89-436 25mm Dia. N-BK7 Hyperbolic Aspheric Lens; EFL=50mm; NA=0.25 Laser V-Coat 633nm
This is a high-quality aspheric lens from the renowned optical vendor, Edmund Optics. The lens, cataloged under the number 89-436, is designed for use with a wavelength of 633nm and features a laser V-coat for enhanced performance.
The lens has a base shape of a circle and is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The lens has a diameter of 25mm and a thickness of 1.49mm at the edge, while the center thickness is 4.3mm.
The lens's geometry is intricately designed with an inner radius of 0mm, an outer radius of 0mm, and a best form aspheric surface. The effective focal length (EFL) is 50mm, and the numerical aperture (NA) is 0.25. The lens's front surface is coated with an edm las v-coat 633, and the back surface also features the same coating for consistent performance.
The lens's aspheric shape, defined by its k1 value of -2.295475, provides superior optical performance compared to traditional spherical lenses. This makes it ideal for applications that require high precision and accuracy.
The lens is currently in stock and available for immediate purchase through the provided weblink.
