Built with interference thin-film technology, they deliver high in-band transmission and strict spectral selectivity for spectroscopy, laser systems, and imaging. Narrow bandpass filters offer passbands typically in the 1–10 nm range, making them ideal where precise center-wavelength (CWL) and bandwidth (FWHM) control is required — laser line selection, fluorescence excitation, and laser spectroscopy.\u003c\/p\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eFemtosecond \/ picosecond laser systems\u003c\/li\u003e\n  \u003cli\u003eFluorescence microscopy (excitation selection)\u003c\/li\u003e\n  \u003cli\u003eLaser spectroscopy \u0026amp; spectral analysis\u003c\/li\u003e\n  \u003cli\u003eQuantum optics \u0026amp; precision imaging\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eConstruction \u0026amp; Performance\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSubstrate:\u003c\/strong\u003e UVFS Corning 7980 0F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating:\u003c\/strong\u003e IAD Hard Coating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 25.4 × 12.7 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 6.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStart wavelength:\u003c\/strong\u003e 1025 nm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOD:\u003c\/strong\u003e \u0026gt;4.0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTransmission:\u003c\/strong\u003e 70%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePassband:\u003c\/strong\u003e 1020–1030 nm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlocking range:\u003c\/strong\u003e 200–1020 \u0026amp; 1030–1200 nm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating spec:\u003c\/strong\u003e HR@200-1020\u0026amp;1030-1200 nm, T=70%@1025 nm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface flatness:\u003c\/strong\u003e λ\/10 @ 633 nm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface quality:\u003c\/strong\u003e 20-10 S-D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter tolerance:\u003c\/strong\u003e +0.0\/-0.1 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness tolerance:\u003c\/strong\u003e ±0.2 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eStorage \u0026amp; Handling\u003c\/h2\u003e\n\u003cp\u003eFor optimal performance, store and use at 25 °C and 40–60% relative humidity.
