Takagi 700GL NSW Slit Lamp Microscopes
The principle of NSW
When observing the fundus with a slit lamp microscope, the range obtained by the binocular vision is only the part where the right and left visual fields are overlapped (Stereoscopic Vision Area). This is because the larger the viewing angle becomes, the narrower the range obtained by binocular vision becomes.
By making this viewing angle at 4.1 degree, the area where the left and right visual fields overlap is increased, and the range obtained by binocular vision becomes wider.
The difference between 700GL and 700GL NSW
700GL’s viewing angle is set at 10 degree. In comparison with competitors slit lamps, 700GL offers a better view of the fundus and it is an excellent slit lamp microscope for general examination.
When NSW is turned ON, the viewing angle is set at 4.1 degree, which gives approximately 133% of the fundus view that 700GL offers. Therefore, it is a perfect slit lamp for doctors who frequently examine the retina of outpatients.
*700GL NSW is a factory option specification. Standard 700GL cannot modified/converted to 700GL NSW.
