Notch Filter of 488±5nm  

Notch filters (BEF, band inhibition) can transmission most wavelengths, but attenuates light to very low levels in a specific wavelength range (BEF). Notch filters, in contrast to band-pass filters, only inhibit light in a narrower wavelength range. Applications: Laser protection, Raman spectrometer, laser fluorescence analyzer, biomedical laser system, etc. Product Parameter产品参数 Central wavelength (nm) ·  Half-peak bandwidth (nm) Transmission wavelength(nm)   Average transmittance(%)   Cut-off depth Notes 488±5 60±5 365-650 ＞90…
