The Close Focus (CF) lens for compact pyrometer allows precise measurement of small objects in short distances, with the minimum spot size dependent on the sensing head version used. These lenses have specific transmission values, ensuring minimal signal loss during measurements. There are two types of CF lenses: those with an internal thread, which screws directly onto the sensing head, and those with an external thread, designed for screwing into the massive housing or laminar air purge. The CF lens can be easily installed by turning it until it reaches the end stop. For optimal performance, keeping the lens surface clean from contaminants is crucial. It is compatible with all LT, 1M, 2M, 3M, and 4M models.
