Motorized focus digital slit lamp microscope S390L

The product design is inspired by the shape of fireflies. Compared with the traditional external digital camera slit lamp, the compact appearance greatly saves space. The doctor can collect and record perfect anterior segment images in real time without setting the camera parameters before use.

This equipment has meibomian gland inspection, wide dynamic range, high sensitivity, automatic exposure, automatic white balance, and automatic identification of left and right eyes during the process of shooting and processing pictures.

Product Advantages

✦ High-definition optical system

The optical resolution reaches 2700·N line pairs/mm (200 line pairs/mm), and the details of the lesion are clearer.


✦ Built-in yellow filter

Built-in yellow color filter, with cobalt blue light illumination, increase the contrast of corneal fluorescein sodium stained image. Effectively improve the positive detection rate of early corneal epithelial spot staining.


✦ Meibomian gland examination


✦ Convenient information management system

The case management system enables doctors to create and edit case files, and query cases by entering keywords. The doctor can quickly record the patient's disease in the software. The system supports the DICOM protocol, so that the images collected by Firefly can be easily connected with the hospital's medical system.


✦ Multifunctional picture editing function

Doctors can use the editing tools in the software to measure the lesion area and adjust the brightness and contrast of the photo. At the same time, doctors can compare multiple patient pictures to analyze lesions and disease cases.


✦ Assist in fitting of orthokeratology lens

Doctors can collect high-definition corneal fluorescein staining photos and videos (without recording time limit) and support multi-image comparison. Doctors can fully record the process of each lens deployment for communication and follow-up review.


✦ Smart exposure value setting

The doctor can choose the automatic exposure mode, or customize the exposure value, and save the parameters as a template for acquiring images later. The printed report can also be customized according to the needs of the doctor.


✦ Meibomian gland examination

With the built-in infrared light source, the doctor can more accurately judge the missing state of the meibomian glands.


✦ Time to tear film rupture

With the high-performance digital module, doctors can obtain the tear film rupture time through high-definition video, and effectively judge the stability of the tear film.


✦ Jealous analysis and corneal staining

With a built-in yellow filter, doctors can obtain more accurate images of ocular surface damage and inflammation.


✦ The height of the river of tears

Doctors can obtain the height of the tear river through the measurement function of the Mediview image management software, and effectively evaluate the tear secretion.
