SLB-40B-100N 40.0 mm Dia. x -99.7 mm FL; Double-Concave Lens Uncoated
The SLB-40B-100N is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed for use in a wide range of optical applications, boasts a diameter of 40.0 mm and a focal length of -99.7 mm, making it a versatile choice for many setups.
The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry, with a center thickness of 2 mm and an edge thickness of 5.9 mm. The inner and outer radii are both 0, indicating a uniform curvature throughout the lens.
The SLB-40B-100N is uncoated, which means it does not have any additional layers to enhance its optical properties. This can be beneficial in certain applications where a specific coating is not required or desired. However, it's important to note that uncoated lenses may be more susceptible to environmental factors such as dust and moisture.
The lens is designed to work with a wavelength of 546.1 nm, making it suitable for use in a variety of applications that operate within this wavelength range.
