Stereo microscope Deltaoptical DO-3660 — 20x magnification, LED illumination

Deltaoptical DO-3660 is a stereo microscope with 20x magnification and integrated LED illumination, developed for inspection, hobby work and educational applications. The instrument provides a stereoscopic view that preserves depth perception for three-dimensional observation of small objects. Its compact design and straightforward controls make it suitable for tasks such as circuit board inspection, sample preparation and detailed visual examination in classrooms, workshops and light laboratory environments.

Advantages

The Deltaoptical DO-3660 combines fixed 20x optical magnification with even, built-in LED lighting to deliver clear, shadow-reduced images without the need for external light sources. The stereo optical path offers realistic depth perception for accurate manipulation and inspection of small parts. Its compact footprint and simple operation reduce setup time and are convenient for repeated short-term use. The instrument is designed for stable viewing and can be positioned easily over workpieces requiring close visual assessment.

Suitable for

• Inspection and repair of printed circuit boards and electronic components
• Hobbyist model making, jewelry inspection and detailed craft work
• Educational demonstrations and student laboratory exercises
• Biological sample observation requiring stereo vision and surface detail
• Quality control and small-part assembly verification

Key specifications

• Optical magnification: 20x stereo viewing
• Illumination: integrated LED light source for reflected illumination
• Viewing mode: binocular stereo with depth perception suitable for three-dimensional inspection
• Design: compact stand suitable for benchtop use and close-up observation
• Controls: intuitive focus and illumination adjustment for rapid setup

How to use

Place the DO-3660 on a stable, flat surface and position the specimen under the objective. Switch on the built-in LED illumination and adjust light intensity if a control is provided. Use the focus mechanism to bring the subject into sharp stereo view at the fixed 20x magnification. For tasks that require manipulation, ensure adequate working space between the objective and specimen so tools can be used while maintaining comfortable viewing angles.

Usage recommendations

For best results, keep the objective and eyepieces clean and free of dust; use soft lens tissue for cleaning. When inspecting electronic assemblies, ensure proper electrostatic precautions. If long observation sessions are needed, arrange for ergonomic seating and position the microscope at a comfortable height to reduce strain.
