84-125 2 mm Dia. N-PSK53A/N-LASF9 Achromatic Doublet; EFL=4mm VIS 0° 425-675nm
The 84-125 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 2 mm diameter, is designed for use in the visible light spectrum, specifically between 425 and 675 nanometers. The lens boasts an effective focal length (EFL) of 4mm, making it suitable for a wide range of optical applications.
The lens is constructed from two types of Schott glass, N-PSK53A and N-LASF9, which are carefully selected to minimize chromatic aberration, a common issue in optical systems. The lens's geometry is meticulously designed, with an inner radius of 0mm, an outer radius of 0mm, and a thickness edge of 1.72mm. The center thickness is 1mm, while the front and back surfaces are coated with Edmund Optics' standard VIS-0 coating, which enhances transmission in the visible spectrum.
The 84-125 is a multiplet lens, meaning it is composed of multiple elements. This design allows for more precise control over the optical properties of the lens, resulting in improved image quality and system performance. The lens is currently in stock and available for immediate purchase through the Edmund Optics website.
