67-436 2.5mm Dia. x 3.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-436 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 2.5mm and a focal length of 3.0mm, making it a compact and efficient optical component. The lens is made from the material n-lasf9 schott, a detail that could be crucial for users looking for specific material properties.
The lens features a front and back coating of edm nir-ii std curve, which is particularly noteworthy as it enhances the lens' performance in the near-infrared spectrum, specifically between 750-1550nm. This coating is part of the NIR II series, which is known for its high transmission and low autofluorescence, making it ideal for applications such as biomedical imaging, night vision, and spectral analysis.
The lens has a thickness of 0.47mm at the edge and 0.8mm at the center, providing a balance between compactness and durability. The inner and outer radii are 0, indicating a flat surface on one side and a curved surface on the other. The effective focal length (EFL) is 3mm, and the back focal length (BFL) is 2.57mm, both of which are essential specifications for lens selection and system design.
