The 10BPF25-400 Bandpass Filter is a 1 inch (25.4 mm) diameter band pass filter with a center wavelength of 400 ± 3.5 nm and a Full Width Half Max of 25 ± 3.5 nm. 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.
