SK-850A projection perimeter is a latest humphrey visual field analyzer which could be one of leader all over the world. It is designed full compliance with the Goldman standards; All the wavelengths, luminance and stimulus size are designed according to International standard, and the analysis software includes various factors which may affect the visual field during the checking. This perimeter can satisfy the clinical requirements of top Medical Institution and specific requirement of Scientific Research Institution.

Projection Spot Compliance With the International Standardand Calibrated Initial Luminance Brightness
1.SK-850A adopts optical gradual coating technology to obtain international standard luminance brightness 0~10000asb(0- 51db) by precisely controlling the optical lens transmittance, ensuring that the brightness of each dots are full compliance with the International standard.
2.With power up system, perimeter software will get the digital calibrated array mode of optical gradual lens and coated lens by actinoscope on the optical projection head, to make sure the initial projection brightness standard won’t be changed by unstable Environmental voltage and bulb decay, It can ensure that all the medical measured data is under the international standard brightness which is accurate.

Excellent Test Strategy Designed
The designed test strategy will shorten testing duration and improve the accuracy of result, which considers the greatest possibility of different age range, responsiveness, visual field loss, and distribution regularities of vision island.
