M12 lens sourcing


I have a source or two for >12 lenses at 2-3mm, which are ok across
the visible band, and "usable" with 850 or 940nm illumination, but the
image is out of focus at the longer wavelengths.

Does anyone make achromats that cover down that low? I won't have
enough light to use aperture tricks, and I don't care if I loose some
focus on the blue end.

I'm not really looking for miracles, just trying to get the best out
of my systems.

Thanks
