What to consider when choosing your binoculars

Objective lens diameter

The objective lens diameter specifies how much light can enter the optics. This makes it a key factor in an instrument’s performance, for example, in twilight. The bigger the objective lens diameter, the more light the objective lens can capture. The darker the surroundings, the larger the objective lens diameter needs to be. Check the precise product name as the number after the ‘x’ specifies the objective lens diameter in millimeters. For example, a device with the suffix 10x42 has an objective lens with a diameter of 42 mm.

For distortion-free images, SWAROVSKI OPTIK has also opted for the SWAROVISION technology for the NL Pure 10x42. The innovative field flattener lenses offset the lens curvature to provide razor-sharp images.

Brief description of the SWAROVISION technology

The key feature of the ground-breaking SWAROVISION technology is the field flattener lenses which offset the curvature of the field of view and provide edge sharpness. This means the complete image stays sharp from the middle of the field of view all the way to the edges. There is no need to refocus if your eye moves in the image, you can immediately see every detail in absolute clarity. The special coating on the lenses in combination with the inert gas filling ensures color fidelity.

The NL Pure series

The binoculars in the NL Pure series offer an enormous field of view all the way to the edges. Thanks to the wasp waist, each optical device sits ergonomically in your hand, making it a trusted companion even over extended periods of use. The amazing quality provided by SWAROVISION and the field flattener lenses guarantees precise and razor-sharp images with no distortion.
