A recently granted patent (Publication Number: US11885950B2) discloses a light source module designed for microscopes. The module includes a light source emitting illumination light, a light blocking shutter that can be moved in and out of the light path, and a light sensor integrated with the shutter to detect the intensity of the light. The patent also describes a method for illuminating a sample using this module, where the light source is controlled based on the intensity detected by the sensor to prevent excessive light exposure to the sample. Additionally, a calibration method is outlined, involving emitting light, detecting intensity, and determining calibration characteristics for the module.
Furthermore, the patent details the integration of multiple light sources and a beam combiner in the module to provide a combined illumination light. The module includes a controller to manage the light sensor and source, adjusting the intensity of the emitted light accordingly. The method for illuminating a sample involves a sequence of steps including moving the light blocking shutter, emitting light, detecting intensity, and adjusting the light source. Additionally, a predictive maintenance procedure is described, where the light source emits light at maximum intensity, and maintenance information is generated based on the detected intensity. The calibration method involves emitting light, detecting intensity, and determining calibration characteristics based on reference power and intensity values.
