6″ Optical Spectrometer with Prism
Hands-On Learning Tool for Fundamental Optics
This 6-inch (150 mm) optical spectrometer is a classic educational instrument designed for measuring angles of deviation, refractive index of solids/liquids, and wavelength of light sources using a glass prism or diffraction grating. Ideal for CBSE/ISC school physics practicals, B.Sc. undergraduate labs, and science demonstration kits, it provides students with direct experience in geometric and wave optics principles.
Precision Mechanical Design for Accurate Readings
Built with durable materials for classroom use:
- Vernier scale with 1′ (1 arcminute) resolution
- Rotatable telescope and collimator on a graduated circular table
- Adjustable leveling screws and spirit level
- Includes equilateral glass prism (typically 60°) and optional grating
- Sturdy cast iron base with anti-slip feet
The instrument enables key experiments like:
- Determination of refractive index of glass/liquid
- Angle of minimum deviation
- Dispersive power of prism
- Calibration using sodium lamp or mercury vapor source
Perfect for Curriculum-Aligned Physics Education
Widely used in Indian school boards (CBSE, ICSE, State Boards) and university physics departments, this spectrometer supports NCERT and UGC-recommended lab syllabi. Its manual operation reinforces foundational concepts without reliance on digital interfaces—making it a timeless tool for conceptual clarity.
