Brewster window use the characteristics of total reflection property of the material. When the incident Angle (called brewster Angle of the material) is specified, the Polarization component of S in the incident light is partially reflected, while the P component is close to the full transmission.Sunday offers a variety of Brewster Windows based on UV-fused quartz for UV applications The high-precision window is made of BK7 optical glass and UV fused quartz, the fused silica quartz window plate is suitable for high power laser that needs good thermal stability, and the window made of N-BK7 material is cheaper, which is suitable for laser applications that pay more attention to cost.Both fused quartz and N-BK7 laser window plates have precision grades of 1/10 lambda surface flatness and 10-5, 20-10 surface quality to ensure minimal interference to the transmitted beam.Sunday Optics is specialized in the processing of precision optical window,We have four-axis polishing machine, large-size ring polishing machine, two-axis machine to manufacture high precison windows for customers. we can offer 24 inch zygo flatness reports, full CA 600mm windows.Brewster window use the characteristics of total reflection property of the material.

Optical brightening agents (OBAs), also known as fluorescent brightening agents (FBAs), or fluorescent whitening agents (FWAs) are chemical compounds that give a whitening effect to the fabric. They do this by absorbing light in the ultraviolet and violet region and re-emit the light in the blue region. Fluorescent activity is a short-term or rapid emission response, unlike phosphorescence, which is a delayed emission. This blue light reduces the yellow color of the substrate and gives a bright look. At Meghmani, you will find the ideal and quality Optical Whitening Agents. Being one of the leading optical brightening agent manufacturers and suppliers, we ensure delivering only the best products. Product Specification Product Code................
