67-250 15 mm Dia. N-SF5 Precision Aspheric Lens; EFL=9mm; NA=0.83 BBAR 425-675nm
This is the 67-250 15 mm Dia. N-SF5 Precision Aspheric Lens, a high-quality optical component designed for use in a variety of applications. Sourced from the renowned vendor Edmund Optics, this lens boasts a 15 mm diameter and a numerical aperture (NA) of 0.83, making it a versatile choice for many optical systems.
The lens is made from N-SF5 Schott, a high-refractive-index glass that is known for its excellent optical properties. This material, combined with the aspheric design, helps to minimize spherical aberration and other optical distortions, ensuring sharp, clear images.
The lens has an effective focal length (EFL) of 9mm, which determines the distance at which it focuses light. This makes it suitable for use in systems where a compact, high-performance lens is required.
The lens is coated with BBAR 425-675, a broadband anti-reflection coating that reduces surface reflections and increases transmission across the visible spectrum (425-675nm). This coating helps to improve the overall efficiency and performance of the lens.
The lens has a center thickness of 7mm and an edge thickness of 1.35mm. The front and back surfaces of the lens are both coated with the same BBAR 425-675 coating, providing consistent performance and protection.
