Bandpass Filter, 50.8x50.8 mm, 340±2 nm Center, 12±2 nm FWHM

The 20BPF10-340 Bandpass Filter is a 2 x 2 inch (50.8 x 50.8 mm) square bandpass filter with a center wavelength of 340 ± 2 nm and a Full Width Half Max of 12 ± 2 nm. See Curve 6, 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.
