49-113 25 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=18.75mm; NA=0.66 BBAR 600-1050nm

The 49-113 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 25 mm, is constructed from L-BAL35, a material specifically engineered by Ohara for exceptional optical performance. The lens boasts a numerical aperture (NA) of 0.66, indicating a wide acceptance angle and high light-gathering capability.

The lens's effective focal length (EFL) is 18.75mm, suggesting a moderate magnification and field of view. The aspheric design of the lens helps to reduce spherical aberration, a common optical issue that can lead to distorted images. This is particularly beneficial in applications that require high resolution and accuracy, such as imaging, metrology, and beam shaping.

The lens is coated with BBAR 600-1050, a broadband anti-reflection coating that enhances transmission across the visible and near-infrared spectrum (400-1100nm). This coating reduces surface reflections, improving the overall efficiency and quality of the optical system.
