optical coherence tomography device Class I Continuous Operation Medical Electrical Equipment
The design of the Retiview 500 complies with the EMC standard IEC 60601-1-2 for medical electrical equipment. The installation and use of the device must comply with the following EMC statement.
Optical Coherence Tomography Machine (OCT) USES frequency domain optical coherence tomography (SD-OCT) to obtain three-dimensional tomography images of the posterior segment of the eye. Sd-oct is based on low-coherent optical interferometry. In SD-OCT, light from a low-coherence source is divided by the interferometer into a sampling path (into the eye) and a reference path. The beam returning from both paths passes through the interferometer and mixes to the spectrometer. The spectrometer detects the mixed spectrum of all frequencies at the same time, and the Fourier transform of this spectrum can be used to obtain the intensity of the light signal backscattered at different depths. Since different tissues have different backscattering rates, the optical signal contains the structural information of retinal tissues. The 3d tomographic images of the retina can be obtained by transverse scanning and reconstruction of the acquired signals.

Compact Design
Features:
1. Compact Design: Everything is inside this compact body. No external computer is needed. Plug in the power cable, then you are ready to go.
2. PC Inside: Data acquisition and processing are accomplished by the internal computer. The data can be transported via ethernet or external harddrive. Peripheral devices, such as keyboard or printer, can be connected to the computer ports.
3. Easy Installation:No complex connection or setup. Compact body can fit in even small space.
Optical Coherence Tomography Machine has never been so affordable. More people can benefit from the advanced technology now.
The Retiview 500 uses RF frequency energy only for its internal functions. Therefore.its RF emissions are very low and are not likely to cause any interference in nearby electronic equipment.
