110-0257E 25.4 mm Dia. x 900 mm FL; Uncoated; Plano-Convex Lens

The 110-0257E is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 900 mm. This lens is sourced from EKSMA Optics, a renowned vendor in the optical components industry. The lens is made of BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including a low refractive index and low dispersion.

The lens's geometry is characterized by its plano-convex shape, where one side is flat (plano) and the other side is curved (convex). The thickness at the edge of the lens is 2.8 mm, while the thickness at the center is 3 mm. The lens's inner and outer radii are both zero, indicating a simple convex curve on one side.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings. This can be advantageous in certain applications where the natural properties of the glass are desired. However, it's important to note that uncoated lenses can suffer from reflective losses, which can be significant at certain wavelengths.

The lens is designed to operate at a wavelength of 546 nm. This wavelength falls within the visible light spectrum, making this lens suitable for applications involving visible light.
