Application Notes

Ophthalmic Surgery

The laser is particularly suited to ophthalmic surgery since it can provide a non-contact method of interacting with the cornea or even the interior of the eye, including the lens and …

Application Notes

Super-Resolution Microscopy (STED and PALM)

One super-resolution approach is called stimulated emission depletion (STED) microscopy. This technique uses a confocal microscope and a diffraction limited excitation beam that is …

Application Notes

LiDAR

LiDAR is an active remote sensing technique that is similar to RADAR but, instead of using radio waves as a radiation source, it uses laser pulses. In this technique, a laser source …

Application Notes

Flat Panel Display Manufacturing

As the flat panel display market moves from LCD to OLED display technology, laser patterning and cutting of heterogeneous materials (comprised of multiple organic material films) with …

Application Notes

PCB Manufacturing

Lasers are routinely used in a variety of PCB manufacturing processes including via drilling, depaneling, profiling, laser direct imaging, repair, trimming, and marking. Laser processing …

Application Notes

Solar Panel Manufacturing

Crystalline-Silicon solar cells are the predominant solar cell technology used in fabricating solar panels because of the availability of silicon, well-developed manufacturing processes, …

Application Notes

Semiconductor Inspection

In this application note, we provide a brief description of the basics of wafer and reticle inspection techniques and discuss the characteristics of current inspection tools.

Application Notes

Semiconductor Lithography Overview

Lithography is defined as "a method of printing from a flat surface (such as a smooth stone or a metal plate) that has been prepared so that the ink will only stick to the design that …

Application Notes

Deep UV Photolithography

DUV technology for photolithography is exclusively based on projection optics since the pattern on the photomask is much larger than the final pattern developed on the photoresist.

Application Notes

Extreme UV Photolithography

EUV lithography is being developed to fulfill single-exposure patterning requirements at feature sizes below 22 nm. Unique to this technology is the nature of the light source.

Application Notes

Semiconductor Manufacturing Overview

This application note provides a brief overview of semiconductor manufacturing and describe the various optical techniques used to define, inspect, and measure feature sizes and layer …

Application Notes

Laser Micromachining

Laser machining is a non-contact process that can achieve higher precision and quality, smaller features, improved consistency with no tool wear, and possesses the flexibility to machine …

Application Notes

Laser Macroprocessing

Laser macroprocessing is defined as the machining of metal parts with thicknesses greater than a mm to produce large features with multi-mm dimensions. The process uses high power lasers …

Application Notes

Real-Time Laser Power Measurement

Only when performing optimally can laser systems guarantee the most cost-effective production of high-quality components. Even the smallest deviations in beam adjustment or focal position …

Application Notes

Non-Contact Laser Beam Measurement

A non-contact method developed by MKS Ophir is based on Rayleigh scattering. Rayleigh scattering is the scattering of light by particles that are smaller than the radiation's wavelength, …

Application Notes

Thermal Imaging

Thermal imaging techniques involve discriminating between various objects in a scene based on their respective differences in temperature.

Application Notes

LiDAR Application Examples

The accuracy and detail provided by LiDAR makes it an essential component of many applications that help local authorities and other land management organizations in their areas of …

Application Notes

Data Communications

here has been a tremendous increase in the volume of internet-based digital data communications over the past decade, with global cloud data center traffic reaching 8.2 zettabytes in …

Application Notes

Advanced Bioimaging Overview

Multiple advanced bioimaging techniques have been developed to improve the axial resolution and allow a true 3D representation of the sample to be reconstructed.

Application Notes

Photoacoustic Microscopy (PAM)

Unlike the pure optical microscopy techniques, PAM takes advantage of the weak acoustic scattering in tissue and thus breaks through the optical depth penetration limit (~ 1 mm) in …
