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%.
