49-097 15 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=11.25mm; NA=0.66 BBAR 425-675nm

This is the 49-097 model from Edmund Optics, a high-precision 15 mm diameter Aspheric Lens made from L-BAL35 material. The lens boasts a 0.66 numerical aperture (NA) and features Broadband Anti-Reflection (BBAR) coating for the 425-675nm wavelength range, ensuring optimal light transmission and minimal loss due to reflection.

The lens's geometry is carefully designed with an inner radius of 0 and an outer radius of 0, providing a balanced optical path. The effective focal length (EFL) is 11.25mm, making it suitable for medium to long-range optical systems. The lens has a center thickness of 7mm and an edge thickness of 1.94mm, offering robustness and stability in its structure.

The aspheric design, represented by the k1 value of -1.076527, significantly reduces spherical aberration, coma, and other optical aberrations, resulting in high-quality imaging with improved resolution and contrast. The front and back surfaces of the lens are coated with BBAR coating, further enhancing its light transmission capabilities.

This lens is an excellent choice for applications requiring high-performance, wide-spectrum optical components, such as beam shaping, laser systems, machine vision, and biomedical imaging. With its reliable performance and versatile specifications, the 49-097 Aspheric Lens is a valuable addition to any optical system.
