In optics, the flatness of glass is crucial because it affects how light is transmitted and reflected, which in turn influences the quality of the images produced. When using a camera filter, the presence of Newton's rings in the flatness testing can significantly degrade the actual image quality. Whether or not flatness can be maintained without the appearance of Newton's rings greatly affects the quality of the product.
What do photographers complain about Polarizers?
Let's explore what users complain about polarizers and how Marumi clears the hurdles that have long frustrated photographers in finding the best-suited polarizer for each individual.
FAQ: I saw other manufacturers claim better reflectance. What's difference?
Marumi’s factory lab research demonstrates a consistent performance with an average reflectance of 0.18% across the visible spectrum (400-700nm). This isn't just a one-off peak performance but a steadfast guarantee across all wavelengths that matter.
