Wide angle lens

[ldapkus]

I will ask him again tomorrow for clarification. He explained that calibration was not needed and changed the interchangeable lenses on my T300 and a P600/620. Either he is wrong or you got screwed by the service rep that convinced you that your calibration was required. I've got a while to go before I get into quantitative work.

My T400 is several years old. When I inquired about a wide angle lens
I was given a price for the lens and a price for calibration to that lens.

Granted things have changed with the newer cameras having more standard features.

n addition to the added versatility of manual and autofocus optics, optional FLIR lenses are auto-recognized by the camera eliminating cumbersome calibration routines in the field. An unmatched spectrum of easy-to-swap, close-up, wide angle and telephoto lenses are available: 6º, 15º, 45º, 90º, 2x, and 4x

Either he is wrong or you got screwed by the service rep that convinced you that your calibration was required.

Yup, thus my inquiry!

You are not charged for camera calibration if your camera was recently purchased.
If you have not had your camera calibrated to the new lens, they should do it for free because you just purchased that camera.

I purchased the wide-angle lens so that calibration (which was required to replace my camera parts) could be performed while the camera was in the shop.
I also upgraded my camera to a T-400 because the camera program had to be reinstalled anyway.

I got a discount on these options and service because the camera repair required software and calibration anyway, as well as saving several hundred dollars in shipping/insurance fees to send the camera in.

OK, we were told that cameras that are equipped with "smart lenses" such as the new T300,T400, P 600 series which comprised 90% of our participants, do not need additional calibration or re-calibration when changing out lenses. The lenses swap info with the detector and work together. One participant asked if he could simply use a smart lens from a co-worker who had the same series camera and it was confirmed that all he had to do is install the lens and the camera would sync with the lens. Calibration is recommended when the camera drifts out of calibration or yearly whichever comes first.

OK.

Someone needs to advise the "lab"!

I work for Extech (a division of FLIR) and I didn't agree with the above statement and thought it was misleading so I checked with the service manager at FLIR to be sure. The above information is partially true. Here is the service manager's response: "Joe (Gierlach) is not giving all the details. Assuming a camera has a cal file with certain type of lens, yes you could borrow another identical lens and cal would be good. If the borrowed lens type is different and the camera was never calibrated to the different lens, then no you could not borrow a different type lens and have calibration in spec."

What this means is the standard lens that comes with the camera should work on any camera because all cameras are calibrated for the standard lens and contain a cal file for it. When you order an optional lens, it has to be calibrated to the camera. Then the camera has a cal file for that specific lens. That's the only way it will work. So lenses are interchangable between cameras if the cameras have been previously calibrated to that specific type lens before. I hope this clears it up.

First time posting a reply so hopefully I did it correctly. (I didn't want anyone to be misled about the incomplete calibration information).

All I know is it did not cost me any extra I purchased the lens and the camera together and they stated shipment would be delayed about 3 days due to calibrating the lens to the camera. That may have been a russ as to why the camera had not been shipped don't know

What I was told when I bought my B400 w/high temp option was that the imager software needed the file installed to calibrate the specific degree lense. If an imager had that file installed it could use that lense.

[David A. Andersen]

Cal free in first 3-60 days of camera purchase.

Larry, you have a "B-xxx". It has different software to start with. Year of Mfg determines what is on board also.
