Description: The eyepiece is an integral part of any compound visual system. Its purpose is to magnify the real image formed by an objective or intermediate relay system. For this reason, the eyepiece design ...

Description: Often, a customer struggles with contrast and resolution problems in an imaging system, while underestimating the power of proper illumination. In fact, desired image quality can typically be met by ...

Description: Test targets can be used to evaluate or calibrate an imaging system's performance. Correct assessment of an imaging system is used in certifying proper measurements, establishing a baseline between ...

Description: Over the years, we have answered countless questions regarding lens performance. Of those questions, none have been more difficult to define than requests for depth of field. The reason for this ...

Description: An optical flat is a precisely polished flat surface, used as a reference against which the flatness of an unknown surface may be compared. Edmund Optics offers both single surface and dual surface ...

Description: Many scanning, alignment and spectroscopy applications require optical power metrology coordinated with motion, with positioning precisions that often necessitate piezo-class motion devices. ...

Description: Many medical applications have need of 'broad' irradiation patterns, but benefit from small diameter fibers to provide minimal invasive surgery. These applications also benefit from using the low ...

Description: The high power diode laser systems, but must be flexible, and have not only good strength but also good fatigue behavior. Th with their laser diode bars and arrays not only require special fibers to ...

Description: How can you tell which side of an optic is coated? Let's say you consult the print and it says Side 1 should be coated. So which is Side 1? Assuming your design team anticipated this question, you ...
