450nm Hard Film Longpass Optical Filter

One of our standout products is the 450nm Long Pass Filter. This longpass 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 Longpass 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 longpass filter an essential component for applications requiring precise optical filtration.
