Glasses in the following Table are listed in order of increasing index. Glass name shown is from the Schott glass catalog (2000). Other glass manufacturers may assign different names as shown in the Cross Reference Table. Besides refractive index and Abbe number, six digital numerical designation per MIL-G-174 is often used as glass code. For BK7 (n_d=1.5168, V_d=64.17) the six-digit numerical code is 517642.
