The 15x56 SLC Binoculars from Swarovski combine extra-low dispersion (HD) glass elements and a range of proprietary optical coatings with a weather-resistant magnesium-alloy housing to create a multi-purpose set of glasses that delivers impressive image quality and durability. This configuration of the SLC displays an immersive 62° apparent viewing angle; a long 16mm eye relief and multi-position twist-up eyecups enable a comfortable viewing distance for almost any observer.
Swarovski uses an Abbe-Koenig prism design for the 56mm SLC model, which maintains a streamlined form factor without sacrificing image quality. The prisms are phase corrected to enhance sharpness and reduce chromatic aberration. And each of the fluorite-containing HD glass elements is finished with multiple layers of SWAROTOP anti-reflective lens coating. Resulting images transmitted by the SLC optical path are rich with detail and saturated with lifelike color.
