The Optical Gas Imaging Recertification Examination is designed for the Optical Gas Imaging thermographer who needs to recertify an ITC Optical Gas Imaging certification. The prime candidate is a thermographer who has been unable to accumulate 32 certification renewal credits (by attending IR conferences, other IR courses, and/or writing/presenting articles and papers) during the 5 years of his certification validity. Payment is by credit card.

Some thermographers are surprised to learn that many wide angle lenses can be used for high magnification work. After all, the wide angle lenses have a larger IFOV and IFOV footprint, so how can they be used for small targets effectively?
Here is a typical example for a FLIR E60 camera (320 x 240 resolution):
| Lens FOV | IFOV (mrad) | IFOV footprint at 19.7” Working Distance |
| 25° x 19° | 1.36 | 0.03” |
| 45° × 33.8° | 2.59 | 0.05” |
The specs above don’t indicate that a wide angle lens is any better, in fact it has a larger footprint. So what gives?
Take a look at the thermograms below:
 | Here is a thermogram of a ruler taken with the standard 25° lens at its closest focus distance of 9.2”. Note how the scribed lines on the 100ths scale are fuzzy and merge together. The horizontal FOV is about 3”. This indicates that items this small cannot be resolved using this lens. |
 | I have enlarged the 25° image to illustrate the blurred lines on the scale. |
 | Here is the same ruler taken with a 45° lens. The scribed lines can clearly be seen and differentiated. The horizontal FOV is about 1.5”. What’s the secret? The 45° lens can be focused much closer to the target (1.2”). Hence it effectively can resolve smaller targets. |
Does a wide angle lens work as well as a dedicated close up lens? No, of course not. You might notice that the sharpest areas are in the middle of the image. A dedicated optic for close up work would be designed to reduce this effect while achieving higher magnification.
But as a dual purpose optic, when you need to do some close up work, a wide angle lens is pretty handy.
Here are some images from a FLIR P640 for comparison.
Thermography Fundamentals is a two day introductory class focusing on the fundamentals of condition monitoring/predictive maintenance for the new thermographer. Attendees completing all training course requirements will receive a certificate of completion and are credited with 16 class hours towards their Level I certification. (Certification requires 32 hours of class time).

Put the Power of Thermal Imaging in Your Students’ Hands!
A FLIR i7 thermal imager is one of the most powerful and flexible diagnostics tools a tradesman can carry today. And there’s a high demand from students eager to learn about this vital technology. That’s why FLIR is offering educators a 60% discount, making it incredibly affordable to add one to your program.
With an i7, you’ll be providing students an opportunity to discover the amazing ways thermal imaging finds problems that are normally invisible so they can readily see where to make repairs to save the day. This is cutting-edge technology that will go a long way to enhance their skills and help them gain a distinct advantage in today’s workplace.
Numerous Applications – Find hidden air leaks, missing insulation, moisture intrusion, electrical overloading, mechanical wear, and other thermal anomalies to help reduce energy waste, downtime, and safety hazards.
Beats IR Thermometers Hands Down – Get thousands of temperature measurements in every thermal image to show you the whole scene instead of working blind with only one spot reading at a time.
Exceeds RESNET Requirements – FLIR i7’s 140 × 140 detector delivers 19,600 pixels of IR resolution to capture the temperature measurements necessary to complete the thermal picture.
Compact Point-and-Shoot Simplicity – Light at 13 ounces (365g) for easy, one-handed operation yet tough enough to take a 2 meter drop and stow with other tools. Plus a focus-free lens and bright LCD to help you see the whole thermal scene clearly and cover more ground efficiently.
Camera & Training Support – Along with the i7, we’ll provide a DVD with downloadable guidebooks and videos plus plenty of help from FLIR and the Infrared Training Center to get you up and running. ITC also offers continuing education opportunities for your students as through online and classroom camera and thermography training courses.
For more information and to register for the program, use the link below: http://www.flir.com/thermography/americas/us/view/?id=57407
* Available to certified educators for classroom teaching at vocational and technical schools only, subject to approval by FLIR.
Are you a home inspector interested in adding infrared thermography to your list of services? Do you already own an infrared camera and want to learn where and how it can be used for home inspections? Then this course is for you!
We start out with just enough "science" to get you into the groove, then its on to applications: why they work, how to do it, and case history examples. The course is divided into the following sections:
Description
FLIR Tools is a software suite specifically designed to provide an easy way to update your infrared camera and create inspection reports.
Objectives
At the conclusion of this course, learners will be able to:
Complete any free online course, and get a coupon worth up to $278 towards any U.S. instructor led course or InfraMation Thermography Conference Registration.
We have some exciting news for you; we have developed a brand new Message board Forum so you can ask questions, get answers, and offer your expertise to the thermography community.

It is an entirely new format with a lot of new capabilities, here are some of them:
This course is intended for users of the FLIR Systems, Inc. Optical Imaging Cameras. Skilled users of the new FLIR GF Series cameras and the legacy GasFindIR camera can inspect over 3,000 connections per day. Current sniffer technology is limited to about 500 connections per day.
Students will learn how to setup and operate the FLIR Optical Imaging Cameras. They will learn how to optimally adjust their cameras for varying environmental conditions to find gas leaks. Students will learn under what environmental conditions gas leaks are most easily found, somewhat easy to find, and difficult to find.
Certification: Upon successful completion of the required activities listed below, each student will be certified as an Optical Gas Imaging Thermographer. 
Earn 2.0 IACET CEUs
Earn 20 ITC Certification Renewal Credits
Required Activities: Here is what is required to successfully pass this course:

Batesville Casket Co.
The Batesville Casket Assembly Plant located in Batesville, Indiana has two Seam Welders in their fabrication department. These Seam Welders are resistance welders that are designed to weld a continuous weld that holds the casket bottoms in place while making an air tight seal. Each Seam Welder runs proximity 27 units each hour and is in use for up to 10 hours each day throughout the week.
When a seam welder starts failing due to insulation failure you start seeing poor welds which in some cases don’t show up until the unit is built and vacuum tested prior to ship out. At this point to make repairs to the casket is costly due to disassembly and removal of the interior to gain access to the bottom.
Furthermore if one of the Seam Welders were to fail during production it would reduce production by 50%. The lead time for making this type of repair is two to three hours causing production losses estimated at eight to ten thousand dollars.
These Seam Welders are 16 volt DC / 20,000 amp resistance welders so being very low voltage and high amperage any insulation breakdown will cause the foot and lower wheel to overheat and eventually fail.
