I would start by checking with Nikon but if they can't help, for
colored-glass filters, try Schott:
http://www.schott.com/advanced_optics/english/our_products/filters/index.html

However, a 20 nm bandpass filter doesn't sound like a colored-glass
filter--it will probably need to be an interference filter.  Those can
be obtained from companies like Omega Optical, Chromatechnology, and
Semrock.

Good luck!
