Where can I find a spec sheet for this Raspberry Pi HQ camera microscope lens?

There’s this microscope lens listed on the seeed studio website under SKU 114992279. The other lens options listed on the page seem to have specs listed, but I can’t find anything for the microscope lens. Any ideas?

I find a spec for you.

Thank you @jiachenglu. Do you know if there’s an English version?

Here is the English version I translate just now.
