49-114 25 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=25mm; NA=0.5 BBAR 600-1050nm
The 49-114 is a high-precision aspheric lens offered by Edmund Optics, boasting a diameter of 25 mm and a numerical aperture (NA) of 0.5. This lens is designed for use in the near-infrared (NIR) spectrum, specifically at a wavelength of 587.6 nm.
The lens is crafted from L-BAL35, a material from Ohara, ensuring excellent optical performance. The aspheric design of the lens helps minimize spherical aberration, delivering sharp and clear images. The lens has an effective focal length (EFL) of 25 mm, making it suitable for a variety of applications.
The lens features broadband anti-reflection (BBAR) coatings, which span from 600 to 1050 nm. These coatings are applied to both the front and back surfaces of the lens, reducing surface reflections and enhancing transmission.
The geometry of the lens includes an inner radius of 0 mm, an outer radius of 0 mm, and a thickness at the edge of 1.74 mm. The thickness at the center is 7.5 mm. The lens's front surface has the following Seidel coefficients: k1=-1.439137, e=3.42e-05, f=-6.44e-09, g=2.32e-11, h=-3.52e-14, j=0, and l=0.
