BICV304 38 mm Dia. x -150 mm FL; Uncoated; Double-Concave Lens
The BICV304 is a high-precision double-concave lens, 38 mm in diameter and featuring a focal length of -150 mm. Manufactured by WTS Photonics, this lens is designed for use in a variety of optical applications, offering excellent performance and reliability.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes it ideal for applications that require high light transmission and minimal chromatic aberration. The lens is uncoated, providing a cost-effective solution for applications where coating is not necessary.
The geometry of the lens is characterized by its double-concave shape, with a center thickness of 3 mm and an edge thickness of 5.34 mm. The inner and outer radii are both 0, indicating a symmetrical concave shape. The effective focal length (EFL) is -150 mm, and the back focal length (BFL) is 148.23 mm.
This lens is suitable for use in a wide range of wavelengths, with a specified wavelength of 546.1 nm. It is a spherical lens, meaning it has a constant curvature throughout its surface. This, combined with its high-quality material and precise manufacturing, ensures excellent optical performance.
