L-BAL009 0.5 mm Dia. S-LAH71 Ball Lenses Uncoated

The L-BAL009 is a 0.5 mm diameter Ball Lens, sourced from the renowned optical vendor, Ross Optical. This particular lens is uncoated and fabricated from the S-LAH71 material, a high-quality optical glass produced by Ohara.

The Ball Lens, also known as a spherical lens, is a simple lens with spherical surfaces on both sides. The geometry of this lens, as per the provided data, features a diameter of 0.5 mm, with no inner or outer radius specified, indicating a symmetrical spherical design.

The lens is designed to operate at a wavelength of 587.6 nm, which is within the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging systems, optical communication, and beam shaping.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications where cost, simplicity, or specific optical properties are a priority.
