Description
Shandong Yanggu Constant Crystal Optics, Inc. has been a pioneer in the field of optical glass components manufacturing since 2006. With a commitment to precision and quality, our products are crafted to meet the highest industry standards. Our expertise in optical solutions is evident in every component we produce, ensuring they are at the forefront of technology and innovation.
One of our standout products is the 450nm Long Pass Filter. This filter is meticulously designed and manufactured to provide superior performance and reliability. By utilizing advanced hard film coating techniques, we ensure that our filters offer long service life and exceptional wavelength accuracy. The filter's ion plating further enhances its stability, minimizing temperature drift and maintaining consistent performance under varying conditions.
Our 450nm Long Pass Filter is constructed from high-quality raw materials such as Fused Silica, B270, and Float Glass, among other optical glasses. This choice of materials guarantees high penetration rates and remarkable cut-off depth. The filter is designed to allow wavelengths from 460nm to 1100nm to pass through, with a transmission rate exceeding 95%, while effectively blocking unwanted wavelengths with a cut-off rate of less than 0.05%. These attributes make our filter an essential component for applications requiring precise optical filtration.
At Shandong Yanggu Constant Crystal Optics, Inc., we pride ourselves on our dedication to quality and innovation. Our products, including the 450nm Long Pass Filter, are a testament to our commitment to excellence in the optical industry.
