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.
