Spectrometer (7 inch,1 minute) SM – 7

Advanced Student Spectrometer SM-7 is a precision optical instrument designed for accurate measurement of spectral lines and prism angles in physics laboratories. It features a larger 175 mm diameter precision-engraved degree circle for improved accuracy and readability. High-quality large aperture optics provide sharp spectral images, while precision machining ensures smooth rotation and reliable measurements. The dual vernier system allows convenient reading from both sides, making it ideal for student experiments and advanced optical studies.
