Antlia Edge 4.5nm OIII Narrowband Filter - 31 mm Unmounted type-telescope-eyepieces better facilitating the imaging processAntlia OIII Edge Filter Highlights: Type: Oxygen III (OIII) FWHM: 4. 5 nm CWL: 500. 7nm Filter Thickness: 2 mm + 0. 05 mm Peak Transmission: 90% Size: 31 mm Unmounted Antlia OIII EDGE narrowband filter optimizes the FWHM (full width half maximum) to 4. 5nm bandpass. The suppression of optical density (OD)5 on unwanted wavelengths and the excellent transmittance characteristics found in the Antlia 3nm Pro series has been incorporated into the 4. 5nm
