Detailed
Felix Glass Co., Limited supplies a precision-ground and polished N-BK7 triangular dispersive prism with a fixed 30mm equilateral cross section and standard lengths of 50mm, 100mm and 150mm. The prism separates white light into the visible spectrum for classroom demonstrations, laboratory light-splitting experiments and optical test platforms. This renovated description retains the original product facts and sequence while organizing the information for US educators, laboratory buyers and optical engineers. Uncoated prisms and custom AR-coated versions can be reviewed for the intended light source and setup. A triangular dispersive prism refracts each visible wavelength by a slightly different angle. When white light enters one polished face and exits another, the beam spreads into a color spectrum. N-BK7 is a practical optical glass for visible-light teaching, general laboratory work and optical instrument assemblies. Shows how visible wavelengths separate through refraction. Supports spectroscopy demonstrations and optical path experiments. Provides a clear physical example for optics courses and science labs. The original technical parameters are retained below in their existing order for engineering review. N-BK7 combines optical uniformity, established refractive properties and useful visible transmission for general-purpose prism applications. For teaching and laboratory setups, it provides a repeatable material basis for observing refraction and dispersion without adding unnecessary material complexity. The fixed 30mm equilateral cross section provides a consistent prism profile, while three standard length choices support different mounts and viewing distances. A 50mm length is practical for compact demonstrations, 100mm provides a larger handling format, and 150mm can suit extended classroom or instrument fixtures. Final selection should account for the light-source diameter, mount clearance, beam position and required illuminated area. Custom lengths can be reviewed when the standard options do not match the assembly. Visible-spectrum demonstrations for physics classrooms and instructional laboratories. White-light splitting and basic spectroscopic experiments on optical benches. Research test setups for studying refraction, dispersion and beam paths. Matching components for teaching kits and simple spectral detection equipment. An uncoated prism is often selected for straightforward spectrum teaching. A custom AR anti-reflection coating can be reviewed when the setup needs reduced surface reflection within a defined wavelength range. Coating decisions should follow the actual source spectrum, incidence angle and observation method. Direct option for general teaching and laboratory light-splitting work. Reviewed by wavelength band and working geometry for the intended system. 30mm triangular cross section with 50mm, 100mm and 150mm standard lengths. Special length and AR coating requirements can be reviewed for OEM projects. Optical performance and finished-part quality are checked before delivery. The original three-year product warranty remains part of the product offering. Production planning can support bulk teaching and laboratory orders. Choose the required length, order quantity and any nonstandard dimensions. Provide the wavelength range and beam size used in the experiment. Confirm uncoated or AR-coated surfaces and the required inspection criteria. Compare related prism formats and adjacent optical components available from Felix Glass Co., Limited. Send the required length, quantity, coating choice, light-source details and delivery needs. Felix Glass can review the specification and prepare a practical quotation for teaching, laboratory or instrument use.N-BK7 Triangular Dispersive Prism for Clear Visible Spectrum Demonstrations
