We have published a booklet that includes an integrating sphere with high-reflective white silicone coating instead of barium sulfate, along with standard plates. It is resistant to vibrations, temperature, and water, which expands its range of applications. For more details, please refer to the related links, product page, and catalog page.

Our comprehensive catalog summarizing our products has been updated. - We introduce about 45 different types of light sources. - With comparison charts, the differences between models are immediately clear. - All pages in color. - Products not listed on Ipros are also included. We will give this comprehensive catalog for free to the first 30 applicants! *** How to Apply *** Please fill in your shipping address in the inquiry form and send it.
