red lens filter material.

[Instrument Resources of America]

Hi all,

    I am in need of a small piece of the 'red lens filter material'
that was quite often placed in front of Nixie tubes in test equipment.
Does anyone know if it is still available, and from where in small
quantities??  I need a piece about 2" X 7"         Thanks,  Ira.

I would recommend a think sheet of red acrylic. Inexpensive, looks good, scratches can be polished, and easy to cut. I bought some of this for a recent project: https://www.ebay.com/itm/273929530113

*thin* sheet. Thank you autocorrect.

Hi Ira, 

I buy acrylic from estreetplastics, or if I need something a little bit more exotic, inventables.com. For the filter material, I'm presuming you'd want something 1/16 thick or thereabouts? Alas, after a quick googling, I can't find red cast acrylic under 1/8 thick....

if u are looking for filters consider photo filters - along the lines of this:

or the "Rosco" equivelents. those are inteneded to be used over stage
or studio lights to control the colour of the light, and they come in a
literal rainbow of colours. they are fairly thin, and so would likely
need some sort of support. The material is cheep enough that you could
cut a band for each tube.
