This is a Plano-Convex lens, a type of spherical lens with a flat surface and a curved surface, offering a variety of advantages in optical systems. The lens has a diameter of 12.5 mm and is mounted on UVFS, a material known for its excellent optical properties.
The lens features an effective focal length (EFL) of 20mm, making it suitable for applications that require a longer focal length. The EFL is a critical parameter in lens selection as it directly influences the size and magnification of the image produced.
The lens is designed to operate within the wavelength range of 725-1050nm, which includes near-infrared and some portions of the visible spectrum. This makes it suitable for applications such as night vision, thermal imaging, and other systems that operate in the infrared region.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. Coatings are applied to lenses to enhance their performance by reducing reflections, increasing transmission, and protecting the lens surface. This particular coating is designed to provide broadband anti-reflection properties, ensuring high transmission across the entire operational wavelength range.
