## Long description

Deltaoptical Biolight 100 DO-3211 is a compact compound microscope with blue LED illumination designed for biological and educational observation. The instrument provides bright, stable lighting and optical magnification suitable for examining prepared slides, cells and thin tissue sections. Its user-oriented mechanical controls and sturdy construction make it appropriate for classroom use, laboratory exercises and hobby microscopy where reliable contrast and focused detail are required.
Advantages
The blue LED light source delivers consistent, low-heat illumination that improves contrast and reduces specimen warming. Precision focusing and a stable mechanical stage allow clear observation at higher magnifications. The microscope’s compact footprint and straightforward controls simplify setup and routine use, while durable optical components provide repeatable image quality for extended use.
Suitable for
Biological and histological slide observation in educational settings
Laboratory practice and routine specimen inspection
Hobby microscopy for students and amateur naturalists
Demonstrations and classroom practicals requiring easy-to-use optics
Key specifications
Optical type: compound microscope suitable for transmitted light observation
Illumination: blue LED light source providing bright, stable illumination with low heat output
Magnification: range supported by standard objective and eyepiece combination for cell and tissue observation
Focus mechanism: coarse and fine focusing for precise image adjustment
Stage: mechanical or fixed stage compatible with standard prepared slides
Construction: compact, robust body designed for classroom and laboratory environments
How to use
Place a prepared slide on the stage and secure it with the stage clips or mechanical stage controls. Switch on the blue LED illumination and adjust brightness to a comfortable level. Start observation using the lowest-power objective to locate the area of interest, then rotate to higher magnification and use coarse and fine focus controls to obtain a sharp image. Adjust illumination intensity and condenser position as needed to optimize contrast and resolution for the specimen under study.
Usage recommendations
For consistent results, handle optical surfaces with lens-cleaning tissue and store the microscope in a dust-free environment when not in use. Use slides and coverslips of appropriate thickness and keep illumination at levels that avoid unnecessary heat exposure to sensitive biological samples.
