87-967 25 mm Dia. Germanium Positive Meniscus Lens; EFL=25mm BBAR 8-12µm
This is a 25 mm diameter Germanium positive meniscus lens, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts an effective focal length (EFL) of 25mm and is coated with BBAR 8-12µm on both the front and back surfaces.
The lens geometry is characterized by a thickness of 1.3mm at the edge and 2.5mm at the center. The first radius of curvature (R1) is 28.32mm, while the second radius (R2) is 42.46mm. The back focal length (BFL) is 23.34mm. The lens is spherical in shape and has a base shape of a circle.
The lens is made of Germanium burnett material, which is known for its excellent optical properties, particularly in the infrared region of the spectrum. The BBAR 8-12µm coating enhances the lens' performance by reducing surface reflections and increasing transmission in the specified wavelength range.
