Stainless Steel Chamber Shield Shutters

noreply@blogger.com (searchfirst) — Thu, 07 Aug 2008 15:33:00 +0000

Perhaps stainless steel chamber shield shutters don't come up in everyday conversation; but if you work for us at Highland Scientific then actually that might not be true. Not that we all walk around speaking in an engineering version of "tongues" (a religious reference FYI) but, as with many niche businesses, there is a tendency to exclude those not in the know by using terminology such as this. Feel free to take a look at our catalogue; the chances of you finding this page by chance are fairly slim.

Dense Wavelength Division Multiplex Scanners

noreply@blogger.com (searchfirst) — Fri, 25 Jul 2008 10:43:00 +0000

Dense wavelength division multiplex scanners are used in fibre-optic communications to convert multiple optical carrier signals into a single fibre. This effect is produced by making use of varying wavelengths of laser light to carry the different signals. The net effect of this is that it becomes possible to increase the capacity of communication, whilst also enabling communication in two directions.

If you're looking for spare parts for dense wavelength division multiplex scanners then we'll have what you're looking for. See the stock catalogue for more details.

Please browse our extensive catalogue for more details and for current stock. Please don't hesitate to contact us if you don't see what you are after as we may be able to source it for you.

Electron Beam Guns

noreply@blogger.com (searchfirst) — Fri, 25 Jul 2008 09:10:00 +0000

In general an electron beam gun is found most often in monitors and televisions using cathode ray technology. There are several classes of gun which are divided by the number of electrodes, whether they use magnetic field or electrostatic focusing, by the mechanism of emission and by the field of electric generation type.

We have many different types of electron beam gun parts available through our web site at Highland Scientific. As spare parts suppliers we have a continually rolling stock supply of components which can be used in the assembly of the gun.

In a television the cathode ray tubes are made up of three electron guns, with each being responsible for a different colour stream. The picture displayed by the combination of electron beam guns looks to the human eye as a multi-coloured moving image, but in actuality the image is produced by just three colours; red, green and blue.

If you want electron beam gun components please feel free to take a look around the rest of the web site.

Planetary Calotte Substrate Rotation Systems

noreply@blogger.com (searchfirst) — Mon, 14 Apr 2008 15:46:00 +0000

Highland Scientific stock components for the optical and opthalmic industries supplying customers in various different industry sectors. Part of their stock list includes components which are used in planetary calotte substrate rotation systems.

These rotation systems are used in optics, more specifically in coating chambers. A coating chamber is made up of several components, which form to produce subsystems within the chamber. The first section of the chamber holds the component, rotating it during the coating process. There are two options when it comes to the rotation system; planetary dual rotation or calotte single rotation.

It is generally accepted that in cases where precision and consistency are crucial to the end result, planetary rotation systems are considered the optimal choice; whereas calotte systems are used if there is more room for manoeuvre. This latter method produces more parts per run.

For more details on planetary calotte substrate rotation systems and the various components in stock please visit the main Highland Scientific website.

High Vacuum Systems Construction Items

noreply@blogger.com (searchfirst) — Wed, 12 Mar 2008 14:44:00 +0000

A perfect vacuum is defined as a volume of space empty of all matter, something which is impossible to achieve in practice. As this is the ultimate definition of a vacuum the quality of any one particular vacuum is determined by it's gaseous pressure. The pressure in a perfect vacuum would be absolute zero, so the lower the pressure the higher the quality of vacuum.

The quality of a vacuum can be divided into different classifications, as follows: Atmospheric pressure, low vacuum, medium vacuum, high vacuum, ultra high vacuum, extremely high vacuum, outer space, perfect vacuum. Highland Scientific stock construction items for the creation of high vacuum systems.

High vacuum systems are characterised by the mean free path (MFP) of it's residual gases being longer than the size of the chamber or object under testing. It generally needs pumping on a multi-stage level and ion gauge measurement. It can sometimes be differentiated between high vacuum and very high vacuum systems.

Fast Pumping Cryogenic Meissner Coils

noreply@blogger.com (searchfirst) — Thu, 31 Jan 2008 16:18:00 +0000

Fast pumping cryogenic meissner coils is a fast cycle cryopump which is connected to a refrigerant source and then extended through a pass-through opening of a vacuum chamber. The head section of the coil contains a feed tube, which connects to a valve, for the reception of either a cold or a hot refrigerant during the various sections of the machine operation.

With the fast pumping cryogenic meissner coils there is also a flexible probe section connected to the rigid head end. This probe can be customised into different shapes in order to assume different configurations in the vacuum chamber. Connected to this probe is a flexible tube for feeding the refrigerants through the head section and outward to the end of the probe section, whilst an outer membrane to this feed tube allows the return of the refrigerants along the probe section through the head section.

If cold refrigerant was to flow through the flexible probe section during a vacuum cycle it would allow the condensing of water vapour onto it's surface, later on during the cycle hot refrigerant flows through the probe and this condensed water vapour is released to the immediate environment.

Highland Scientific supply a whole range of stock components including fast pumping cryogenic meissner coils. Please have a look through our product pages for more detail on our stock of spare parts.

Spare Parts Suppliers

Welcome to the blog pages for Highland Scientific. Over the coming weeks and months I will be updating these pages with news and articles based on the spare parts industry. For the first blog post I thought I'd just write a little introduction to the company and let you know something of what we do and the services we provide as spare parts suppliers.

The main thrust of our business is aimed at being spare parts suppliers to the semiconductor, optical and opthalmic industries we have also provided products to a huge range of different sectors. Our perpetually evolving stock of both pre-owned and new spare parts is sourced from global leaders in their field.

We are spare parts suppliers of such things as vacuum coating system components and supply stock components from Applied Materials, ASM, Balzers, ESEC, Firfax, Swiss Step and Tokyo Electron.

Our website is host to a plethora of spare parts and as suppliers we believe we have one of the most extensive online catalogues on the internet. Please feel free to browse through the product pages as you are sure to find the right components for your requirements.
