Utilizing the differences in transmission rates! Introduction of cases where higher precision sorting has become possible.

A certain industrial waste treatment company was considering whether it could sort transparent PP and PE mixed in with 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 visible light in addition to short-wave infrared 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.

[Second installment!] We have published examples of the use of short-wave infrared LEDs.

  • Product news

Hello, This is Reitron Co., Ltd. We have published actual case studies of the shortwave infrared LEDs we produce. This time, we would like to introduce a slightly different case. There are limitations to the colors visible in visible light, making it impossible to distinguish transparent objects. However, what if we use something other than visible light? We have published a case study that was adopted with that perspective in mind. Please take a look.
