The 88-169 is a Plano-Convex (PCX) lens with a diameter of 50mm and a focal length of 150mm, making it suitable for a wide range of optical applications. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made of Calcium Fluoride (CaF2), a material with a high refractive index and low dispersion, making it ideal for use in applications that require high precision and minimal chromatic aberration. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this also means that it may be more susceptible to environmental factors such as dust and moisture.
The geometry of the lens includes an edge thickness of 2.33mm and a center thickness of 7mm. The effective focal length (EFL) is 150mm, and the radius of curvature (R1) is 69.31mm. The back focal length (BFL) is 145.21mm, and both the inner and outer radii are 0mm.
This lens is designed to work with a wavelength of 266nm, and it is spherical in shape. The material ID for this lens is "caf2 mal-1963". According to the vendor's website, this lens is currently in stock, making it readily available for immediate use.
