Filters
Filters in optics and photonics is a device or material that selectively transmits light of certain properties,while blocking other light. Filters are essential components in a wide range of optical systems and have various applications across multiple fields. Filters can more precise control over the light that reaches the detector, sensor, or eye, thus enhancing the outcome or information gained from optical systems.SIMTRUM Provides different types of filters and filters sets.
