Topcon TRC-NW8 Non Mydriatic Fundus Camera
The TRC-NW8 features several automated functions that allow anyone to quickly and easily capture high quality crisp, clear images. Simply align the patient and the instrument automatically focuses and automatically fires.
The TRC-NW8 gives the operator added flexibility in image capture. There are nine flash levels to choose from, and eight peripheral fixation points as well as a built-in standard central fixation point, which provide fixed, reproducible fields for use in various study protocols. These fixation points can be presented in a variety of patterns. A built-in optical green filter provides true optical red free photography which is extremely useful for glaucoma detection.
The TRC-NW8 can be combined with Topcon’s IMAGEnet Lite™ software for efficient data management. IMAGEnet Lite™ features a number of useful utilities including stereo viewing, image manipulation, measurement tools, and an AutoMosaic™ module that allows the operator to automatically merge several images to create a composite view of up to a 100 degree field.
Specifications of the Topcon TRC NW8 Fundus Camera – Non Mydriatic Retinal Camera
True Optical Red Free Photography
Topcon has developed an innovative feature on its Topcon TRC NW8 retinal camera : True optical red free capability with an actual red free filter. This feature allows for high resolution red-free image acquisition that is clearer tahn digitally enhanced images from color-only imaging systems. The red free and color image capabilities are selectable by pulling out the RF filter.
Auto Small Pupil Detection
A common problem are patients with small pupils and when mydriatic drops cannot be used the “Small Pupil” (min.Ø 3.3 mm) option within the Topcon TRC NW8 allows you to still be able to get a shot.
Quality of image is crucial as well as durability
With these important requirements Topcon did not hesitate in deciding on which manufacturer it would use for its digital camera supplier.
Nikon probably has the largest reputation when it comes to digital SLR cameras and is used by most of the worldpress for a very good reason. Therefore you have no need to worry that your new TRC NW8 will ever be compromised by the digital SLR in terms of quality of image and durability.
Lower Flash Intensity
Topcon has always endeavored to keep flash levels as low as possible while at the same time ensuring that good exposed images are achieved. The Topcon TRC NW8 non mydriatic retinal camera is no exception here, but with greater control of the CCD camera, optimum exposure can be achieved each and every time.
In designing the new Topcon TRC NW8 a lot of attention has been spent on the general appearance of the unit with the finest finish and also on the ergonomics. What is clear when you sit down a the camera is how logical everything is and not cluttered by many different cables. The TRC NW8 has a unique way of eliminating connecting cables and gives the operator a clutter free environment.
In line with the requirement for Diabetic screening, when the fixation target mode is set at DFC ( “D” is for centre of optic disc, “C”, is for central macula and “F” is for centre of Fovea), the internal fixation target will move by one in proper position that can be helpful in diagnosis such as glaucoma and diabetes.
Using comprehensive software for capturing, processing, archiving and consulting. IMAGEnet system expands the abilities of the TRC-NW8 into a digital imaging analysis system for clinical application.
Easy alignment, Auto Focus and Autoshoot
Alignment could not be simpler with the new Topcon TRC NW8. Crucially the operator is still in control; however with the very latest in alignment aids the process of getting a sharp focused image time after time could not be easier.
This is a new feature of the Topcon TRC NW8 which allows the operator to choose to have Auto Focus facility. This can be of great healp when trying to photograph difficult subjects or patients with high degree of accommodation. Auto Focus allows for a sharp image every time.
The Topcon TRC NW8 has the option for Auto Shoot which is of great benefit to the operator as it monitors when all parameters are correct and takes the picture. This rapidly speeds up capture process and is of great benefit when photographing patients who have problems fixating.
