Tabletop Spectroscope with Fiber

The spectroscopic unit is based on a high-quality imported prism, ensuring good light transmission, a sharp spectrum, and sufficient resolution to identify absorption lines and estimate wavelengths.
The integrated scale allows direct readings from 400 to 700 nm with an indicative accuracy of ±2 nm, making it suitable for comparative analysis and laboratory quality control.

The light source is designed to offer two operating modes (powerful transmitted light and cold-light source), with a lamp holder engineered for safe and easy bulb replacement.
The system uses a high-intensity halogen lamp mounted in a low-heat-emission dome, combined with a 600 mm self-locking fiber optic tube and an internal cooling fan. This configuration provides strong illumination while minimizing the risk of overheating the sample or the fiber.

From an ergonomic standpoint, the instrument features two grooves for sample positioning, side holes for gem clips, and an adjustable prism support with slit and variable focus. These elements ensure easy alignment and consistent, repeatable measurements in both professional and educational laboratories.
