Long-Range Fast Photometer FPM02-LR
The Long-Range Fast Photometer FPM02-LR is an advanced, powerful, and highly accurate device designed for the same purposes as the FPM01-LR Fast Photometer, with the added capability of measuring at significantly longer distances. This additional detector is an essential tool for professionals in need of precise measurements over extended ranges.
The FPM02-LR features a unique design that allows for easy and accurate aiming of the detector at long distances. The powerful telescope enables users to zoom in on the target and place the detector on the eyepiece, ensuring direct and precise aiming. This innovative design makes it simple to use even in challenging situations.
Like the FPM01-LR, the FPM02-LR exists in two modifications: one measures in the visible light according to CIE specification, while the other measures in the area of visible and infrared light (up to 1100nm). This versatility ensures that the FPM02-LR can meet the needs of a wide range of applications.
In summary, the Long-Range Fast Photometer FPM02-LR is a powerful, accurate, and user-friendly tool that extends the capabilities of the FPM01-LR Fast Photometer, allowing for precise measurements at distances beyond 1km.
