Swarovski BTX eyepiece module

The Swarovski BTX eyepiece module provides a revolutionary viewing experience, see every fine detail with crystal clear optics. Enjoy hours of viewing thanks to the comfortable forehead rest and angled view.

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 the twilight. The bigger the objective lens diameter, the lighter 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 millimetres. For example, a device with the suffix 10x42 has an objective lens with a diameter of 42 mm.

VARIABLE MAGNIFICATION

Variable magnification makes it possible to adjust the magnification flexibly within a specific range. In contrast to fixed magnification, it allows you to zoom from the lower value to the higher value. However, as the magnification increases, the field of view, i.e. the image section, becomes smaller. Check the precise product name as the number in front of the ‘x’ specifies the magnification. For example, 30-70x95 is a device with a variable magnification from 30x to 70x.

MODULAR SPOTTING SYSTEM

Modular spotting systems make it possible to flexibly combine different components (objective module and eyepiece module). The objective module is the component that faces the object being observed, while the eyepiece module is closest to the observer. Unlike permanent built-in spotting or extendable spotting, modular systems can be adapted to meet special requirements in different situations.

WEIGHT

The weight specifies how heavy or light the device is (in grams or ounces). Do you intend to do a lot of walking? Lightweight equipment is a priority in this case.
