47-343 25.0mm Dia. x 30.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
The 47-343 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 25.0mm, making it suitable for a wide range of optical applications. The lens has a thickness of 1.73mm at the edge and 8.06mm at the center, providing a decent depth for various setups.
The lens's effective focal length (EFL) is 30.0mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. This EFL, combined with the lens's diameter, gives a relatively high f-number, making it suitable for applications that require a greater depth of field.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is coated with EDM VIS-0 STD CURVE on both the front and back surfaces, which enhances its transmission in the visible spectrum (425-675nm). This coating also reduces surface reflections, improving the overall efficiency and quality of the optical system.
