The 48-643 is a 2.5mm diameter, 4.0mm focal length Plano-Convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This uncoated lens is designed for use in a wide range of applications, particularly where high-quality imaging is required.
The lens's geometry is characterized by a 0.56mm edge thickness and a center thickness of 0.8mm. It boasts an effective focal length (EFL) of 4mm, making it suitable for use in systems where a compact, high-performance lens is required. The lens's curvature is defined by a radius of 3.4mm on the convex side. The back focal length (BFL) is 3.57mm, providing a clearance for the mounting of other optical components or detectors.
The lens is made from the high-quality material n-lasf9 schott, which is known for its excellent optical properties. It is designed to operate at a wavelength of 587.6nm, making it suitable for use in a wide range of applications, from general-purpose imaging to more specialized uses.
Notably, this lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher level of internal reflection, it can also provide a cost-effective solution for applications where such coatings are not necessary.
