The 49-554 is a 2.50 mm diameter Sapphire Half-Ball Lens, uncoated, available from Edmund Optics. This lens is a circular half-ball shape, designed for specific optical applications.
The lens has a diameter of 2.50 mm and a thickness of 1.25 mm, making it a compact and lightweight option. The radius of curvature (R1) is 1.25 mm, indicating a relatively steep curvature. The inner and outer radii are both 0, suggesting a simple, half-ball design.
The lens is made of Sapphire, specifically identified as al2o3 mal-1972-n-o in the material database. Sapphire is a highly durable and scratch-resistant material, making it ideal for applications that require high precision and longevity.
The lens is designed for use with a wavelength of 587.6 nm, which is in the visible light spectrum. This makes it suitable for applications in fields such as imaging, spectroscopy, and beam manipulation.
Notably, the lens is uncoated. This means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. While this may limit its performance in certain applications, it can also make it a more cost-effective option.
