Photometry & Colorimetry
In 1984, Buck Scientific developed its first new instrument, the Model 200 Atomic Absorption Spectrophotometer. Since then, our engineers have continued to develop new instruments based on the philosophy of providing excellent analytical performance and quality at an affordable price.
Our Atomic Absorption Spectrophotometers and Infrared Spectrophotometers are built in Norwalk CT. Both instruments have many happy users. It is very common for people not to need any servicing for 10 or 15 years after purchasing them. They are workhorses built to withstand tortuously corrosive environment like plating shops and mines. The infrared is loved by many around the world who do not have adequate air conditioning to run an FTIR. In these cases we are often their last hope, and the M530 costs about 1/2 the price of an equivalent FTIR, so customers save money and solve their problem at the same time.

Light is what nestles deeply into the molecules that make up matter, and makes it possible for matter to be what it is. Although its roots extend deeply into the origins of the world we live in, there’s still much that we don’t know about light. The knowledge that we gain in our quest for understanding will undoubtedly reveal, little by little, the “landscape” of our world in the most quintessential meaning of the word. In our pursuit of light, we at Hamamatsu Photonics are building a foothold for exploring what is still unknown to mankind, and for creating new industries for the future.
In our Industrial Development Laboratory, built in 2008, we carry out research in such areas as power generation and material modification using light energy.
Hamamatsu’s joint research successfully forms a multi-layered polycrystalline ceramic surface through laser shock compression technology.
Hamamatsu, Japan July 17, 2015 The Graduate School for the Creation of New Photonics Industries, an academic institution affiliated with Hamamatsu Photonics K.K., has announced the discovery of a new technique to reform the surface of ceramic materials with laser-shock compression technology, a result which may contribute to the development of new materials. By irradiating the surface of zirconia (yttria-stabilized zirconia) with a high-intensity short-pulse laser, a multi-layered polycrystalline structure was formed on the material with a penetration depth of 130 microns.

Integrated In-line Metrology
Freiberg Instruments is now one of the world’s fastest growing, young and dynamic analytical instrumentation companies with products covering a broad spectrum of applications in fields/industries like Semiconductor, Microelectronics, Photovoltaic, Dosimetry, Medical Research, Luminescence Dating, X-ray diffraction, Material Research and Electron Spin Resonance.
Established in 2005 as an university spin off from TU Bergakademie – The University of Resources, Freiberg Instruments devoted the first few years to develop and test a whole family of fast, nondestructive, electrical characterization tools under production conditions, measuring parameters like minority carrier lifetime, photoconductivity and resistivity.
MDP Microwave-Detected Photoconductivity:
The advanced method MDP is well suited for both, defect investigation by e.g. injection dependent minority carrier lifetime measurements, as well as mapping of wafers or even ingots for inline metrology. MDP has a variety of advantages in sensitivity, speed and resolution.
MD-PICTS is a modification of MDP, where temperature dependent measurements of the defect part of the transient are accomplished. This allows to do a spatial resolved defect characterization.
What can be achieved with a flame photometer has been redefined by BWB Technologies.
