Simple Design + Simple Operation
The design was inspired from the shape of firefly. The smart design largely saves space for doctors compared with built-out camera.
We have preset many camera setups so the user does not need to set many parameters before using the device.
The user can operate the machine directly once the installation has been finished.
The device carries following automatic functions for photo shooting and processing when equipped with our MediView software:

Auto Focus/ISO
Auto Exposure
Auto White Balance
Right/Left Eye indicator
Auto Focusing Calibration

Adjustable Aperture

The aperture can be adjusted at 6 different levels
to meet different view of depth and brightness

HDMI output

The HDMI output can be used to connect the S390H/S390L slit lamp with monitor.
The doctors can share the live eye examination status simultaneously
with patient’s family members or students for teaching purpose.

Easier Installation

Our compact control panel with built-in power supply makes it
much easier to install the slit lamp especially when installing the slit
lamp on a ophthalmic unit. The users do not need to find place to
install the chunky power box.
Quick Capture Button

There is a quick button on the control panel that enables doctors
to shoot photos conveniently . Once they observe the suitable
photo to describe pathology, just press the capture button and
the photo will be recorded.

Coaxial Illuminator

The new LED illuminator is positioned coaxially to the microscope.
It provides an adjustable circular beam of light to enhance the
digital capturing effect.

Less Cables with Extra USB Port

When applying the new control panel, there will be less cables
exposed outside. Extra USB port is provided to charge other
medical device.
