B+W 40.5mm Digital Pro 486 UV/IR Blocking Glass Filter
This B&W 40.5mm Digital Pro 486 UV/IR Blocking Glass Filter has a completely colorless glass carrier coated with a number of extremely thin, partially reflecting layers with precisely computed thicknesses, similar to MC coating (multi-coating).
The B&W Filter 486 does not block by means of absorption, but by interference of the unwanted UV and IR radiation that is repeatedly reflected between these layers affecting the wavelengths on both sides of the visible spectrum with a steep cut-off.
B&W Digital Pro filters are characterized by a brushed chrome brass ring that will stylishly blend with today's modern digital cameras for both still and video formats.
- Used mainly on digital and video cameras with CCD sensors without an integrated IR protection filter, because the IR sensitivity of the CCD sensor would otherwise cause color changes and lack of sharpness
- That unsharpness results from the chromatic aberration of the lenses that are only corrected for visible light
- In the visible range, the transmission curve is very high and straight
