    Default Group buy Edmunds Optics window 3"x3" x 3mm

    Hi Guys,

    I'm about to buy an Edmunds optics Window (3" x 3" Size 3mm Thickness, AR Coating NT46-101).
    http://www.edmundoptics.com/onlineca...productID=1919

    Just checking if anyone is interested in a group buy as there is a significant price
    break for buying 6 pieces. Also the shipping is the same for 1 or 6.

    When I view the Edmunds site and state my location as Australia it shows the
    prices in Singaporean dollars so bare that in mind when you look at the links above.

    Here is a breakdown of the cost to buy one or six converted to local currencies as of
    20th june 2010.

    1x Edmunds optics window 3"x3" 3mm Thickness, AR Coating NT46-101 + shipping to
    Australia is

    Subtotal: SGD$30.78 = AUD$25.49 = USD$22.22 = EUR17.94 = GBP14.99
    Shipping: SGD$45.00 = AUD$37.27 = USD$32.49 = EUR26.23 = GBP21.92
    Total: SGD$75.78 = AUD$62.76 = USD$54.71 = EUR44.17 = GBP36.91

    Now if we buy 6 it looks like this;

    Subtotal: SGD$147.72 = AUD$122.34 = USD$106.66 = EUR86.10 = GBP71.94
    Shipping: SGD$ 45.00 = AUD$37.27 = USD$32.49 = EUR26.23 = GBP21.92
    Total: SGD$192.72= AUD$159.61 = USD$139.15 = EUR112.33 = GBP93.86

    Soooo the price per unit to Australia to get to me in Perth is:
    SGD$32.12 = AUD$26.60 = USD$23.20 = EUR18.72 = GBP15.64

    Price per unit to ship to Europe, the US and most countries is around $10USD
    To ship within Australia and NewZealand is around $8-$9AUD.

    All these shipping rates are by standard air mail.

    Approximate total cost to Australia or NZ per unit including 2.5% paypal fee is
    AUD$35.47

    Approximate total cost to US per unit including 2.5% paypal fee is
    USD$34.03

    Approximate total cost to Europe per unit including 2.5% paypal fee is
    EUR27.46

    Approximate total cost to UK per unit including 2.5% paypal fee is
    GBP22.94

    If you are interested, have a look at buying one direct yourself from your country.
    If it turns out cheaper, go for it. If this group buy works out cheaper for you let me know.

    If anyone was wondering what size window they need, have a look at the pics below.
    This is a rough layout of my projector design showing a 3" x3"x3mm window positioned 40mm in front of the scanner shafts axis. The transparent scan area represents a 54deg scan angle.

    This window should work for most builds except maybe the DT40 wides and the like.

    I'll be placing my order in about a weeks time.

    Hope this helps

    hi Andy,

    Sweet
    Sounds like this stuff can't be beat for the money.

    MMMM....2.6watts of red very tasty.

    What red are you using?

    Wow that's Awsome!
    I was going to buy all turnkey modules before the blue revolution.
    The 2w Blue Kwant/1.8w RGBlasersystems module I was considering will be a home made job now.
    At this stage my plans are for a 3.2w red from Kvant.
    I love the challenge of machining And assembling precision gear
    but I think I'll tap out on building a red of this scale.

    It will be a while off till I buy my red so maybe they will develop some higher power
    red diodes by then but for now the cost/results eqation favours Kavant for me.

    I'm looking forward to the blue build though.

    Hi Jaycey,
    I'm still a bit new to forums and the lingo. What does LOC mean

    Awesome, thanks Kit

    LOC is for Long Open Can. Long is the length of the die and Open Can is the style of diode. The blues are closed can or LCC. Cmy understanding is that closed cans are more desirable (provided you can equal the power) as there's less risk of dirt getting onto the die which could kill the diode when lasing.

    I started a thread a while ago to capture all of the diode related terms and points to note (when I knew very little). I need to update that with my acculuated knowledge and invite comment.

    Thanks for that Tony

    I'll stay tuned for that post

    The revolution has prompted me to
    seek a much deeper understanding
    of diode/optics/driver technicalities.

    Speak soon
