III. FAQ about Linshang Window Film Transmission Meter

  1. 1. What is the difference between 940nm and 1400nm instruments?

    The two bands of 940nm and 1400nm are relatively representative bands. Most of the absorption films (heat-absorbing films) have better infrared blocking effect at 940nm, while the magnetron sputtering reflection film has better blocking effect at 1400nm such as metal film and ceramic nano film. Please choose the right instrument for your own film category.

  2. 2. What is the difference between a metal film and an endothermic film?

    The metal film is produced by a magnetron sputtering process. A large amount of metal elements are added and the has a good reflection ability to the infrared film. It is insulated by the principle of reflecting infrared rays.

    The absorption film is added with an infrared absorber during production and the infrared is absorbed by the film. It is insulated by the absorption principle and secondary heat radiation will be generated after the heat absorption is saturated.

  3. 3. Can 940nm instrument measure metal film? Can the 1400nm instrument measure endothermic films? When the same film is tested by both 940nm and 1400nm, what is the difference in infrared rejection rate?

    Each film tested by both 940nm and 1400nm instruments will have infrared blocking rate data. Due to different production processes, the thermal insulation data of some films at 940nm will be larger than the thermal insulation data of 1400nm. Some films will have larger thermal insulation data at 1400nm.

    E.g: Vickers V70 has an official infrared rejection rate of 98%. The measurement data tested by 1400nm instrument is about 98%, while the measurement data tested by 940nm instrument is only about 88%.

    The 3M Jingrui 70 has an official infrared rejection rate of 98%. The measurement data tested by 940nm instrument is about 99%, while the measurement data tested by 1400nm instrument is only about 87%.

    There are too many types of films and the data differences between 940nm and 1400nm are also very different. Some films may not differ much and some films differ by 30-40%, so we can't tell you the exact value.

  4. 4. Why are 1400nm instruments so much more expensive than 940nm instruments?

    It's all about the cost of raw materials. The cost of a 1400nm light source and receiver is much higher.

  5. 5. Can the window film transmission meter measure the insulation rate?

    Our instrument measures the infrared rejection rate. The higher the infrared rejection rate, the higher the thermal insulation rate. Because visible light also has a small amount of heat, in the strict sense, the heat insulation rate needs to integrate visible light, infrared and ultraviolet heat insulation data. Ultraviolet heat is very small and visible light is beneficial. Therefore, infrared is the main source of heat, so the infrared rejection rate is basically equivalent to the thermal insulation rate.

  6. 6. What is the difference between LS300 and LS301?

    The LS300 measures the real-time temperature (degrees Celsius) and the temperature difference. The LS301 has an additional function to measure the infrared rejection rate of 940nm than the LS300. At the same time, the LS301 also measures the real-time temperature value. 

  7. 7. What is the difference between the new and old LS101?

    The parameters of the new and old models are basically the same, both of which can measure three parameters of heat insulation, UV rejection and light transmission.

    The old model can only be used when plugged in. It is a digital tube display. The new model is an LCD display. It uses 4 AA batteries and has a USB interface on the instrument. It can be directly powered by a power bank or 5V charging head.

    The light source of the old LS101 is a point light source, which is only suitable for films and thin glass; the new LS101 uses a parallel light path design and thick glass can also be tested.

  8. 8.Are you a manufacturer or trade company?

    We are factory , we have engineers for researching & designing  and workers for produce and operate etc, we could support you one-stop products and service.

  9. 9.Do you offer OEM and ODM service?

    Yes. We can supply OEM and make customized design for any specific application.
