The 67-150 25.0mm Dia. x 250.0mm FL is a plano-convex lens sourced from Edmund Optics. This lens, with a base shape of a circle, falls under the category of Spherical Lens and is uncoated. The lens has a diameter of 25.0mm, with a thickness at the edge of 2.39mm and a center thickness of 3.0mm. The Effective Focal Length (EFL) of this lens is 250.0mm, making it suitable for applications requiring a longer focal length.
The lens's curvature is defined by a radius of 129.2mm on the curved side, and the Back Focal Length (BFL) is 248.02mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The lens is designed to operate at a wavelength of 587.6nm.
Please note that this lens is uncoated, which means it does not have any anti-reflective coatings. This may result in unwanted reflections, especially in high-light applications. However, uncoated lenses can be advantageous in certain scenarios, such as when minimal reflection is desired or when cost is a significant factor.
