43-828 5.55 mm Dia. Ruby Doped Sapphire Ball Lens Uncoated

The 43-828 is a 5.55 mm diameter ball lens, specifically designed for use in optical systems that require a spherical lens element. This lens is manufactured from ruby doped sapphire, a material with the chemical formula Al2O3, and is renowned for its exceptional hardness and resistance to scratching. The ruby doping enhances the lens's performance in specific wavelength ranges, making it particularly suitable for applications in the visible spectrum.

The lens is uncoated, offering a bare, unaltered surface that allows for maximum light transmission while minimizing reflection losses. However, this also means that the lens may be more susceptible to environmental factors such as dust, moisture, and fingerprints, which can affect its performance. Therefore, it is recommended to handle the lens with care and clean it regularly using appropriate lens cleaning solutions.

The lens is sourced from Edmund Optics, a leading supplier of optical components, ensuring high quality and reliability. According to the vendor, the lens is currently in stock, indicating its availability for immediate purchase and delivery. The vendor's website also provides further technical specifications and application notes, which can be useful for those considering this lens for their optical systems.
