Difraction gratings from O-like, 4.80$!!!!

[Deleted member 8382]

I saw Susie was selling difraction gratings mounted on 30mW lasers, so I thought It would be great for all of us to buy one of these. The problem is that we would need to buy at least 20 units, but for the price I'm sure we will reach the ammount soon. I was planning to buy the 4.80$ one but if anyone need the others we can make 2 buys

We will decide who recive and distribute them later, here I atach the mail I got from susie:

"Dear Albert ,

There are two dimension for grating ,one is 5*5mm used in pen laser .
and the other is 12*12mm used in torch laser .
so here below is quotation for each

1.5*5mm is $4.80 (>20pcs)
2.12*12mm $6.00(>20pcs)




Thanks and Best Regards

Susie"

Yours,

Too expensive for such small gratings. Maybe if they were like 3" x 3" then I'd get lol. Really though, it seems better to order the 30mW from another website (Focal Price) for only $15 shipped. Then you can take out the grating.. and still have a 30mW pointer for about $10!!

I wouldn't recommend focal price-- they have gotten one of my orders wrong for 3 months-- and they still have not fixed it...

Is it $4.80 each or what? Cause O-like has a 10pack of the 6x6x1mm for $20 shipped: http://cgi.ebay.com/10pcs-Red-blue-green-laser-star-diffraction-grating_W0QQitemZ170332695544QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item27a89eabf8&_trksid=p3286.c0.m14&_trkparms=72:1205|66:2|65:12|39:1|240:1318|301:1|293:1|294:50
