The variety of binocular models is as diverse as their range of applications. However, one principle applies to all: the type of use determines the type of binoculars. If you need binoculars for hiking, stalking, daytime hide hunting, driven hunts, or a Sunday walk, you&apos;ll likely choose a model with a compact design and an objective lens diameter between 30mm and 42mm. Binocular models with objective lens diameters exceeding 50mm are typically used for hide hunting or stationary observations.

Which binoculars are the right ones?

Binoculars with Porro prisms can be identified by a noticeable offset between the objective lens and the eyepiece, with the objectives typically positioned outward in the binocular arrangement of the two telescopes. This design is based on the configuration patented by Ernst Abbe in 1893, which laid the foundation for binocular construction. Porro prisms come in two different configurations, with the first type of Porro system being the most prevalent today. From around the 1920s, binoculars with other prism reversal systems were developed and produced in larger quantities. These systems are characterized by a reflective surface shaped like a roof edge. They can be constructed without any offset between the incoming and outgoing optical axes. Typical roof prism systems include the Abbe-K&#xF6;nig, Uppendahl, and Schmidt-Pechan designs, the latter being the most widely used today. Optical performance: Porro prism systems avoid the inherent disadvantage of roof-shaped prism sets, namely polarization effects. These effects in roof prism systems can only be minimized through extremely high precision and the application of phase-correcting coatings on the roof surface. In a Porro prism system, the reflection on the cathetus sides of the prisms utilizes total internal reflection making it almost loss-free. This eliminates the need for sensitive, transmission-reducing mirror coatings. By cementing the two individual prisms together, as employed in systems like those from NOBLEX, the number of optically active surfaces is reduced from 8 to 6. This reduces potential negative effects on image quality while simultaneously increasing light transmission by eliminating two glass-air surfaces. In contrast, a Schmidt-Pechan roof prism system has 10 active surfaces that influence the image. The clear beam passing through the prism system, and the prevention of stray light through appropriate prism mount designs, enable a high-contrast image. The occurrence of bright stray light exiting through the eyepieces (secondary pupils), which even high-quality roof prism systems cannot always entirely avoid, is completely eliminated and ensures high image brilliance. A Porro prism system can handle significantly larger bundles of light, guiding them through the prisms without loss. Typically, for the same objective diameter, the light bundles in Porro prism systems are twice as large as those in roof prism systems and are fully transmitted. This results in a brighter image even toward the outer edges, making Porro prism binoculars better suited for twilight conditions as compared to roof prism designs. (Source: A.

To ensure maximum light transmission, lenses must be coated. However, due to physical limitations, it is impossible to achieve 100% transmission. As a result, residual reflections are visible on binocular lenses, appearing in various colors depending on the type of coating layer. The coloration of an anti-reflective coating is a result of the non-linear behavior of residual reflection across the wavelength spectrum. This residual reflection is primarily influenced by the type of anti-reflection coating (single-layer, multi-layer coating, or broadband anti-reflection), the position of the reflection minimum, the composition of the coating system (material selection, layer thickness, and sequence), the refractive index of the base material, and manufacturing variations (deviations in layer thickness and positioning within the coating chamber). Traditional single-layer coatings with MgF&#x2082; typically exhibit a blue tint. Multi-layer coatings often appear violet but can also show other colors, including blue, if the reflection minimum is shifted towards red. Modern broadband anti-reflection coatings are often slightly green. This is because within the wide spectral range where reflection is very low, the reflection is slightly higher in the middle range (green), which is perceived as a color tone. (Source: A.
