Has the hackabiliy of the E4 made you buy one :  

Yes, I was already looking at the competition at a similar price, but the hack swung it to E4

Yes, I'd not considered buying a TIC before, but 320x240 resolution at this price justifies it (as either tool or toy!)

Yes, I was going to buy an E5/6/8 class of unit but will now get the E4

No, but am looking out for a cheap i3 to hack

Who knows the diameter of the lens from Flir E4? I made  telephoto lenses. Perhaps they will be working with Flir E4 . If it is less than 12.5mm.

The Ex series uses a 6mm diameter lens that I have already used with 12.5mm diameter auxiliary ZnSe lenses for CU work.

Thanks for the answer. One more question. Is it good that the holder?

That mount certainly works well for close-up lenses but it is not really that suitable to hold any sort of weight as it can pop out of the large case aperture into which it uses a friction fit.

With a small diameter auxiliary lens and the wide FOV of the Ex series, it is important to place the lens as close as possible to the cameras fixed objective to avoid vignetting. Some of the alternative lens holders position the auxiliary lens too far away from the objective as they are deigned for 20mm diameter lenses only.

I have some beautifully made aluminium close up lens holders made for me by a fellow forum member. These friction fit into the neoprene aperture that surrounds the lens objective. Sadly they are also unsuitable for any significant load bearing, and so unsuitable for your lens.

I believe that the lens holder that you referenced is a good start point as it spreads the load well, but it will likely need some elastic bands or similar retainers to firmly secure it t the camera.

Hi everyone

I created a step-by-step guide with pictures how to permanently upgrade i3 & i5 to i7 specs & how to add the extra measurements menu.

I made a lens holder for Flir e4. His mount I do not like. Not reliably. I want to make a secure attachment. I do not have the opportunity to make the necessary measurements of the size. Who has the E4. Please tell us the dimensions. Needed are highlighted in red in the drawing. I want to make the bracket as in the second figure. Thanks in advance.

Can you repost a zoomed image of the top left dwg? The one with 5 measurements of the side view. Hard to see line detail.

Please. I increased the image. I do not have the E4. Maybe someone will offer a better lens mount. I will have the opportunity to take Flir E4 only a few minutes to test the zoom lens. Therefore, immediately I want to make a good mount.

Hello!

I have an E4, and I'm wondering if any of the experts here have seen an E4 behave this way

  • When the camera performs a NUC, and held just slightly upwards, the thermal camera gets *stuck* and there is no more thermal image on screen, all is at equilibrium
  • Upon lightly tapping on side of camera body, or *occasionally* when the camera either manually (by pressing arrow/archive button) or on it's own it will RIGHT or FIX itself, meaning the camera goes back to normal

As I have another device, a T-Series, the NUC process is a bit more *mechanical* sounding... I'm wondering what might be getting stuck in there that would become free or move when tapped or another NUC is done??

Also, as I purchased this device with the software enhancement AND have access to other & higher grade devices, it would seem the thermal sensitivity does NOT get upgraded IMO. I've compared to T-Series (not fair I realize) and I'm nearly certain that while the detector resolution is enhanced, that either the balometer is lower quality OR the sensitivity is still at .15 vs the E8's .06

Anyone have any ideas.. could some dirt or similar get in front of whatever mechanical apparatus is part of the EX's NUC process?

Most likely to be the mechanical Flat field correction shutter getting stuck. Dust ingress is not normally a problem.

You can see the shutter operation if you unscrew the lens. You will  likely need the lens tool though.Rectification requires disassembly.

I have had cameras suffer FFC shutter spring detachment which makes them stay in the wrong position once the FFC is completed.

Thanks Aurora, I think I tend to agree.. shutter intermittently getting stuck. I'm wondering if parts are available or ? I could mail to Manu for repair, but there are pros/cons to such..

Thanks again!

No parts available for repairs.

FLiR will repair cameras that are under warranty, but if you bought it second hand, the warranty may, or may not be valid.

FLIR will upgrade the camera to the latest firmware as part of any repair.

The FFC shutter is a simple design. It may just be a simple alignment issue, or a spring that needs to be re attached. There isn't much to go wrong with it.

I also wasn't happy with anything available on the web as a lens holder, so I designed my own. It's still only intended as a makro extension (for PCB / electronics analysis) but I think it would be rigid enough for a small telephoto configuration as well (see attached photos - don't mind the dust please). So far the bottom of the adapter is flat, the next generation will have a ridge around the circumference since the bezel of the E4 lens is a little convex and so the holder will tilt a little horizontally (no issue at all for the macro lens).  If you're interested in this configuration, I'm prepared to provide the 3D file (STEP or whatever you like...)

Cheers,
Thomas

P.S. the lens is locked in place with a circlip on top of an O-ring

Thanks for the answer. One more question. Is it good that the holder?

Yes please share the files for 3D printer, I'd like to try it.

@turbotom,

Very nice lens holder sir :)

I would love the 3D file for my personal use. The original file format (in case I need to modify it) plus the STL would be great.

Best Wishes

I'll be glad to get 3D file. This is a beautiful solution to the macro lens. But even so, I think that the additional fixing on the sides give rigidity. If you have time please make the necessary measurements to me. I want to make the side latches.
And I have more questions:
1. ABS plastic shrinks during cooling. You make amendments to this problem?
 2. What is the diameter of the lens you used the?

On ABS shrinkage..... The 3D printer calibration routine involving a test print compensates for the shrinkage. At least it does on my UP! Mini  :)

Here's an archive containing the STL and a STEP version of the lens holder:
http://www.turbinemuseum.de/files/Flir-Linsenfassung.zip
We've got a Zortrax 3D printer at work that I used to produce these parts and I don't have to bother about shrinkage at all, yet warpage is sometimes a problem, depending on the filament material used and the orientation of the model.

Hope this helps....

Cheers,
Thomas

P.S. lens diameter for this holder is one inch.

Okay, near as I can tell, the three measurements from the face (left side of your drawing) to the side of the camera are 0.175", 0.620", and 0.763".
The vertical height of the straight section of the "FLIR" indent on the left side of your drawing is almost exactly 1.25".
I'm not sure what you're looking for with the green lines ("Depth?") on your drawing. If it's the depth of the "FLIR" indent, that measures about 0.060" (the plastic panel bearing the "FLIR" logo is 0.060, but the inner bevel of the indentation is slightly deeper than that.

Thank you. I do not know of only two sizes. In the drawing, they are with question mark. Please write them.
