The SL-D701 is a digital slit lamp which can be used with conventional halogen illumination or with LED illumination. LED illumination ensures consistent colour temperature during light intensity adjustment and easier visualization of details in the anterior chamber and vitreous such as flare and inflammation.
The SL-D701, digital slit lamp, incorporates four filters for enhanced examination:
- cobalt filter
- red-free filter
- ND filter
- amber filter
The amber filter improves the contrast and colour of retinal observation. The SL-D701 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.
SL-D701 Blue Free Filter™
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-D701 will seamless integrate with:
- 5 megapixel camera
- BG-5, background illumination / meibography system
- Topcon Fundus Viewer FV-1L.
The SL-D701, 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.
BG-5 background illumination
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.
