46-228 2.38 mm Dia. Ruby Doped Sapphire Ball Lenses Uncoated

The 46-228 is a 2.38 mm diameter ball lens, sourced from the reputable vendor Edmund Optics. This lens, specifically designed for optical applications, boasts a circular base shape and is uncoated. The item data indicates that it is a Ruby Doped Sapphire Ball Lens, which suggests that it is made from aluminum oxide (Al2O3) and doped with ruby for specific optical properties.

The lens's geometry is defined by its diameter, with no inner or outer radius specified, suggesting a uniform spherical shape. The wavelength of 587.6 nm indicates the lens's intended use in the visible light spectrum. However, the item data does not provide information on the lens's specific refractive index, dispersion, or Abbe number.

As a ball lens, it is designed to focus or collimate light in a symmetrical, omnidirectional pattern. This makes it suitable for applications such as fiber optics, endoscopy, microscopy, and other scenarios requiring efficient light manipulation.

Please note that the lens is uncoated, which may affect its performance in certain applications. Coatings can be used to enhance transmission, reduce reflection, or protect the lens surface. The absence of a coating may necessitate additional considerations in your application.
