basic information
This is a hemispherical lens made using high refractive index glass S-LAH79. Due to its high refractive index, it focuses at a shorter distance. The hemispherical lens, which is half the shape of a ball lens, has the advantage of being easier to join to the end face of a fiber optic than a ball lens. It is ideal for fiber optic communication, endoscopes, and SIL (Solid Immersion Lens) for high NA objective lenses. 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).
