø 160 mm or less, ∅ Ø 210 mm or less, ∅ Ø 260 mm or less) due to the nΔ variances caused by glass type, size, and shape.
