48-431 4.76 mm Dia. Sapphire Half-Ball Lenses Uncoated

The 48-431 is a 4.76 mm diameter sapphire half-ball lens, uncoated, sourced from the renowned optical component vendor, Edmund Optics. This lens is a unique combination of a circular base shape and a half-ball geometry, designed to cater to specific optical requirements.

The lens's geometry is meticulously crafted, with a diameter of 4.76 mm and a thickness of 2.38 mm. The half-ball shape, defined by a radius (r1) of 2.38 mm, is a distinctive feature that sets this lens apart. The inner and outer radii are both zero, indicating a uniform curvature throughout the lens's surface.

The lens is made from high-quality sapphire, identified by the Material ID 'al2o3 mal-1972-n-o'. Sapphire is a highly durable and scratch-resistant material, making it an ideal choice for applications requiring robust and long-lasting optical components.

The lens is designed to operate at a wavelength of 587.6 nm, making it suitable for a wide range of optical systems. It is uncoated, offering users the flexibility to apply their preferred coatings based on their specific application requirements.
