Electron Dynamics has revealed how it was able to solve a laser stability problem for a local opto-electronic company using its TC LV temperature control PCB.
The company was approached an opto-electronic company that had a problem with its laser stability being affected by the external instrument temperature.
Controlling the temperature of a device when the external temperature varies can prove a challenging problem.
Electron Dynamics's engineers looked into the problem and suggested that the laser area could be temperature-stabilised to improve this.
Electron Dynamics worked with the company to help it design the correct thermodynamics, and to interface the TC LV PCB into a current design.
Several units were produced and were used to test the performance and stability of the laser.
Currently, Electron Dynamics supplies this company with the TC LV controller, which provides this temperature control.
For more than five years, its product has benefited from the Electron Dynamics temperature control module as a 'bolt-on' building block.
With repeated buying and development, it is able to continue innovation through light, without the worry for electronic and temperature problems.
Electron Dynamics has also revealed how it was approached by a local branch of a multinational oil-testing consultancy, which was looking for a product that could provide the auto-titration tests it required.
It needed to be a portable instrument that can take samples of oil and analyse titration levels.
The consultancy has no requirement to get into any technical detail and the whole job from start to finish was outsourced.
It needed accurate measurement, full control of systems, and governing software that does its job.
Initially, Electron Dynamics investigated the customer requirements, test techniques and component performance required.
From this, it developed a proposal for the product, which used precise dosing pumps and fibre-optic probes to detect the changes in the oil.
Components were sourced, and the techniques developed and tested.
From this, two products were designed for different customer applications, which integrated all of the parts into each instrument.
Graphical software was developed for a PC to provide control and graphical display of the test information as the test progressed.
These products are available to the customer as an off-the-shelf product solution.
The client had specifically stated that it did not wish to take the technical development burden.
The service it provides now has a modern, high-precision product that is used worldwide and forms a fundamental part of its service, with return on investment occurring rapidly.
Electron Dynamics now has capabilities and IP developed for precision measurement, control and manipulation of materials and properties utilising light, liquids and temperature, and scope into other areas of control is possible.
Electron Dynamics has also described how it has helped a product manufacturer that wanted to provide laser alignment on its product.
Initially, the company discussed the customer's needs and proposed that the light beam was split off and quad detector PCB be mounted inside its product to detect the alignment.
From this, the mounting and physical aspects of the PCB were designed and agreed with the customer.
The electronics were also designed and provide four channels of output from the unit, showing the alignment of the laser.
The PCB was designed and prototypes made.
The performance of the product was tested by both Electron Dynamics and the customer.
Electron Dynamics was approached by a company that was developing a new electron microscope and needed additional resources to develop the firmware needed.
Working with the company's current hardware design, which consisted of a supervisory PCB and three slave units providing control functions, the unit needed to provide synchronised control actions as the process required.
Communication between the units was via RS232 and the firmware was written in C for PIC and dsPIC.
The units were designed and tested in-house and on-site with the customer, with improvements made as necessary.
Electron Dynamics has also detailed how it helped a company with a controller problem.
The company's existing controller was not adequate and did not have the drive nor the complex control required for its new Stirling engine.
Initially, Electron Dynamics reviewed the customer's requirements, and from this it produced an improved version defining the product.
Technology was also researched to look for up-to-date techniques and components for the high precision and drive required.
Two types of product were developed and prototypes produced.
These were evaluated and tested to all required specifications.
The products have now been available for more than five years and provide a good solution to the customer requirement.
Electron Dynamics helped a positioning company that needed an automatic and accurate three-axis measurement in less than one second.
Developed by Electron Dynamics, the unit provides three axes of automatic alignment to sub-micron accuracy, within one second.
The approach provided a number of alignment settings in a simplified way.
During the telecoms boom between the late 1990s and early 2000s there was more than 50 units sold worldwide, which provide Electron Dynamics and distributors with a high source of income.
Finally, Electron Dynamics has detailed how it developed an auto correllator for a university technique for analysing fast last pulses using a scanning Michelson interferometer.
Taking the original techniques, the mechanical and electronics designs were produced.
The product enclosure and package was developed together.
This resulted in a compact, easy-to-use package.
