43-831 6.35 mm Dia. Sapphire Ball Lenses Uncoated

The 43-831 is a Ball Lens with a 6.35 mm diameter, sourced from the reputable optical components vendor, Edmund Optics. This lens boasts a circular base shape, making it suitable for a wide range of applications.

The lens is crafted from Sapphire, a material identified as al2o3 mal-1972-n-o in the Material ID. Sapphire is known for its exceptional hardness, second only to diamond, and its high resistance to scratching and thermal shock. These properties make it an ideal choice for applications requiring durability and stability.

The 43-831 operates at a wavelength of 587.6 nm, which is within the visible light spectrum. This wavelength range is commonly used in applications such as microscopy, spectroscopy, and laser systems.

Notably, this lens is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance certain properties of a lens, such as reducing reflectance or increasing transmission, an uncoated lens can be advantageous in certain applications where these properties are not required or desired.
