Towards cleaner, more powerful, auto engines
To make cleaner, more powerful auto engines, a deeper understanding of fuel injection, mixing and combustion process is required: the VisiSizer is enabling fuel droplet size and velocity measurement
These are supplied in a stainless steel (316), 3mm diameter disk of 50 microns thickness with a centering accuracy of +/- 0.02mm (0.0008").
Custom made pinholes are just as easily available in materials such as alumina, copper, brass, molybdenum, tungsten, ceramics and polyimide as well as stainless steel.
In thin sheets pinholes as small as 3 microns are possible.

Precision flow devices, based on volumetric control of a liquid, gas or solid, such as in medical devices, face ever more stringent market demands.
Oxford Lasers micro-machining equipment answers the need for tighter and substantially smaller volumetric control by providing superior micro-hole drilling capability with tolerances of less than 1 micron.
Precision pinholes are important in a variety of applications including calibrated leak detection, optical and beam particle collimation and spatial filtering.
However, it is in the medical device market that they are most crucial.
Handheld nebulizers, variable-release medications and intravenous (I.V) regulators, flow meters and gas regulators, aerosol and oxygen face masks, disposable emergency oxygen resuscitators, disposable nebulizer products, apnea monitors and spirometer products are all examples of how this innovative technology can be used.
Leak testing is another area where the smallest possible holes are required in order to test packaging processes in the pharmaceutical industry.
Oxford Lasers can provide such artificial holes to simulate leaks in an automatic, production line, QC process or on a sub-contract batch basis.
For customers who are looking to out-source part of their manufacturing processes, Oxford Lasers' three on-site micro-machining applications laboratories offer direct access to the latest laser micro machining systems, including a new UV laser laboratory specially set up for work with polymers and glass.
A highly qualified and experienced team of application specialists is on site to carry out contracts or to advise.
Oxford Lasers applications facilities offer a high quality, reliable, development and manufacturing service with the production infrastructure and technical know-how to deliver products on time and in a cost-effective manner.
