Hoya UV-IR 49 mm

Hoya has introduced the new Hoya UV & IR Cut Filter in sizes ranging from 49 mm to 82 mm. This specialized filter effectively cuts out both UV rays below 390 nm and IR rays above 700 nm, allowing only the light rays in the visible spectrum to pass through to the camera. This is crucial, as CCD and CMOS sensors are very sensitive to UV and IR rays that lie just outside the visible spectrum, which can negatively affect image quality.

The Hoya UV & IR Cut Filter blocks both UV and IR rays, resulting in clearer and sharper images outdoors. This filter can reduce the effects of atmospheric haze more effectively than a standard UV filter.

The light transmission curve of the Hoya UV & IR Filter illustrates the sharp cut characteristics of the filter glass and coatings, as well as the consistent light transmission in the visible spectrum. This curve shows a more uniform light transmission compared to the nearest competitor, leading to sharper images with greater depth and richer color gradients when using the Hoya UV & IR Cut Filter.
