The following information ONLY applies to IR Windows, Heat Shields, or screw-on Close-Up lenses. Our cameras will automatically compensate for lenses that are factory calibrated (Ex.6°, 24°, 28°, 42°, 45°, 12°, etc.). The external optics selection should be off (set to 1.0) in the camera when using a factory calibrated lens. IR windows do not allow all infrared light to pass through, just as sunglasses or dirty windows don't allow all visual light through. Most modern IR cameras have a menu setting where the user can enter the external optic transmission rate to account for this. A common myth is that there is one rate for each lens material that comes from factory calibration or lab testing. Actually, the transmission rate for any optic material can change from location to location, camera to camera, window to window, or day to day! A transmission rate can be thought of as an average of many factors. In addition to optic material, some of these impacting factors are listed below: material core temperature target temperature (of the object you are measuring) camera response curve (can vary from one camera to the next) debris on the optics scratches on the optics impurities in the optics material environmental temperature reflected temperature from the surroundings possible presence of protective grids over the optic lifetime exposure to humidity distance and angle of the camera relative to the optics thickness of the optics Users are often unaware of all these factors because the effect from many of them is rather small and can be neglected without introducing unreasonable errors to temperature measurements. However, it is important to note that every IR material available today is affected significantly by several of these factors in any given installation. This is true for coated crystals, uncoated crystals, and polymer optics. The rule of thumb is that transmission is not a constant value and it should be measured periodically for every IR window in the field if accurate quantitative measurements are to be expected. How do you measure the transmittance yourself? All details can be found in the attached Technical Publication. Technical Publication 60

In chemistry, we studied something called dimensional analysis. Dimensional analysis is a method for converting from one unit to another. So first off we multiply the number of pixels by 1 over our DPI (in this case 300 DPI) then we multiply that by 25.4 by one inch (number of millimeters in an inch) Once everything cancels out we are left with a fairly nice, simple and easy to use formula.

Sorry, I was not trying to say your variant does not work. I was just pointing out how to use less code and take advantage of the UnitValue method.
