Stereo microscope Deltaoptical Discovery 30 DO-3661 30x magnification LED illumination

The Deltaoptical Discovery 30 DO-3661 is a stereo microscope that delivers up to 30x magnification with built-in LED illumination. Designed for inspection, education, hobbyists and light laboratory tasks, it provides a stereoscopic three-dimensional view that supports accurate observation and manipulation of small objects. The compact optical head and straightforward controls make the Discovery 30 suitable for coin and stamp examination, electronic board inspection, dissections and general quality control where low-to-mid range magnification and reliable lighting are required.

Advantages

The stereo optical design provides a true 3D image with comfortable working distance for handling specimens and tools. Integrated LED illumination ensures even, cool light with low power consumption and minimal heat transfer to samples. A magnification range up to 30x offers flexibility for close inspection without complex objective changes. The unit’s compact footprint and user-friendly controls make setup and adjustment quick, while stable mechanical construction supports repeatable positioning during routine tasks.

Suitable for

• Hobbyist microscopy and educational demonstrations
• Dissection and biological specimen observation
• Inspection of printed circuit boards and electronic components
• Numismatics and philately (coin and stamp inspection)
• Basic quality control and visual inspection in light laboratory environments

Key specifications

• Optical type: stereo binocular microscope providing stereoscopic 3D viewing
• Maximum magnification: 30x
• Illumination: integrated LED lighting for bright, even illumination
• Working distance: comfortable distance for manipulation and tool access (typical for stereo microscopes)
• Focus control: coarse focus mechanism for quick specimen targeting
• Form factor: compact tabletop design suitable for benchtop use

How to use

Position the Discovery 30 on a stable, level surface and connect the power supply for the LED illumination. Place the specimen on the stage or work surface beneath the objectives and use the coarse focus knob to bring the image into view. Adjust interpupillary distance and diopter settings if available to match the operator’s eyes for a clear stereoscopic image. Use the magnification control to select the desired viewing scale up to 30x and adjust the LED light intensity or angle as needed for optimal contrast and detail.

Usage recommendations

For consistent results, allow the LED illumination to warm up briefly before making critical inspections, maintain the optical surfaces clean and dust-free, and secure small parts with appropriate holders or tweezers to prevent movement during examination. Use appropriate eye protection and follow laboratory safety procedures when working with biological specimens or electronic assemblies.
