87-960 50 mm Dia. Germanium Positive Meniscus Lens; EFL=100mm Uncoated
The 87-960 is a 50 mm diameter Germanium positive meniscus lens, characterized by its uncoated surface and an effective focal length (EFL) of 100mm. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.
The lens features a base shape of a circle, with a thickness of 3.8mm at the edge and 5mm at the center. The first radius of curvature (R1) is 107.03, while the second radius (R2) is 160.46. The back focal length (BFL) of this lens is 96.49. The lens is made of Germanium burnett, a material known for its excellent optical properties, particularly in the infrared region of the spectrum.
The lens is designed to operate at a wavelength of 10600nm, making it suitable for various applications in this spectral range. The lens is spherical in shape, a common design for optical components due to its ease of manufacturing and excellent optical performance.
Notably, this lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in higher reflective losses, it can also offer other advantages, such as lower cost, simpler manufacturing, and the ability to customize coatings based on specific application requirements.
