B + W - 43mm Basic 486M MRC UV/IR Cut Filter

With the B+W 43mm Basic 486M MRC UV/IR Cut Filter, photographers can effectively combat the intrusion of unwanted UV and infrared light components that can compromise image quality. This high-quality filter is engineered with a sharp cut-off absorption mechanism, ensuring the prevention of color casts and blurring, particularly crucial for digital cameras where the IR barrier in front of the image sensor may exhibit residual transmittance.Unlike conventional filters, the 43mm Basic 486M MRC UV/IR Cut Filter achieves this not through absorption via colored glass, but through an innovative interference method. This involves a series of wafer-thin, partially reflecting layers, each with a precisely calculated thickness, designed to filter out the unwanted light spectrum.The B+W 43mm Basic 486M MRC UV/IR Cut Filter is clear and colorless, ensuring no need for exposure adjustment. Its durable construction allows it to be left on the lens permanently, serving as a reliable protection filter. Enhanced with MRC coating, this filter offers improved light transmission and reduced reflections.Ideal for lenses with an aperture angle up to 60 degrees, the B+W 43mm Basic 486M MRC UV/IR Cut Filter operates on the principle of interference filter, which results in an aperture angle-dependent color influence. As the angle of the incident light increases, it drifts towards blue, ensuring that for wide-angle lenses with an aperture angle larger than 60 degrees, the color reproduction at the image edge maintains a subtle bluish tint. This innovative filter is a valuable tool for photographers seeking to enhance color accuracy and image clarity.
