Confocal Detection Principle
Confocal Laser Scanning Raman Microscope has become a widely recognized research instrument in recent years. Confocal microscopy offers several advantages over conventional wide-field optical microscopy, including the ability to control depth of field, elimination or reduction of background information away from the focal plane and the capability to collect serial optical sections from thick samples. The image of the extended sample is generated by scanning the focused laser beam across a defined area.
The pinhole aperture rejects the residual scattered rays originated from any out-of-focus points on a sample.
We have created the instrument that is right for you
