With high transmission and strong out-of-band blocking, they maintain stable spectral performance across a range of incidence conditions, making them well suited to fluorescence detection, Raman spectroscopy, infrared optics, and laser systems.\u003c\/p\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eFluorescence \u0026amp; Raman spectroscopy\u003c\/li\u003e\n  \u003cli\u003eLaser-line \/ excitation rejection\u003c\/li\u003e\n  \u003cli\u003eSpectral band isolation\u003c\/li\u003e\n  \u003cli\u003eImaging \u0026amp; laser systems\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 OG550\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating:\u003c\/strong\u003e Uncoated (absorptive longpass)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 50.0 × 50.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 2.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStart wavelength:\u003c\/strong\u003e 515 nm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOD:\u003c\/strong\u003e \u0026gt;5.0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTransmission:\u003c\/strong\u003e 90%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlocking range:\u003c\/strong\u003e 200–520 nm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePassband:\u003c\/strong\u003e 610–2500 nm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClear aperture:\u003c\/strong\u003e \u0026gt;90%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallelism:\u003c\/strong\u003e 5 arcmin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface quality:\u003c\/strong\u003e 80-50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface flatness:\u003c\/strong\u003e \u0026lt;2 λ @ 633 nm\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.
