New Flir products

With regard to the LEPTON lens block... I was initially surprised to hear that the elements were silicon wafer technology. I had previously believed silicon lenses to be limited to use below 8um. That made them useful for only short and medium wave thermal imaging cores. Thorlabs sell silicon lenses and their data sheets also suggest an 8um wavelength limit. A further wavelength limitation is then applied to the lens in the form of the AR coating. Thorlabs lenses cut off at 3um as a result.

As FLIR have used silicon lenses instead of GASIR, I can only assume that they have overcome the wavelength limitations of silicon 

This is an interesting development in itself as such lenses may be fabricated quite cheaply.

Interesting.
In this article the authors  described that the silicon lens must be very thin.
So they produced a  Fresnel lens on a thin silicon substrate!

Flir Lepton:
It's possibly that the fresnel patterns are on the back side of the (micro) lens?
I can't find a teardown of the lens...

[Fraser]

Uggggg ! I hope it isn't a fresnel lens design. Such do not make for great thermal imaging lenses.
Fresnel lenses made from certain plastics suitable for thermal lenses have been tried and the results have always been disappointing in terms of the image quality that they produced.

It would be great to better understand the LEPTON lens though.

I believe Mike may have a spare LEPTON 2 lens ? Maybe his Faxitron MX20 can image its cross section. He's a very busy chap at the moment though.

Lots of possibilities here.  Biggest problem of diffractive lenses (Fresnel) is that they are wavelength dependent.  Big problem for the nearly two to one wavelength interval of normal bolometer systems.  Perhaps FLIR is accepting the sensitivity loss that comes with a narrower waveband (since they are ITAR limited on delivered sensitivity anyway) and using that trade space for a lower cost diffractive lens.

I did dismantle the lens in my Lepton extreme teardown

[Fraser]

Thanks Mike. Great tear down   

My faulty F1G2 arrived at FLIR's returns dept on Friday. No news of a replacement being despatched though 

For info, Amazon are fulfilling the delivery of orders, but any repairs or exchanges are dealt with directly with FLIR. If I had been able to return the camera to Amazon, I would likely have received the new unit last week. Such is life. It's not a great start to my F1G2 ownership though 

Fortunately I am pretty much fully committed to my tidying of the garage. What a nightmare that is turning out to be. Next the shed, then the lab, and lastly the attic

hello, hope good news! we are receiving the FLIR ONE for iOS and Android begin of October.
discount code: flironenew
free shipment to Europe (we ship from Italy)
here is the link for the two models:
- Android http://www.batterfly.com/shop/flir-one-android
- iOS http://www.batterfly.com/shop/flir-one-ios

...

it's the same price when I order it directly on amazon :/

[frenky]

Well you don't get free shipping on Amazon so his offer is a bit better.

[Fraser]

Still no news on my replacement F1G2 Android   

Thinking of asking for a full refund. It's not as though I actually need another thermal camera.

Looks like GroupGets / PureEngineering has a Lepton 3 breakout board available.

I engaged the assistance of Bill Terre (VP FLIR) in getting a straight answer to what is happening on my replacement camera request.

Bill came through for me again and stated that a camera was ordered to be released for me last week. Bill advised that the Worldwide demand for the F1G2 was outstripping FLIR's ability to supply. It been a very successful launch !

If all goes to plan, I should receive my new camera this week.

Fraser

[Bud]

As VP FLIR, Bill may need to look into improving company's communication with customers.

EDIT: You know what, I take this back. They've done a good job obtaining feedback from the customers

EDIT2: Could Bill possibly provide his comments about FLIR "keeping in touch" with the customers that way ?

After many and many emails I finally got my Flir One Android camera shipped.

Now I'm starting a new battle with Flir support to get the invoice ... I'm sure it was a very hard time at Flir to ship all these cameras.

[mimmus78]

Anyone here managed to get an invoice for flir one android ? Flir support sent me a receipt of payment where even the supplier name and address is missing  ... I can guess supplier name but not address.

[arsenix]

Just got my new flir one android last week.

Anyone working on a linux driver for this puppy? Works nice in android but I'd really like to hook it up to a linux machine. Also would prefer not to have the MSX feature and just get raw thermal images.

I only bought the flir one android for my raspberry pi, but I'm waiting for delivery...

I have just heard from FLIR CS.

My F1G2 Android replacement camera is being shipped tomorrow.

Even with the help of Bill it has taken a week to get it shipped following an order to do so. FLIR must be having real issues meeting the demand for these units.

With regard to my experience buying a FLIR ONE..... It could certainly have been better. I can forgive a DoA but not the non existent communications from those dealing with the returned camera.

Not FLIR's finest hour I regret to say. If they read this thread.... A lesson learned, keep your customers informed, especially if there is a delay involved. Basic customer care 101 stuff.

I cannot praise Bill Terre enough though. He engaged with CS on my behalf and was always very friendly. A most approachable Gentleman.

Would this thread tolerate a quick derail?  I think the world's foremost Lepton hackers have all posted in it! 

I found this device, the "Torrey Pines Logic T10-M" which claims to offer a 30 Hz refresh rate on a 80x60 Lepton.  It also mentions an ITAR restriction on the product page.  There's two cheaper versions which have the 9 Hz refresh, so I don't think it's just a case of specs being interpreted wrong.  Is there such thing as a 30 Hz Lepton?

[Fraser]

Interesting find.

The units case is made on a 3D printer so it looks to be a small company producing it. Interested to read that it cannot see the Moon..... That's likely due to the low resolution and FOV.

I was not aware of a 30fps LEPTON. I am always wary when seeing a spec is 30Hz refresh as it can relate to the diplay module and not the camera core. This cameras does not attract comment on slow thermal image refresh though.

Thanks for sharing

Regardless if it exists, anything above 9Hz is ITAR controlled.

If you watch this video, it is very clear that the sensor really is 30Hz.

Here is another video w more details

Edit: and the guy is talking bullshit saying you can put it in front of your other optics and/or run a reddot through it.

[mikeselectricstuff]

  Is there such thing as a 30 Hz Lepton?

I'm told there is. The current Lepton outputs duplicated frames.

[encryptededdy]

Edit: and the guy is talking bullshit saying you can put it in front of your other optics and/or run a reddot through it.

Just wondering - why?

Surely if the screen and the lepton on this are aligned correctly, then looking through this through a red dot wouldn't disrupt the alignment of your sight?
