Potential Replacement
• The proposed most similiar alternatives have no difference in terms of dimensions.
• The only difference is in a change of the spectral sensitivity:
• F-type filter have a close match for 950 nm emitter but a poor match for the 850nm
• FA-type filter are matching very good for 850 nm and 950 nm emitters
• FA-type filter show a higher ambient light sensitivity than F-type filter due to the wider
sensitivity range towards visible wavelengths
