Difference between LS110A and LS110H Split Transmission Meter

The infrared peak wavelength of LS110H Split Transmission Meter is 1400nm,and the infrared peak wavelength of LS110A Split Transmission Meter is 950nm. Linshang Technology combined with the feedback from customers and our experience during the past decade, come to a conclusion: most of the absorption film will have higher Infrared rejection rate when they are measured with 950nm infrared light source , but the metal film is the opposite,it will have higher Infrared rejection rate when they are measured with 140nm infrared light source.
       A few days ago a customer bring some samples to our company, they want to measure them with both LS110A and LS110H Split Transmission Meter, after comparison, they finally selected  the LS110A Split Transmission Meter for their absorption films.
       So what is the difference between two split transmission meters?
       The difference between LS110A and LS110H Split Transmission Meter is the infrared wavebands. The infrared peak wavelength of LS110H Split Transmission Meter is 1400nm,and the infrared peak wavelength of LS110A Split Transmission Meter is 950nm. Linshang Technology  combined with the feedback from customers and our experience during the past decade, come to a conclusion: most of the absorption film will have higher Infrared rejection rate when they are measured with 950nm infrared light source , but the metal film is the opposite,it will have higher Infrared rejection rate when they are measured with 140nm infrared light source. 

As shown above, LS110A Split Transmission Meter and LS110H Split Transmission Meter were measuring the same film , because of the different infrared light source of two instruments , the infrared rejection rate will also be different, but the difference depends on the physical characteristics of the sample itself.
       Linshang Technology can provide customers with sample measurement services, you can send your samples to our company, and we use different instruments to test and then feedback the results to you, you can select the most suitable instrument according to the results.
