B+W filter

[miniUltraman]

I have 3 x B+W 77mm MRC F-Pro UV Haze filters. I look at it under white florescent light. All three give me a different reflection.
a) deep purple
b) light green
c) lighter green. Almost white

I compared all 3 have the same print as in 77mm MRC UV Haze... and the sides with "F-Pro" and "Made in Germany"... Is it normal that they have different coatings?
(Sorry, it might sound like a stupid question... just wonder why they are different :dunno

Perhaps batch variation. You didn't buy all at the same time did you?

This might be the only reason I can convince myself... Yes, they are bought at different time. Definitely no access cleaning for me as all of them are pretty new and low usage... Just wondering if anyone with multiple filters have encountered this :sweat:
