Optical Surfaces Ltd. announce a new series of high-performance beam collimators designed for Modulation Transfer Function (MTF) testing of optical systems.

Benefiting from a lightweight design and new assembly technique – the LW-series of beam collimators uniquely combine high stability, high performance and short delivery time all at a market competitive price.

LW-series beam collimators incorporate a low expansion off-axis parabolic mirror, manufactured to better than lambda/10 p-v surface accuracy. The optics within the beam collimator, are secured by the use of stress-free mounts and come pre-aligned for optimum performance. The off-axis design of LW-series beam collimators produces no central obscuration thereby ensuring highly efficient transmission is obtained.

The all-reflecting design of LW-series beam collimators is achromatic and with aluminium / magnesium fluoride coatings can operate from the UV to the infrared without adjustment. Using low expansion glass mirror substrates these beam collimators provide high operational stability and performance. Each system has an output port datum plane giving a defined distance to the focus. Each system is also supplied with an easy-to-use alignment aid to identify the centre of the focal plane. All LW-series beam collimators provide a 20mm field ensuring full compatibility with standard black bodies.

For further information on the LW-series of beam collimators for MTF optical testing please contact Optical Surfaces Ltd. on +44-208-668-6126 / sales@optisurf.com.

Optical Surfaces Ltd. has been producing optical components and systems for leading high-power laser research groups for many years. The company’s ISO 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in solid chalk where temperature remains constant and vibration is practically non-existent. With such stable conditions testing, particularly with long path lengths, becomes quantifiable and reliable. Working with these natural advantages is a highly skilled team of craftsmen with a commitment to excellence in both product quality and customer service.

Titan Enterprises

With more than 40 years’ experience in flowmeter innovation — Titan Enterprises Ltd is a UK-based manufacturer of high-performance solutions such as the Atrato ultrasonic flowmeter, oval gear flowmeters and the low flow turbine flowmeters and instrument range. Our knowledgable team can offer either an off-the-shelf meter or fully bespoke flow system designed for a particular application, whether it is a low-cost OEM solution or a specialist flowmeter in exotic materials you are looking for.

Titan’s company philosophy of ‘pushing the envelope by trying to do things a little different and better’ has resulted in sales of more than 500,000 products in 50 countries worldwide and a repeat purchase percentage of 95 per cent — something that founder Trevor Forster is justly proud of.

Today, Titan supplies innovative flow measurement solutions to a broad range of sectors, including medical, industrial, food and drink, laboratory and pharmaceutical. Its latest innovation — the Atrato flowmeter range — is set to challenge conventional flowmeter thinking the world over. The culmination of eight years’ research and development in collaboration with the Department of Process & Engineering at Cranfield University (UK), it can handle low flows from laminar to turbulent and is largely immune from viscosity effects.

For higher-volume users we can tailor the design of a flowmeter to match your exact application requirements and thus not compromise achievable results with a less-than-ideal sensor. The resultant device would be unique to your application but would still benefit from Titan’s tried-and-tested, modern manufacturing methods to ensure a competitive OEM solution. From an initial concept Titan can offer a complete service from budget costings through prototypes to full production. Often the cost of origination and tooling can be amortised over the life of the product.

All flowmeters produced by Titan are designed and manufactured to ISO9001 and calibrated to an uncertainty of ±0.25 per cent. We produce chemically resistant, high-accuracy digital flowmeters that are not only competitively priced but are engineered to give long-term reliable performance.

However, the value of a flowmeter cannot be judged by price alone. Often in industrial applications the reliability of a product far outweighs the initial purchase price as ‘downtime’ is extremely expensive. At Titan, we endeavour to produce devices that are inherently reliable but are manufactured using the latest and most economical production techniques.
