SL-D7 - slit lamps
The SL-D7 is a digital slit lamp which can be used with conventional halogen illumination or with LED illumination. The LED illumination allows observation under a brighter, homogeneous condition than the conventional halogen illumination. LED illumination ensures consistent colour temperature during light intensity adjustment and due to a shorter LED wavelength easier visualization of details in the anterior chamber and vitreous such as flare and inflammation.
• Five magnifications 6x, 10, 16x, 25x, and 40x for daily specialist use
• Halogen and LED illumination source available
• Four filters for enhanced examination
• Blue Free Filter™ system for 1.6x brighter fluorescein observation
• Oblique illumination prevents reflection
• Optimal clarity, colour resolution and depth-of-field
• BG-5 provides IR illumination which enables observation of Meibomian glands
• BG-5 adapts to Topcon slit lamp SL-D701
• BG-5 provides shadow free observation
The SL-D7, digital slit lamp, incorporates four filters which can be selected:
- cobalt filter
- red-free filter
- ND filter
- amber filter
The amber filter improves the contrast and colour of retinal observation. The SL-D7 has 12,5 x eyepieces and converging binocular tubes with a parallel magnification body (6x, 10x, 16x, 25x and 40x) for extremely sharp stereoscopic observation. As standalone the joystick trigger button of the SL-D701 provides an illumination boost for detailed observation, available for halogen illumination and LED illumination.
The SL-D701 Blue Free Filter™ exists of a combination of the special exciter filter and barrier filter (factory option). This Blue Free Filter™ system ensures a 1.6 x brighter fluorescein observation than the cobalt filter. Tear flow details and scars can be clearly viewed with less glare or pooling.
The slit lamp corporates a cable management system if used as a digital slit lamp. The SL-D7 will seamless integrate with:
- DC-4
- 5 megapixel camera
- BG-5, background illumination / meibography system
- Topcon Fundus Viewer FV-1L.
The SL-D7, digital slit lamp, has options such as a yellow filter diaphragm filter to increase field-of-depth, tonometer mount, parallel binocular tubes, assistant observation tube and various relay lenses.
The Topcon BG-5 background illumination consist of a white LED source. The background illumination is required to use for overview images with low magnification and will provide a shadow free observation with natural colours. For the background illumination two apertures are available which results in a high and low brightness. The BG-5 also provides infra-red illumination that illuminates the Meibomian glands to assess its integrity. The observed images can be displayed on a computer screen and digitally captured with the Topcon digital slit lamp camera DC-4 and archived for teaching and documentation. The BG-5 can be mounted on Topcon slit lamp model SL-D701 exclusively.
