    AI Overview
    Optical grade glass is categorized by refractive index (
    ndn sub d
    𝑛𝑑
    ) and Abbe number (
    Vdcap V sub d
    𝑉𝑑
    ), with primary types including crown (lower index, high Abbe) and flint (higher index, low Abbe) glasses. Key materials include N-BK7, fused silica, and specialized lanthanum glass for high-index, low-dispersion applications. Major manufacturers (Schott, CDGM, Ohara) define these, with popular types ranging from
    𝑛𝑑
    =1.434
     (CaF
    2sub 2
    2
    ) to
    4.0034.003
    4.003
     (Germanium). 
    Common Optical Glass Types and Materials 
    • N-BK7 (517642): The most common borosilicate crown glass for general-purpose lenses and windows.
    • Fused Silica (JGS1): Excellent for UV transmission and high thermal shock resistance.
    • Calcium Fluoride (CaF
      2sub 2
      𝟐
      ):       Often used in high-performance IR and UV applications, lowest index listed (1.434).
    • N-SF6 (805254): A dense flint glass offering a high refractive index (
      1.8051.805
      1.805
      ).
    • Lanthanum Glasses (e.g., N-LASF9, N-LAH79): High refractive index with low dispersion for advanced imaging.
    • Germanium & Silicon: Preferred for infrared (IR) applications, having the highest refractive indices (4.003, 3.422).
    • BOROFLOAT® 33: Borosilicate glass for high-temperature stability. 
    Key Manufacturer Classifications 
    • CDGM: Offers a wide range including H-K9L (similar to N-BK7) and environmentally friendly lanthanum-based glasses.
    • Schott: Known for "N-" prefix (lead-free) glasses like N-BK7, N-SF11, and ZERODUR®.
    • Ohara: A major manufacturer providing popular types like S-FPL51 (low dispersion). 
    Key Properties Checklist 
    • Refractive Index (
      ndn sub d
      𝒏𝒅
      ):       Determines light bending strength (ranging from 1.43 to 4.0+).
    • Abbe Number (
      Vdcap V sub d
      𝑽𝒅
      ):       Determines dispersion (low dispersion
      >50is greater than 50
      >50
      ).
    • Homogeneity/Bubble Grade: Critically important for high-performance imaging systems.
