Handheld Spectroscope for Clear, Portable Spectral Analysis Key benefits clarity and resolution from optical glass construction. A composite prism and condenser lens inside the vertical tube deliver sharp, well defined spectral lines for accurate observation. Compact and easy to carry. At 10 cm long and 2.4 cm wide, the lightweight blue casing fits in a pocket or lab kit for fieldwork and classroom use. Simple to use and economical. Designed for students, hobbyists, and classroom labs, the spectroscope provides reliable spectral results without complex setup. How it works Point the slit toward a light source and view the dispersed spectrum produced when parallel light beams pass through the prism. The condenser lens helps concentrate light for clearer bands and finer detail. Under fluorescent lighting, distinct mercury emission lines appear on of a continuous spectrum, enabling direct comparison of line and continuous spectra. For solar observation, use reflected sunlight via a mirror rather than pointing the device directly at the sun. Practical applications Classroom demonstrations of emission and absorption spectra for physics and chemistry lessons. Science fair projects that require identification of light sources or comparison of bulb types. Hobbyist exploration of household light sources, lamps, and laboratory light experiments. Specifications Material: Optical glass Size: 10 cm x 2.4 cm (3.94 inch x 0.94 inch) Package includes: 1 Handheld Spectroscope Note: Manual measurement tolerance approximately 1 to 2 cm. What makes this product stand out Optical glass optics combined with a composite prism and condenser lens produce higher resolution than basic plastic models. Portable, intuitive design suitable for beginners and more experienced users who need a compact tool for on the spot spectral observation. Simple to operate, durable in construction, and designed for educational and hobby use, this handheld spectroscope brings clear spectral analysis into classrooms and field settings.
