This auto ref-keratometer is professionally engineered to deliver reliable and high-precision performance. The improved technology makes the measurement accurate and stable. It comes with a robust housing for a long service life. 	 New design. 	 Nice color combination. 	 Professional and fashionable. 	 Supports various measurements. 	 Not only the usual refractometry and keratometry, but also the corneal diameter and base curve of the contact lens can be measured with this instrument. 	 It can also measure PD and pupil sizes. 	 Wide dioptric measurement range. 	 It covers a wide measurement range, from -20D to +20D, even an examinee with strong myopia can be measured. 	 As measuring the curvature, it can measure by 2.0mm of least pupil radius. 	 More accurate measurement and multi-measurement ways. 	 The foggy method of the eye fixation target makes the eyes of examinee comfortable and enables to get more accurate measurement data. 	 Both automatic measurement and manual measurement are available. 	 It is easy for examinee to measure.

This is a photometric detector with a sleek and elegant look. It is well engineered to work with high stability and reliability. This photometric detector offers an extra-long service life. 	 Photometry is the science of the measuring visible light, in terms of its perceived brightness to the human eye. 	 The photometric detectors are built by using selected, stability tested Si-photovoltaic cells with advanced color filters. 	 They are designed to simulate the response of the human visual system and match to the spectrum of CIE V(&lambda;) function. 	 The error function f1&rsquo; is an index that indicates the degree of spectral mismatch. 	 We provide different products in three error classes, such as class A, class B and class C. 	 Every type detector is individually calibrated and measured f1&rsquo; to conform to the CIE specifications. 	 They are available to be used to measure illuminance (lx) and luminous flux (lm). 	 Class A with f1&prime; &lt; 1.5%. 	 Class B with f1&#39; &lt; 3%. 	 Class C with f1&#39; &le; 3.75%.
