The L-BAL055 is a 2.5 mm diameter Ball Lens, part of Ross Optical's extensive catalog of optical elements. This lens, made from N-BK7 glass, is a prime example of Ross Optical's commitment to quality and precision.
The Ball Lens, also known as a spherical lens, is a simple lens with spherical surfaces on both sides. The lens's geometry is defined by its diameter, which, in this case, is 2.5 mm. The lens's inner and outer radii are both zero, indicating a perfect sphere.
The material of the lens, N-BK7, is a borosilicate crown glass commonly used in optical systems due to its excellent optical properties. It has a low refractive index and low dispersion, making it ideal for a wide range of applications.
The lens is designed to operate at a wavelength of 587.6 nm, which is in the visible light spectrum. This wavelength corresponds to the color yellow, indicating that this lens could be used in systems designed to manipulate yellow light.
Notably, the lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflection, increasing transmission, or protecting the lens surface. However, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
