Breaking Down the Features of Bresser Erudit Basic Mono 40x-400x Monocular

Specifications

The Bresser Erudit Basic Mono 40x-400x Monocular boasts a variable magnification ranging from 40x to 400x. This is achieved through a combination of a WF 10x eyepiece and three objective lenses: 4x, 10x, and 40x. The instrument is equipped with a condenser, which is crucial for directing light through specimens, thereby enhancing image contrast and detail.

Illumination is provided by a battery operated LED light source, offering flexibility without the need for a power outlet, which is particularly useful in field or remote lab settings. The monocular is also supplied with a carry case and a box containing slides and 5 prepared slides, providing a ready-to-go starting kit for immediate observation.

The 40x-400x magnification range makes this optic suitable for a wide array of tasks, from observing larger specimens like insect parts or textile fibers at lower powers to examining detailed cellular structures at the highest magnification. The inclusion of a condenser significantly elevates its capability beyond basic illuminated magnifiers, allowing for better control over light intensity and angle, which is vital for resolving fine details in transparent or semi-transparent samples. The battery operated LED offers convenience for mobile use.

Performance & Functionality

In its primary role, the Bresser Erudit Basic Mono performs admirably.
