If not properly managed, equipment degradation due to heat can lead to serious accidents. To measure without stopping operations, a "radiation thermometer (thermopile)" is suitable. Unlike contact-type thermometers, it does not touch the object being measured, so heat is not transferred to the sensor, resulting in no thermal degradation of the sensor part, leading to a long lifespan. 【Features】 ■ Measurement without stopping operations ■ Temperature measurement without affecting the subject ■ Quick measurement ■ No thermal degradation of the sensor part, ensuring a long lifespan ■ Hygienic *For more details, please refer to the PDF document or feel free to contact us.

The "radiation thermometer (thermopile)" allows for non-contact temperature measurement. It is hygienic and can improve quality with less concern about foreign substance contamination. Unlike contact thermometers, there is no need to consider temperature changes in the object due to contact, allowing for temperature measurement without affecting the object. Additionally, since it does not touch the object being measured, heat is not transferred to the sensor, preventing thermal degradation of the sensor part, resulting in a long lifespan. 【Features】 ■ Non-contact temperature measurement is possible ■ Hygienic quality improvement is possible with less concern about foreign substance contamination ■ Temperature measurement can be done without affecting the object ■ Measurements can be taken in a short time ■ Long lifespan due to no thermal degradation of the sensor part *For more details, please refer to the PDF document or feel free to contact us.

A certain industrial waste disposal company was considering whether it could sort transparent PP and PE mixed in with the waste after crushing. Therefore, we proposed the use of "SWIRLED," which can utilize the differences in transmittance. As a result, although PP and PE appear the same to the naked eye, using short-wave infrared in addition to visible light has enabled more precise sorting. [Case Study] ■ Issue: Consideration of sorting transparent PP and PE mixed in with waste after crushing ■ Proposal: Use of "SWIRLED," which can utilize differences in transmittance ■ Result: Achieved more precise sorting *For more details, please refer to the PDF document or feel free to contact us.

At a certain company in China, the short lifespan of halogen lamps used in infrared sorting machines was a problem. Therefore, we proposed switching to "SWIRLED," which has a longer lifespan than halogen lamps. As a result, it was common for technicians to spend two days traveling to the site for lamp replacements, but the frequency of replacements dramatically decreased, significantly reducing maintenance costs.

Among infrared rays, those with wavelengths specifically between 1000nm and 2500nm are referred to as "Short-Wave Infrared (SWIR)." Since they have wavelengths close to visible light, optical applications are expected, and common uses include applications such as vein authentication in biometric identification. This document introduces what can be solved using short-wave infrared, as well as actual case studies. We encourage you to read it.

Shortwave infrared (SWIR) LEDs are products that can detect items that cannot be detected by visible light and near-infrared. For example, there are foreign objects such as transparent glass, which passes through visible light and cannot be detected, and stones that are the same color as rice, which can only be detected using SWIR. They can also be used as sorting machines for agricultural products. Additionally, there are wavelengths that indicate water absorption, making it possible to detect water, which is difficult with visible light. They can also be used as water level meters in beverage factories for PET bottles and water tanks. [Examples of Applications] - Detection of foreign objects mixed with grains - Non-destructive measurement of fruit sugar content - Internal measurement of white containers - Measurement of blood components, etc. *For more details, please refer to the PDF document or feel free to contact us.
