$10 optics assortment

[Cyparagon]

Optical Lens/Mirror Chamber Type A-The Electronic Goldmine

Dicros alone make the pack well worth it, methinks.

That is quite a haul and a steal at that. But if it's just the dicros you're after DTR sells the projector optics that each have 2 dicros in them as well as other goodies, 2 for $9 shipped

Those polarized filters are pretty cool as well. If you look at the price of buying them they'd cost more than this set.

If I didn't have so many already from other sources I'd snatch this up.
