87-962 25 mm Dia. Germanium Positive Meniscus Lens; EFL=30mm BBAR 3-5µm
This is a 25 mm diameter Germanium positive meniscus lens, sourced from the reputable vendor, Edmund Optics. The lens boasts an effective focal length (EFL) of 30mm and is coated with BBAR 3-5µm on both the front and back surfaces.
The lens geometry is characterized by a thickness of 1.5mm at the edge and 2.5mm at the center. The front and back radii of curvature are 33.38mm and 50.04mm respectively, while the back focal length (BFL) is 28.31mm. The lens is spherical in shape and has no inner or outer radius specified.
The lens is made of Germanium burnett material and is designed to operate at a wavelength of 10600nm. The BBAR coating on both surfaces enhances the lens' performance by reducing reflection and increasing transmission.
This lens is a versatile optical component, suitable for a wide range of applications. Its positive meniscus design and high-quality coating make it an excellent choice for applications that require high transmission and low reflection.
