Description
The MediWorks S390L Firefly is a digital slit lamp designed to combine detailed optical examination with high-resolution photography and video of the anterior segment.
Its Galilean microscope provides five selectable magnifications from 6.3× to 40×. The high-sensitivity digital module captures clear slit images under low-light conditions, while its wide dynamic range helps present the iris and sclera simultaneously with balanced color and detail.
The integrated 12-megapixel sensor captures photographs at up to 4056 × 3040 pixels and records 2592 × 1944 video at 30 frames per second. Automatic exposure and preset camera parameters reduce the need for manual adjustments, supporting an efficient examination and documentation workflow.
LED illumination provides up to 150 klx. The optical system includes heat-absorbing, neutral-density, red-free, cobalt-blue and built-in yellow filters. Combining the cobalt-blue and yellow filters improves contrast when documenting corneal fluorescein staining and contact or orthokeratology lens fitting.
When used with the applicable MediWorks software, the system supports patient-image management, comparison and documentation. It can also be upgraded with a compatible dry-eye diagnostic module; this optional module is not included with the standard S390L configuration.
