Οπτικό μικροσκόπιο Bresser JUNIOR Biolux SEL 1600x 40x έως 1600x

The Bresser JUNIOR Biolux SEL student microscope is an optical microscope designed for beginners and hobbyists, offering a magnification range from 40x to 1600x. The set includes two wide-field eyepieces (10x and 20x), three objectives (4x, 10x and 40x), an adjustable LED for transmitted and incident illumination with a filter disc and apertures, a smartphone adapter, prepared slides, empty slides and cover glasses, a basic preparation tool set and a hard-shell carrying case. Power is supplied by three AA batteries, enabling use away from mains sockets.

Advantages

The microscope features a Barlow-zoom system integrated into the eyepiece socket that allows continuous magnification adjustment up to 2× via a pull-out auxiliary lens, enabling effective magnifications from 40x to 1600x with the supplied eyepieces and objectives. Dual illumination (transmitted and incident LED) with a filter disc permits precise control of lighting for transparent and opaque specimens. A smartphone adapter enables image capture and sharing, while the hard-shell case stores and protects the instrument and accessories for transport. Battery operation increases portability.

Suitable for

• School lessons and student laboratory exercises
• Home study and hobby microscopy
• Observation of prepared slides and creation of own specimens
• Viewing small opaque objects such as leaves and insects using incident light

How to use

Install three AA batteries in the battery compartment and place the microscope on a stable, level surface. Select an objective and an eyepiece, then use coarse and fine focus to bring the specimen into sharp view. Adjust transmitted LED illumination for thin, transparent slides or use the incident LED plus appropriate aperture and filter settings for opaque objects such as leaves or insects. To vary magnification smoothly, pull out the auxiliary Barlow lens in the eyepiece socket and adjust it as needed. Use the smartphone adapter to align your phone camera with the eyepiece and capture images.

Recommendations

For best results, start observations at the lowest magnification (40×), center and focus the specimen, then increase magnification stepwise. Clean slides and cover glasses before use, handle objectives gently when changing, and store the microscope in the included hard-shell case to protect optics during transport.
