B + W 77mm UV/IR Blocking #486 Wide Angle Slim Mount Glass Filter for Blocking Ultra Violet and Infrared Radiation

About this item

This B+W Interference 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.

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.

It is especially recommended for CCD applications where digital image sensors have not been fitted with an IR protection filter.
This filter is completely clear and it requires no increase in exposure. Its filter factor is 1.
