Like F2, it is a flint glass that offers excellent performance in the visible and NIR spectral range. It offers a high refractive index and low Abbe number, making it excellent for use in an equilateral dispersive prism.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePolarization Effects\u003c\/strong\u003e\u003cbr\u003eFor P-polarized light (blue line) incident on a dispersing prism at the angle of least deviation, the graph to the right shows that only a small percentage of the P-polarized light is reflected at the surface. Thus, for this polarization, the transmission through a prism fabricated from N-F2 will be excellent even though there is no AR coating on the surface.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eN-SF11, F2, and N-F2\u003c\/strong\u003e\u003cbr\u003eBoth N-SF11 and F2 offer excellent performance in the visible range. When compared to each other, F2, which is a flint glass, has superior chemical resistance and better transmission than N-SF11. For instance, at 420 nm the theoretical internal transmittance of a 10 mm thick piece of F2 is 0.995, whereas for the same thickness of N-SF11, the internal transmittance is 0.910. If the glass is increased to a thickness of 25 mm, these internal transmission values decrease to 0.987 and 0.790, respectively. With high indices of refraction and low Abbe Numbers V\u003csub\u003ed\u003c\/sub\u003e, N-SF11 and F2 provide maximum dispersive power.\u003c\/p\u003e\n\u003cp\u003eN-F2 is a RoHS compliant material that has been engineered to have nearly identical optical properties as F2. At 633 nm, both N-F2 and F2 have an index of refraction of 1.617, and they have nearly identical Abbe numbers of 36.43 and 36.37, respectively.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable class=\"SpecTable\" width=\"375\" cellspacing=\"0\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth id=\"th1289CBB80000\"
