88-620 3.0mm Dia. x 12.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-620 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 3mm, making it compact and versatile for various applications. The lens's thickness at the edge is 0.9mm, while its center thickness is 1.08mm, providing a balanced structure for efficient light transmission.
The effective focal length (EFL) of this lens is 12mm, which is the distance from the lens's center to the point at which the light rays converge or diverge. This EFL makes the lens suitable for applications requiring moderate magnification and a relatively wide field of view.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent optical properties, including high transparency and low dispersion. This material ensures the lens delivers sharp and clear images with minimal chromatic aberration.
The lens features VIS-EXT coating on both the front and back surfaces. This coating extends the lens's usable wavelength range from 350nm to 700nm in the visible spectrum, enhancing its versatility and performance in various lighting conditions.
