Both X-line and A-line lenses are appropriate for laser scanning image quality. The Olympus X-line lenses provide high quality chromatic aberration correction from 400-1000 nm resulting in exceptional color reproducibility. Additionally, the high numerical aperture enables acquisition of high-resolution, bright images and good edge correction (flatness) facilitates high quality images with greater uniformity from the center to the edge, even with a large field of view.
A-line lenses are also great for super resolution and are an important choice to consider for your specific application. For instance, the A-line silicon oil immersion lenses are recommended for live cell applications as silicon oil does not dry at 37˚C and its RI remains constant. Moreover, silicone oil lenses offer a long working distance to enable observation at deeper tissue level and across broader fields. Specifically, the Olympus A-line silicone lens 30x is ideal for organoid and zebrafish imaging.
