Product Description

These ball lenses have an even higher index of refraction than our LaSFN9 ball lenses, providing a shorter back focal length, which simplifies fiber coupling. Other uses include endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications. S-LAH79 (Ohara) has Abbe Number of 28.3, density of 5.23g/cm3 and coefficient of linear expansion of 6.0μm/m°C (-30 to 70°C).
The Half-Ball Lens simplifies system integration.
For general information about ball lens, as well as how to calculate the NA and Focal Length please check our technical article Understanding Ball Lenses.
