Optical systems use lenses to focus, collimate, expand, collect, and image light. Ranging from convex to concave, and bestform to aspheric, any lens selection must be made with the utmost consideration for its purpose as well as its required quality. This white paper delivers a review of singlet spherical lens shapes, and guidance on deciding the best lens characteristics for each application.
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.
Raman spectroscopy plays a huge part in the analysis of materials such as explosives in the field, pharmaceutical ingredients in the lab, and changes in genetic material, proteins, and lipids in clinical settings. Utilizing non-elastic scattering of laser light from a molecule to probe the molecular structure and create a vibrational transition in the sample, a molecular fingerprint is gradually built up. There are multiple wavelength analysis selections that can be used for a wide variety of applications. This application note discusses the benefits of using each wavelength, and presents different applications they are used for.
Edmund Optics offers a large variety of precision parabolic, spherical, and flat mirrors with an array of metallic and dielectric coatings to suit all application requirements in different regions of the spectrum. Standard metallic mirror coatings include protected aluminum, enhanced aluminum, UV enhanced aluminum, DUV enhanced aluminum, bare gold, protected gold, and protected silver. This application note introduces their first and second surface mirrors, enhanced metal coatings, and available custom coatings.
The optical quality of aspheric mirrors is commonly specified by their surface accuracy and reflected wavefront error. The surface error is the deviation of the surface from its perfect form, while the wavefront error is the deviation of the resulting reflected or transmitted wavefront from its perfect shape. It is often assumed that these tolerances are related to each other by a simple scale factor. However, that is not the case when it comes to aspheric mirrors. This application note compares surface accuracy measurements with wavefront error measurements, and provides an application example on using them in off-axis parabolas.

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.
