ACL5040U-A 50 mm Aspheric Condenser Lens; f=40 mm, NA=0.60 AR 350-700nm
The ACL5040U-A is a high-quality aspheric condenser lens, designed and manufactured by Thorlabs. This lens boasts a focal length of 40 mm, making it suitable for a wide range of optical applications. The lens is constructed from B270 Schott glass, a popular material known for its excellent optical properties and durability.
The lens features a 50 mm diameter, providing a generous aperture for efficient light collection and transmission. The aspheric design of the lens helps to reduce spherical aberration, enhancing the overall image quality. The lens has a numerical aperture (NA) of 0.60, indicating a high light-gathering capability.
The ACL5040U-A is coated with Thorlabs' anti-reflection coating, which is designed to minimize surface reflections and increase transmission in the 350-700 nm spectral range. This makes the lens ideal for use in applications such as fluorescence microscopy, where high transmission and low autofluorescence are crucial.
The lens has a thickness of 2.6 mm at the edge and 21 mm at the center. The inner and outer radii are 0 mm, suggesting a flat profile that can be beneficial in certain optical configurations. The effective focal length (EFL) is 40 mm, and the back focal length (BFL) is 26 mm.
