The 84-229 is a Plano-Convex Spherical Lens, designed and manufactured by Edmund Optics, a leading provider of optical components. This lens boasts a 9.0mm diameter and a 90.0mm focal length, making it suitable for a wide range of applications.
The lens is crafted from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures that the lens delivers sharp, clear images with minimal distortion.
The lens features a Laser V-Coat 1550nm coating on both the front and back surfaces. This coating enhances the lens's performance in the 1550nm wavelength range, improving its transmission and reducing reflections. The coating also provides excellent environmental resistance, ensuring the lens maintains its performance even in challenging conditions.
The lens has a thickness of 1.78mm at the edge and 2.0mm at the center, providing a robust and durable design. The inner and outer radii are 0mm, indicating a flat surface on the incident side and a curved surface on the exit side. The effective focal length (EFL) is 90mm, and the back focal length (BFL) is 88.68mm.
