The L-BAL007 is a 0.5 mm diameter Ball Lens, a type of circular lens, sourced from the renowned optical vendor, Ross Optical. This particular model is made from H-K9L material, also known as CGDM, which is a type of glass known for its excellent optical properties.
The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where a natural lens surface is required. However, it's important to note that uncoated lenses can be more susceptible to environmental factors such as dust, dirt, and smudges, which can affect their performance.
The L-BAL007 is designed to work with a wavelength of 587.6 nm, a common wavelength used in various optical applications. The lens's geometry is that of a ball lens, which means it has a spherical surface on both sides. This design can provide a unique optical behavior, such as a high numerical aperture, making it suitable for various applications.
