The objective lens adopts apochromatic double separation optical structure, the two-piece apochromatic lens has better compatibility with the adhesive lens, and the imaging clarity is high. There is no need to worry about the photosensitive adhesive aging in the large-caliber objective lens, which may lead to yellowing and edge peeling over time. The objective lenses are tested and paired with parallel light tubes and dividers to ensure that each set of objectives provides consistent imaging performance. The high resolution, low dispersion objective is the best choice for various applications such as telescope objectives and parallel optical pipeline production test instruments.
