Manual instruments in production are gradually being replaced by automated optical measurement systems, where optimal illumination determines the test quality. A device that illustrates this transition is the ZEISS O-SELECT with an LED ring light from SCHOTT.
Bio-imaging and detection techniques that use non-linear optical (NLO) phenomena have led to great advancements, such as super-resolution images, label-free visualization of naturally occurring biomolecules, and greater freedom for working with in-vivo samples. This white paper discusses the importance of choosing thin-film optical components for NLO systems to ensure optimal signal strength, resolution, and image quality.
Micro-lens arrays are monolithic components manufactured from synthetic fused silica and a laser writing process, which are created for high accuracy array collimation and coupling. PowerPhotonic designs and develops these micro-lens arrays for applications involving coupling between laser sources, fiber and waveguide arrays, optical multiplexing, and optical switching. This application note discusses micro-lens arrays, as well as the technologies they are used in such as wavelength selective switching, WSS technology, and MEMS and LCoS switches.
Within so many diverse optical filtering applications, large-format (>100 mm diameter), narrow bandpass filters (NBPF) are required to be used alongside large collection optics in order to facilitate specific and selective analysis of a phenomena or the substance of interest.

Optics
Optics is an interesting subset of physics. It is the study of light and how it can be used in various industries from measurements to biology as well as photography to navigation. Optics is a fascinating field and we are just beginning to scratch the surface with what we know. One of the most interesting developments in optics is the use of fiber optics in the transmission of data. Light is used to transmit data across long distances and this has proved to be efficient as well as inexpensive.
Light is the fasted trailing particle in the universe and it is radiated from one point to the next in the form of waves. Light in a vacuum can travel at an astonishing 300 million meters per second, a speed that would take it to the moon in just about one second. Optics is primarily concerned with the use of light and how the light can be reflected, refracted, bent or manipulated in just about any way. The unique nature of light gives tremendous benefits in using it in various industries. Optics is no one of the ways where light can be used to store data. It seems that anything electrons have done in the past, light waves are able to do, just able to do it faster. In the beginning copper cables were used to transmit electrical pulses in network data transfer. While at that time it was a breakthrough, it was comparatively slow to the movement of light through fiber optics. Once fiber optics replaced, broad band speeds were achieved. All thanks to optics. The uses of optics can advance further with headway being made in fields of defense as well as medicine. Optics are now being used to return sight to the blind as well as create sight for robots.
