Optical N-SF11 Rhomboid Prism
The N-SF11 rhomboid prism is a parallelogram-shaped optical component made from N-SF11(H-ZF13) flint glass, known for its high refractive index and strong dispersion properties. These characteristics make it ideal for applications requiring compact optical path design or precise chromatic dispersion control.
