Praseodymium-Neodymium Glass
- Product Item : AT-61060
- Category： Optical Cover Glass Materials
- Product description：
Praseodymium-Neodymium (Pr-Nd) glass is a specialized optical glass containing a combination of rare earth elements praseodymium (Pr) and neodymium (Nd), which are incorporated into a glass matrix in specific proportions. This glass possesses unique optical modulation capabilities. Its appearance is typically silvery-gray or slightly yellowish. Although the color characteristics do not directly determine its performance, they can optimize the imaging quality of optical devices by adjusting light transmittance and refractive index. For example, it is used in precision instruments such as camera lenses and telescopes.
