L-BAL085 4 mm Dia. N-BK7 Ball Lenses Uncoated

The L-BAL085 is a ball lens with a 4 mm diameter, sourced from the reputable optical vendor, Ross Optical. This lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The N-BK7 glass, specifically from Schott, ensures high-quality performance and durability.

The lens is designed in a ball shape, which is a sphere with equal curvature on all sides. This design provides a wide field of view and minimal optical aberrations, making it ideal for various applications. The lens's geometry, including its inner and outer radii, is optimized for 587.6 nm wavelength, which is the green light wavelength in the visible light spectrum.

Notably, the L-BAL085 lens is uncoated. While coatings can enhance the lens's performance by reducing reflection, increasing transmission, or protecting the lens surface, an uncoated lens offers simplicity and cost-effectiveness. It is essential to consider the specific requirements of your application when deciding between coated and uncoated lenses.
