    QUESTION: Is AL-6261 the same as OKP4?

     

    ANSWER:

    Yes.  We re-label the OKP materials under the ÅngströmLink (AL) label, where the last two digits of the product name indicate the refractive index:

    askfocchartokp

    If you get a 25kg bag of any OKP product it will arrive in the original Osaka Gas packaging and you will see the original Japanese labeling on the bag. If you purchase a 5kg bag it will arrive in a sealed metalized bag (which I repackage myself for quality control purposes) and you will have to trust us.  In this case we are happy to provide the original Osaka Gas lot number on the COC.
