basic information
This is a ball lens manufactured using high refractive index glass S-LAH79. Due to its high refractive index, it focuses at a shorter distance. It is expected to simplify systems for fiber coupling applications. Theoretically, a ball lens with a refractive index of 2.0 minimizes spherical aberration. It is ideal for use in endoscopes, barcode scanning, preform materials for aspheric lenses, and sensor applications. The Abbe number of S-LAH79 is 28.3, its specific gravity is 5.23g/cm³, and its thermal expansion coefficient is 6.0 x 10^-6/°C (@-30~+70°C).
