The Swarovski Optik ATX/STX/BTX 115mm Objective Module offers outstanding detail resolution. This device even pushes optical tests to their limits and it is the ultimate benchmark for those who want to see even tiny details in razor-sharp focus.
Objective Lens Diameter
The Swarovski Optik ATX/STX/BTX 115mm Objective 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 10×42 has an objective lens with a diameter of 42 mm.
