## Description



## Features

- Model:50mm, Diameter:51mm, Focus:360, Focusratio:F7.2, Film:Blue
- The objective lenses are all equipped with apochromatic double-separation optical structure, and the two-piece apochromatic lenses have better compatibility with the bonded ones, resulting in high imaging sharpness with no worry about the aging of the photosensitive glue in the large-diameter objective lenses that may cause yellowing and edge peeling over time.
- The objective lenses are tested and paired for imaging quality through a parallel light pipeline and dividing plate, ensuring that each set of objective lenses delivers consistent imaging performance.
- High-resolution, low-dispersion objective lenses are the best choice for various applications such as telescope objective lenses and parallel light pipeline production testing instruments.
