Slit lamps SL 990
20% increase in optical resolution and contrast
20% increase in light transmission
The SL 990 series is characterized by a modern optic project and uses a multilayered antireflection treatment that ensures a more effective transmission of light, thus improving the optic resolution and contrast by 20%.
The optic quality of the SL 990 series moreover provides a 20% increase in optic transmission and a 10% enlargement of depth of field.
Illumination
The 6V 20W halogen bulb assures high quality color temperature. Thanks to the tilting device, the inclined light can be vertically projected up to 20° with 5° intervals.
This shows to be very helpful in the horizontal optical observation, gonioscopy and posterior eye examination.
Microscopio Zoom microscope
Continous enlargements from 6x to 33x, giving clear, brilliant and well contrasted images thanks to the multilayered antireflection treatment. All the accessories of the Galileian microscope can be used.
System for inserting yellow filters for fluoresceinic test
The CSO slit lamps on Galileian microscopes with 3 and 5enlargements and Zoom microscopes allow the option of having the yellow filters (fluoresceinic test) directly inserted into the microscope box for faster testing and improved optic yield of the set.
Beam splitter
System for optic splitting of the microscope image (50% on videocamera - 50% on operator’s eye).
It can be supplied in the following models:
- single plug for Panasonic microcameras
- single plug for C gauge telecameras
- single plug (requires adaptor/joint for telecameras)
- double plug
They are also easy to install on Galileian and Zoom microscopes (see illustration).
