The main body of the 7-L series wavelength adjustable monochromatic light source is comprised of a broad spectrum light source (deuterium lamp, halogen lamp, xenon lamp, or composite source) and a wide spectral monochromator. Additionally, to eliminate multi-spectral interference, it is equipped with a 7IFW6 filter wheel.
Users can choose to equip collimation or converging lens groups at the light source exit according to their requirements. The 7-L series can also be equipped with an adjustable diaphragm to modify light spot size or energy. For users requiring chopper connections, an exclusive holder for fixing the SR540 chopper is available. Customization services are offered for special users, such as equipping the device with choppers of various specifications from SIGNAL RECOVERY company for connecting to optical fibers with different specifications.
