B + W 37mm Digital Pro UV/IR Blocking #486 Glass Filter for Blocking Ultra Violet and Infrared Radiation
Your card will only be charged once item ships.
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.
The Digital Pro Series filters are designed for users of Digital Cameras and Camcorders. The new chromium-colored mounting goes along perfectly with the light, trendy colors of Digital Cameras.
Digital photography gives you advanced capabilities to enhance the picture after it is taken. However one shouldn't forget a very important fact: information which get lost while taking the picture normally even a Computer can't produce afterwards.
