Received ZWO Filter Marked Only ‘IR Cut’ – Is It UV/IR?

aristo

I ordered the ZWO 2-inch UV/IR Cut-Off filter from your authorized dealer, COSMOS.
Today I received the filter, but the label on the box only states “IR Cut-Off” — there is no mention of UV. Additionally, there is no transmission spectrum diagram included, as is commonly provided by companies like Optolong.
I contacted the dealer, and they replied that the filter is indeed a UV/IR Cut-Off filter, even though it is not clearly marked as such on the packaging or the filter itself.
I would appreciate your confirmation:
1. Is this filter indeed both UV and IR Cut-Off?
2. If so, why is this not specified on the filter or included in any accompanying documentation?
Thank you in advance for your clarification.
Best regards,
Ari

Tech@ZWO Thank you for your reply.
I recommend that ZWO consider clearly marking “UV/IR Cut-Off Filter” on the filter’s thread ring to avoid confusion for customers, as this is commonly done by other manufacturers.
