Newport MKS Bandpass Filter, 50.8x50.8 mm, 440±2 nm Center, 10±2 nm FWHM 20BPF10-440

The 20BPF10-440 Bandpass Filter is a 2 x 2 inch (50.8 x 50.8 mm) square bandpass filter with a center wavelength of 440 ± 2 nm and a Full Width Half Max of 10 ± 2 nm. See Curve 11, for transmission graph. Our Bandpass Filters pass a narrow spectral band of UV, visible, or NIR radiation and reject out-of-band wavelengths from the X-ray to the far IR. Applications include spectral radiometry, medical diagnostics, chemical analysis, colorimetry, astronomy, and wherever spectral isolation is required.
