S290 Slit Lamp Microscope
S290 Slit Lamp Microscope
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
Auto Exposure
Auto Gain
Auto White Balance
Auto OD/OS Indicator
High Sensitivity Wide Dynamic Range
The slit is still clear and sharp under weak light. Iris and sclera images are simultaneously clearly presented with
more realistic and evenly distributed color.
Lens Orthokeratology Lens Fitting
HD Optical System
Optical resolution is up to 2700·N lp/mm （200 lp/mm）, providing more details of the pathologies.
LED Illumination
The light of MediWorks LED lamp is very similar to halogen lamp, which conforms to the operating habit of doctors. The LED lamp MediWorks applied has a low color temperature and high illumination intensity, making view of retina without glare-colors much more vivid and view of cornea with nerves pop out better. The LED lamp has a longer life span and consumes less energy.
Built-in Yellow Filter
Increase positive rate of early corneal epithelial staining Built-in yellow filter along with cobalt-blue filter increases the contrast of Sodium Fluorescein Staining image.
Software Features
Convenient Patient Management
The patient management system enables clinicians to build and edit patient record,search information by inputting keywords.Clinicians can easily record symptoms and manage the data all the time. The software supports DICOM which makes the images captured by Firefly be easily integrated into hospital’s medical system.
Functional Image Analysis
Clinicians can measure the pathology area with our powerful software tools and change the contrast and brightness of the images. Clinicians can also compare several images at one time to analyze the symptoms and pathology.
Orthokeratology Lens Fitting Assistance
The optometrists can capture and record high resolution fluorescein images of lens fitting and real-time video without a recording time limit. By comparing the different lens fitting effects, the optometrist can show and educate patients which lens is most suitable for them.
Customized Auto Exposure Value Setting
Clinicians can customize auto exposure values according to the image demand and save as templates for future capturing purpose.
Also, the printing report can be customized according to clinician’s needs.
Tear Film Breakup Time
High-performance digital module, doctors can get the tear film Breakup time and judge the stability of it by high-resolution video recording.
Red Eyes Analysis and Keratopathy Exposure
With a built-in yellow filter, doctors can accurately analyze eye surface damage and inflammation images.
Tear Meniscus Height
Doctors can obtain tear meniscus height by using measuring function in the Mediview software, and effectively evaluate tear
meniscus height.
Optional Accessories
Metal Plate (work with refraction units)
When placing a slit lamp on a refraction unit, it is suggested to use MediWorks metal plate for easier installation. With smart size design, it is easy to move the whole suite of slit lamp from one refraction unit to another without drilling any screw holes on the table tops.
Instrument Stand Pin (work with US style instrument stand)
This instrument stand pin is specially designed to install MediWorks slit lamps onto US style instrument stands. The diameter of the joint pin is 19mm, compatible with most of the instrument stands. With this pin the slit lamp table top can be installed to the lower slit lamp arm of instrument stand.
Measuring Eyepiece
Equipped with a reticle inside, the eyepiece has a measuring function which can facilitate doctors to measure the pathologies conveniently and give more accurate diagnosis.
Observation Tube
Connected through beam splitter, the observation tube enable another medical staff to observe the patient’s eye condition from the slit lamp. It is good for teaching education purpose.
