B+W 48mm UV/IR Cut (MRC) Filter

B+W 48mm UV/IR Cut (MRC) Filter - This is a clear and colorless filter that interferes with infrared and UV contamination through its multi-layer construction. This filter is recommended for those cameras with CCD sensors that do not have a built-in UV/IR protection system. Without this filter, you would see some unwanted color and sharpness issues caused by the chromatic aberration of the glass that is only balanced for visible light.

This filter is designed with more than 30 layers of interference coatings on one side while the flip side contains the world famous B+W MRC coating.  No increase in exposure is required. The Multi-Resistant Coating (MRC) is harder than traditional B+W glass. This helps prevent scratches as well as being water and dirt repellent.

The reputation of B+W's Schott glass is world renowned. The high production standards combined with a sturdy brass filter ring make B+W filters hard to beat. These filters have a "heft" to them that is impressive. They may feel heavier but the benefit is in the construction and results. Not only is the glass exceptional but so is the seal between the ring and glass. Schott Glass used in the manufacture of this filter is legendary and synonymous with the highest standards of filter production. It comes with a solid 10-year warranty.

The filter ring is made from brass yielding a stronger product. Brass filter rings are also less prone to jamming. In addition, the seal between the glass and filter ring is exceptionally strong giving the filter added strength and durability.

In production, the filter glass is dropped into the empty filter ring from the rear and held in place with a threaded retaining ring; this is a definite advantage over a competitor who uses a spring clip to hold the glass in place. A threaded retaining ring will hold the glass firmly and securely in place to avoid the possibility of rattling and provide perfect parallelity and flatness to your front lens element for ideal optics.

The advantage of additional filters not binding is due to the fact that brass is a very stable metal and does not contract or expand like alloy.

Note! The filter is not suitable for lens systems with an angle of view of more than 60°
