SPX026 25.4 mm Dia. x 175 mm FL; Uncoated; Plano-Convex Lens
The SPX026 is a Plano-Convex Lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens boasts a base shape of a circle and is designed for use in systems operating at a wavelength of 589 nm.
The lens has a diameter of 25.4 mm and a thickness at the edge of 3 mm. The center thickness is slightly more, measuring 4.01 mm. The effective focal length (EFL) of this lens is 175 mm, making it suitable for applications that require a longer focal length.
The lens's front surface has a radius of curvature of 80.222 mm, and the back focal length (BFL) is 172.25 mm. The inner radius of the lens is 0 mm, indicating a flat surface.
The lens is made from UVFS material with the ID MAL-1965. It is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces. This may make it more susceptible to scattering and absorption losses, but it can be advantageous in applications where coatings may introduce unwanted effects.
The lens's parameters are all provided in metric units, which is the standard for optical design and engineering. The link provided in the item data indicates that this lens is in stock, ensuring quick delivery for your optical system needs.
