This is a high-precision aspheric lens, catalog number 66-324, offered by the renowned optical vendor, Edmund Optics. The lens is designed with a base shape of a circle and is constructed from L-BAL35 material, a product of Ohara. The lens is optimized for a wavelength of 587.6 nm, making it suitable for a wide range of applications that operate within this spectrum.
The lens geometry is meticulously designed, featuring an inner radius of 0 mm, an outer radius of 0 mm, a diameter of 40 mm, and a thickness at the edge of 6.39 mm. The effective focal length (EFL) is 40 mm, and the numerical aperture (NA) is 0.5. The lens is coated with BBAR 425-675 nm on both the front and back surfaces, ensuring high transmission and minimal reflection across the specified wavelength range.
The aspheric design of the lens, characterized by the coefficients k1=-0.622238, r1=24.681 mm, and r2=400 mm, provides superior image quality and minimizes spherical aberration. The thickness at the center of the lens is 15.5 mm, and the front and back surfaces are free from any tilt or decenter.
