Years of industrial manufacturing experience have given technicians a trust that the minimum requirements necessary for certifying a product to UL standards are usually enough to ensure safe and reliable operation. In the case of infrared windows this is not necessarily true. UL 50V is the only standard defining infrared windows. It verifies that the [...]

How do YOU perform an infrared electrical inspection? For many people this is not something defined and utilized for ensuring every inspection goes correctly. Why not define the procedure on a work order? Can there be too many variables to write out a procedure? Taking the time to document the process on the front end [...]

Every infrared camera defines its Field of View (FOV) across a horizontal/vertical axis. You have two ways to determine the Field of View (FOV) on your camera: You can calculate the FOV using the formula: 2 x the tangent of ½ the angle x distance You can measure (and “map out”) the practical FOV with [...]

Many people are not aware that the detector in an infrared camera actually only reads electromagnetic radiation it receives in a specific range of wavelengths. In order to display this in a useful reading the camera makes several calculations in order to convert the actual data to a temperature. The emissivity and transmissivity (sometimes depending on the [...]
