## Long description

Deltaoptical DO-3800 is a compound microscope designed for educational, hobby and basic laboratory use. With an optical magnification range from 40× to 1000×, the DO-3800 enables observation of prepared slides and small specimens across multiple objective steps. The instrument is intended for visual study of biological samples, thin sections and other small objects that require transmitted light and higher magnification.
Advantages
The DO-3800 combines a multi-step magnification range with a stable mechanical stage and coaxial focusing, allowing precise focusing at both low and high magnifications. Its optical system delivers clear image detail for routine classroom demonstrations and amateur microscopy. The compact design and user-oriented controls make the microscope straightforward to set up and operate for students and hobbyists.
Suitable for
 Biology classes and student laboratory exercises
 Amateur microscopy and hobby observation
 Basic educational demonstrations and slide study
 Routine examination of prepared slides and small transparent specimens
Key specifications
 Optical magnification range: 40×–1000× across multiple objective steps
 Compound microscope configuration with transmitted light illumination
 Mechanical stage suitable for prepared slides
 Coaxial focus controls for coarse and fine adjustment
 Eyepiece and objective combination delivering high magnification capability
How to use
Place a prepared slide on the stage and secure it using the stage clips or slide holder. Start observation at the lowest magnification to locate the area of interest, then switch to higher objective steps to increase magnification up to 1000× as needed. Use the coarse focus to bring the image into approximate focus, then refine with the fine focus control. Adjust the illumination intensity to obtain a clear, evenly lit field of view and reposition the condenser if necessary for better contrast.
Usage recommendations
For routine educational and hobby use, begin each session with low magnification to center the specimen, then progressively increase magnification. Clean lenses with appropriate lens tissue and store the microscope covered and in a dry place when not in use to maintain optical performance.
