49-553 0.50 mm Dia. Sapphire Half-Ball Lenses Uncoated

The 49-553 is a 0.50 mm diameter Sapphire Half-Ball Lens, uncoated, sourced from the reputable optical vendor, Edmund Optics. This lens, with its unique half-ball shape and circular base, is a versatile component in various optical systems.

The lens's geometry is meticulously designed, featuring a 0.50 mm diameter and a thickness of 0.25 mm. The inner radius is 0, while the outer radius is also 0, indicating a flat surface on the base of the half-ball. The radius of curvature (r1) is 0.25 mm, suggesting a relatively shallow curvature, which could be beneficial in specific optical applications.

The lens is crafted from Sapphire, a material with the ID al2o3 mal-1972-n-o. Sapphire is known for its excellent optical properties, including high transparency and a wide transmission range, making it suitable for use across various wavelengths. In this particular lens, the wavelength of 587.6 nm is specified, although its performance is likely to be consistent across a broader spectrum.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses in certain applications, an uncoated lens can be advantageous in others, offering simplicity, reduced cost, and the potential for custom coatings based on specific application requirements.

The lens's current status is "Valid - in stock", according to the weblink provided, ensuring availability for immediate integration into optical systems.
