Optical resolution increased by 40% Built-in yellow filter The Meibomian glands examination

ophthalmic slit lamp

Simple Design + Simple Operation

The design was inspired from the shape of firefly. The smart design largely saves space for clinicians compared 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
