Bk7 vs fused silica
WebApr 6, 2024 · See the Comparison tab for a side-by-side comparison of the wavelength-dependent transmission of N-BK7 and UV fused silica. These diffusers feature 120, 220, 600, or 1500 grit polishes. Our polishing process results in surfaces with significantly greater uniformity than those of sandblasted diffusers. WebFor example, natural quartz glass in the UVC range has a much lower light transmission than optical quartz glass (fused silica). If high transmission of more than 80 % at 185 nanometers is required , fused quartz cannot achieve this . Besides, the optical homogeneity of natural fused quartz is generally much worse than that of optical grade ...

WebDuring the diamond coating process, the temperature change rate is set to between 50 and 1000 degrees Celsius. The process involves the coating of a thin layer of diamond on a silicon wafer substrate. It is a relatively stable coating, as the diamond adheres very well to the silicon wafer. WebWhen compared to N-BK7, UV fused silica is transparent over a wider range of wavelengths (185 nm - 2.1 µm) and also offers a lower index of refraction as well as better homogeneity. It is scratch resistant and has a …
