LA1274 N-BK7 Plano-Convex Lens; Dia:30.0 mm; f=40.0 mm Uncoated

The LA1274 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 30.0 mm, is designed for use in a wide range of optical systems, offering excellent performance and reliability.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The lens has a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). This design is often used to focus or collimate light in optical systems.

The LA1274 lens has a focal length of 40.0 mm, which is the distance between the lens and the point where it focuses or collimates light. This makes it suitable for use in systems where a longer focal length is required. The lens has a thickness of 2.5 mm at the edge and 9 mm at the center, providing robustness and stability in operation.

The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. While this can result in a lower transmission rate and increased susceptibility to environmental factors, it also means the lens has a broader wavelength range, making it suitable for use in a wide range of applications.

According to the vendor's website, the LA1274 lens is currently in stock, indicating its availability for immediate purchase and use. The website also provides further technical specifications and application notes, which can be useful for those considering this lens for their optical system.
