32-994 25mm Dia. x -100mm FL; Uncoated; Double-Concave Lens
The 32-994 is a spherical lens with a base shape of circle, sourced from the reputable vendor, Edmund Optics. This lens falls under the category of Spherical Lens (Concave-Concave) and is designed for use in optical systems that require concave-concave lenses.
The lens has a diameter of 25mm and a thickness at the edge of 6.43mm, while the thickness at the center is 5mm. The effective focal length (EFL) of this lens is -100mm, making it a double-concave lens. The first radius of curvature (R1) is -104.2mm, and the second radius of curvature (R2) is 104.2mm. The back focal length (BFL) of this lens is -101.64mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is uncoated, which means it does not have any anti-reflective coating. This may result in higher reflective losses, but it also means that the lens is less susceptible to damage from environmental factors.
The lens is designed to operate at a wavelength of 587.6nm. This wavelength falls within the visible light spectrum, making this lens suitable for use in applications that involve visible light.
