Simple Design + Simple Operation
The design of the ophthalmic slit lamp S390L(Firefly WDR) was inspired by the shape of the firefly. The smart design largely saves space for clinicians compared to other bulky camera systems. We have preset many camera parameters so the user does not need to adjust settings before using the device. The user can operate the machine immediately once the installation has been finished. The device has the following automatic functions for photo shooting and processing when equipped with our Mediview software:
- Wide Dynamic Range
- Meibomian Glands Examination
- Auto Exposure
- Auto Gain
- Auto White Balance
- Auto OS/OD Indicator
General description
The S390H&S390L slit lamps series is slit lamps including motorized focusing digital module.
S390H&S390L slit lamps can only compatible with motorized focusing digital module. Working principle: A beam of light attached to the slit lamp projects to the patients' eye, which forms an optical section of the living tissue of the eye, in this way the doctor can finish the observation and examination. Slit Lamp Microscopes are used to observe the disease of the anterior structures and tissue damage of eyes.
Instruments classification:
This instrument is categorized to Class I Type B according to IEC 60601-1 standard, which cannot be used under two circumstances: a flammable anesthetic gas and air mixture, oxygen or nitrous oxide gas and air mixture. This instrument can be running continuously. It doesn't belong to category AP or APG.
Indications for use:
The S390H&S390L Slit Lamps are AC-powered slit lamp biomicroscopies intended for use in eye examination of the anterior eye segment, from the cornea epithelium to the posterior capsule. They are used to aid in the diagnosis of diseases or trauma which affects the structural properties of the anterior eye segment.
