N-BK7 Triangular Dispersive Prism for Clear Visible Spectrum Demonstrations
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.

Direct answer
What Does a Triangular Dispersive Prism Do?
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.
Lab Evaluation
Supports spectroscopy demonstrations and optical path experiments.
Teaching Use
Provides a clear physical example for optics courses and science labs.

Optical selection
Why N-BK7 Works for Visible-Light Prism Experiments
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.
- Suitable for common visible-spectrum demonstrations.
- Available with polished optical faces and controlled geometry.
- Supports standard sizes and drawing-based customization.
- Can be supplied uncoated or reviewed with an AR coating.
Size selection
Choose 50mm, 100mm or 150mm Prism Length
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.
Applications
Applications
School and University Teaching
Visible-spectrum demonstrations for physics classrooms and instructional laboratories.
Laboratory Spectroscopy
White-light splitting and basic spectroscopic experiments on optical benches.
Optical Physics Platforms
Research test setups for studying refraction, dispersion and beam paths.
Educational Instruments
Matching components for teaching kits and simple spectral detection equipment.
Desire
Uncoated or Custom AR-Coated Prism Options
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.
Uncoated Blank
Direct option for general teaching and laboratory light-splitting work.
Custom AR Coating
Reviewed by wavelength band and working geometry for the intended system.
