Shining a new light on slit lamp imaging

Topcon’s latest slit lamp, the SL-D701, provides bright and clear LED illumination and it is ready for digital interface with the ‘DC-4’ photo attachment and the ‘BG-5’ LED background illumination system. 

The short wavelength of light emitted from the LED is said by the company to provide greater comfort for patients and superior clarity for imaging and observation. It also enables easier visualisation of structures such as the endothelium and cells within the anterior chamber.

The ‘DC-4’ Digital Photo Attachment has a specialised, high resolution imaging chip which is capable of capturing full colour still imaging, video and infrared light for meibography.

The ‘BG-5’ background illumination system provides extra light via an additional extra bright LED, which enables imaging of slit beams combined with diffuse light, viewed as a very useful clinical feature. It also contains the infrared LEDs for meibomian gland illumination.

The fluorescein version comes with an all new wavelength matched excitation and a barrier filter system, which can produce imaging which is up to eight times brighter than pervious digital imaging systems. 

Both versions of the ‘SL-D701’ come with a neutral density filter, which increases visualisation and imaging in gonioscopy, an amber filter for posterior visualisation and the red-free filter, which benefits anterior blood cell motion recording. 

With all of the features, including a magnification of up to 40 times, the ‘SL-D701,’ combined with the ‘DC-4’ is viewed by the company to be “the most versatile slit lamp imaging system” in the Topcon portfolio.
