43-822 2.78 mm Dia. Ruby Doped Sapphire Ball Lenses Uncoated

The 43-822 is a 2.78 mm diameter ball lens, specifically designed for applications requiring high precision and durability. Manufactured by Edmund Optics, this lens boasts a ruby doped sapphire material composition, ensuring excellent optical performance and resistance to wear and tear.

The lens is uncoated, providing a bare, unaltered surface that can be beneficial in certain applications where coating might interfere with the desired optical properties. However, it's important to note that uncoated lenses may be more susceptible to environmental factors such as dust, moisture, and scratches.

The lens is designed in a ball shape, which provides a unique advantage in terms of light gathering and distribution. The circular geometry allows for a 360-degree field of view, making it ideal for applications such as imaging, illumination, and beam shaping.

The lens is optimized for a wavelength of 587.6 nm, which falls within the visible light spectrum. This makes it suitable for applications involving visible light, such as microscopy, spectroscopy, and optical communication systems.
