35-708 2.5mm Dia. x 4.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
This is a 2.5mm diameter, 4.0mm focal length Plano-Convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. The lens is made from the high-quality material n-lasf9 schott, which is known for its excellent optical properties.
The lens features a VIS-EXT coating on both the front and back surfaces, which extends its usable wavelength range from 350nm to 700nm. This makes it suitable for a wide range of applications, including but not limited to, machine vision, biomedical imaging, and beam shaping.
The lens has a center thickness of 0.8mm and an edge thickness of 0.56mm, providing a good balance between weight and optical performance. The inner and outer radii are both 0, indicating a flat surface on the planar side of the lens. The effective focal length (EFL) is 4mm, and the back focal length (BFL) is 3.57mm.
The lens is spherical in shape, which is a common and versatile geometry in optical systems. It is available in stock, as indicated by the valid weblink status, making it a reliable choice for your optical design needs.
