46-121 3.18 mm Dia. Sapphire Ball Lenses Uncoated

The 46-121 is a 3.18 mm diameter Sapphire Ball Lens, uncoated, sourced from the reputable optical vendor, Edmund Optics. This lens, classified under the category of Ball Lenses and sub-type Ball Lens, is characterized by its circular base shape, making it suitable for a wide range of applications.

The lens boasts a diameter of 3.18 mm, ensuring a substantial surface area for light transmission. The geometry of the lens is defined by its inner radius and outer radius, both of which are zero, indicating a true spherical shape. This geometry ensures uniform light distribution and minimal distortion, making it ideal for applications requiring high-precision optical performance.

The lens is crafted from Sapphire, a high-quality material with the material ID al2o3 mal-1972-n-o. Sapphire is known for its exceptional hardness, second only to diamond, making it highly resistant to scratches and abrasions. It also exhibits excellent thermal shock resistance and chemical durability, making it suitable for harsh environments.

The lens is designed to operate at a wavelength of 587.6 nm, making it suitable for a wide range of applications, including but not limited to, imaging, illumination, and beam shaping. The uncoated nature of the lens implies that it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, this does not affect its performance in applications where such enhancements are not required.
