PAC12AR.16 25 mm Dia. N-LAK22/N-SF6 Plano-Convex Achromatic Doublet; EFL=100mm NIR-IR 750-1550nm
The PAC12AR.16 is a high-quality achromatic doublet lens, designed and manufactured by MKS/Newport, a leading vendor in the optical industry. This lens, with a catalog number PAC12AR.16, is specifically designed for use in the near-infrared and infrared spectrum, between 750nm and 1550nm.
The lens features a circular geometry with a diameter of 25mm, making it suitable for a wide range of optical applications. The lens has a plano-convex design, meaning one side is flat, and the other side is curved, with a radius of curvature of 57.01mm. This design helps to minimize spherical aberration and distortion, ensuring high-quality imaging.
The lens is made from two different materials, N-LAK22 and N-SF6, both from Schott, a renowned manufacturer of optical glass. These materials have been carefully selected to create an achromatic doublet, which corrects for chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points.
The lens has an effective focal length (EFL) of 100mm, providing a moderate magnification. The edge thickness of the lens is 8.49mm, and the center thickness is 10mm, providing a robust and durable structure. The lens is coated with New AR-16e on both the front and back surfaces, reducing reflection and increasing transmission in the NIR-IR spectrum.
