IR rransmission of ZWO RGB filters

esordini

Dear tech support.
I am planning on buying a 1.25" ZWO LRGB filter set such as this one:

https://astronomy-imaging-camera.com/product/zwo-new-rgbl-filters-optimised-asi1600

or maybe the old, non CMOS-optimized version. I would need just the three RGB filters which I plan on using for planetary imaging with a ZWO B/W camera, Since IR blocking is very important for planetary imaging, my question is: can these filters be used without an IR-cut filter? I.e. do they natively block IR?

Thank you in advance

Yes, You may refer to this transmission curve of the filters, R G B filters will block IR and UV.

@Tech@ZWO#59431 Hello, thank for your reply. What about the "old" filters (I mean, the ones not optimized for use with the ASI1600)?

Thanks
