This is a 25.4 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics, featuring a focal length of 500mm and made from N-BK7 Schott glass. The lens is uncoated, meaning it does not have any additional anti-reflective or protective coatings.
The lens has a base shape of a circle and is spherical in geometry. The thickness at the edge of the lens is 3.7mm, while the thickness at the center is 4mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other.
The lens is mounted, making it ready for immediate use in optical systems. According to the vendor's website, the lens is currently in stock, making it readily available for purchase and delivery.
The lens is designed to operate at a wavelength of 588nm. This makes it suitable for use in applications that operate within this wavelength range, such as certain types of lasers or monochromatic lighting systems.
