The sensor glass that comes installed on the CMOS & CCD cameras is used to protect the sensor from damage, mechanical issues, and environmental hazards such as dust. The sensor glass is important in protection of the sensor, but can also be limiting in terms of the quality and usability of the sensor for certain applications.
Sensor glass removal is an integral part of any system needing the path of least resistance in their optical path. These are for tasks requiring the highest degree of accuracy. For example, you may want the sensor glass removed when you are conducting laser profiling; this will be able to get the most detailed image possible with no artifacts.
Applications, but not limited to:
Laser Profiling: Capturing, displaying, and recording of the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path.
Interferometry: a measurement method using the phenomenon of interference of waves (usually light, radio or sound waves).
Ultra Violet Applications: lowers the lower end of the spectral sensitivity (350nm to 100nm)
Medical: The cover glass restricts the range of angles needed by the vision system for its field of view. The medical field requires a wider field of view and more oblique angles to accurately obtain the desired image.
**Wilco Imaging does not recommended that you try to do cover glass removal without proper training, because the risk of damaging the sensor is fairly high.**
