Optima lens group buy?

**dave** · 08-04-2011, 07:17

Just a feeler. I could use a few, and it seems like there is interest around.

Who is interested in a few?

**taggalucci** · 08-04-2011, 07:31

Yes please Dave, I could do with 4 to start with (plus 4 of your lens barrels too).

**hivelaser** · 08-04-2011, 07:39

Yes i would be interested too, what price are we talking about, i can spend about $200 on that.

**andy_con** · 08-04-2011, 07:58

rough cost?

do we have any data from these lens on open can diodes?

**steve-o** · 08-04-2011, 08:12

Dave, are these aspheric ar coated for red? Any specs or p/n? I may be interested pending specs/ cost ..

**dave** · 08-04-2011, 08:19

http://optima-prec.com/molded.htm pn: 305-0464-780

They have a MgF2 coating for red.

Price is listed on the website at $17.20USD, I have just emailed for qty pricing..

**hivelaser** · 08-04-2011, 08:26

Do they have a coating for blue as well?

**steve-o** · 08-04-2011, 12:32

I'm in for 2 :]
Do you have mounts for these Dave?

**LaNeK779** · 08-04-2011, 12:55

i have some on the way, but if a nice quantity discount applies, i could use another 4-6 (+lens barrels)

dave, i think we should point out that these lenses need a dedicated lens barrel, as they are slightly smaller than the 405-g-2

Now that would fill out my order very nicely ! I would definitely take some along with some barrels and perhaps a few 405-g2 if you still have any.

@ andy_con I think edison has data, and I will also have some (also for 637nm) soon once my edison kits arrive!

Cheers

**LaNeK779** · 08-04-2011, 13:17

edison has data, solarfire has data and planters has data and they have all posted here. even i have posted a couple of lines

maybe mr con is just to lazy to search

it is a good lens. if you want to get an idea, put a 405-g-2 in front of a LOC and then imagine 8-9% more output

**edison** · 08-04-2011, 14:28

I have 100 pieces in stock anyone who needs them let me know.

Dave if you need a few just send me a PM

**hivelaser** · 08-04-2011, 14:39

Edison i think the groupbuy is that we get it to a cheap price, everyone knows you have them in stock, just a little to expensive you selling them

. Just saying.

**megaton** · 08-04-2011, 14:52

Hi Dave

Im in for 4 or 6 Lens (+lens barrels).

Thanks and cheers,
Ed

**edison** · 08-04-2011, 14:53

You need to buy at least 200 pieces to get a few bucks off.

Also service comes with a price. If i sell a lens and its not good i send a new one that cost me a lens and shipping cost. Did you calculate that also?

For most hobbyist everything is too expencive. But they expect service also. Service comes with a price. Sure i,m happy to help people with building their projectors like michelrietveld, give stuff that i manufactured and not use anymore for a few bucks away. I build even an 8 combiner for Hobbybob for cheap as chips but he suports me even he sometimes hardly can afford it. Dave helped me with his retainers and so i,m happy to return the favour.

so exactly what favour are you returning ??
ohh that would be selling us the lens for somthing like 30 euros when they will be half that in the group buy
yeah nice thread invasion.............
if any one should make somthing from this it should be dave ITS HIS THREAD

**planters** · 08-04-2011, 17:26

Just an update on the MOUNTED Optima lenses I have been using for several months. The strange 3/8x64 thread that Optima provides requires a tap that I was only able to source through Optima and results in a rather loose thread fit. The thread adhesive that helped to minimize this still allowed a small amount of pointing drift. It was not until I ordered (from Optima) a set of empty (no lens) mounting rings ($6 each) that when placed into the deep threaded holes as retaining nuts did all the lenses remain rock solid. If there is a good mounting option alternative, I would go that way.

**edison** · 08-04-2011, 17:32

No offence but i was the one who discovered the optima lens. I bought them and tested them and shared the info.

I offered my lenses to dave because he made 150 retainers for a nice price so that,s why i said that i,m happy to return the favour.

I could develop the KIT because people bought stuff
from me so that i could develop and manufacture the Kits so that people do,nt have to buy an expencive kvant. So the spend money isn,t lost at all. But i know how it works badger, if you can get an expencive laser with a price of 1000 pounds in your own country and on the other side of the world a chinese guy sells it for 20 pounds les you will buy that one. That way your
ruin your own economy. But he who cares as long as you have your laser

**edison** · 08-04-2011, 17:37

Planters, your a hero. At least i know that its better to stick with the retainer from dave. I just finished a quad without using flexmounts and i wanted to have the retainer version from optima in it. I think i will stick with that one for know.

**taggalucci** · 08-04-2011, 18:03

@Edison, I think the issue folks have is that you are asking a premium for items you re-sell. Please look up "value add" and "competitive pricing" to gain a better understanding of these concepts and how they can improve your proposition.

I also suggest not having a crack at your customer base when they pull you up on your current pricing and customer relationship management issues.

**Solarfire** · 08-04-2011, 22:17

Up to 20, with or without barrels, depending on price.

i suggest you read through most of the group buys that have happend over the years on here.
all of them done to better the laser community as a whole none of them done at a profit,
some have even lost money, we are hobby guys and one big famliy and we all help each other out.
this is not economy ruining (sarcastic) stuff we are doing here edison.
just a few guys playing with lasers as a hobby
being arrogant with the i discoverd the lens crap is not cool ,so what you found a lens, if it was not you it would have been some one else that would have found it
if you want to be a friend to the laser hobby guys then be like everyone else and do it at cost
with a few % on top not double the price, people will love you more for it........

**dave** · 08-05-2011, 08:22

Hey guys,

It might be better if someone in the states can get the GB for lenses happening. I think if I did it, the cost of shipping from optima to myself would make the quantity discount pointless. In return, I could do a GB for retainers - I have about 30 in stock ATM, but ordering more is not a issue.

**hivelaser** · 08-05-2011, 09:57

I can handle it here in the US is no problem... You think if i inquire as a company i get it cheaper or should i do it as a individual.

Cheers
