From this Article:
Optical coatings can be critical in an application. Coatings are used to either increase the transmission of light by reducing back reflections (as in the case of lenses, windows, etc.) or to increase... (View Full Article)

From this Article:
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... (View Full Article)
(Lasers)
From this Article:
The basic structure of any laser is based on an active medium (either a gas or semiconductor) contained between two reflectors. A laser's reflectors contain light by oscillating it through a medium... (View Full Article)

From this Article:
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... (View Full Article)
(Lasers)
From this Article:
Our customers often ask us if a laser spot can be seen in their application. While such information can be a critical factor in anything from alignment to targeting applications, the answer to this... (View Full Article)
(Microscopy)
From this Article:
Compound microscopes differ from simple magnifiers in that there are two separate magnification steps that occur instead of one. The objective lens is nearest the subject under observation and... (View Full Article)
(Lasers)
From this Article:
Laser Beam expanders are designed to decrease the laser's beam spot size at large distances. There are two main types of beam expanders: Keplerian and Galilean. In its simplest form, the Galilean type... (View Full Article)
