Optical Sensor Design
At the most fundamental level a sensor is a device that measures a physical quantity, such as water level or torque, and then converts it into a signal that can be read or interpreted by an instrument or observer. Sensors allow us to monitor the natural world and permit us to take appropriate action. At Lechtzer Incorporated, optical sensors are developed to measure the response of materials to various portions of the electromagnetic spectrum. These devices are used to sense phase changes, optical absorption, and variations of the environment, such as temperature or pressure, which can influence the propagation of light. These sensors are then incorporated into automated or robotic systems in conjunction with other sensors to comprise the critical sensing system of the data acquisition side of the instruments.
