About Armstrong Optical
Founded in 1997, Armstrong Optical Ltd. is a specialist supplier of optical metrology instruments for both R&D and production. This includes interferometers for measuring shape, distance and thickness and instruments for MTF, optical centration, focal length and most optical parameters. In addition we supply chromatic confocal sensors and controllers and custom optical / mechanical assemblies. We are partners in the UK for Trioptics, SIOS, Precitec Optronik and Optical Perspective Group. (See all our Suppliers here).
Trioptics is the leading manufacturer of optical test equipment for research and production. This includes instruments to measure optical centration, lens thickness, precise angles, straightness, surface form, MTF and other optical parameters including alignment for wavelengths from the UV to the IR. In addition they manufacture precision electronic autocollimators for a range of applications and complete high performance systems for accurate turning of optical components and housings. Every step of the optical manufacturing process is covered including camera and electronics integration.
SIOS GmbH is world renowned for the development and manufacture of laser based interferometric precision metrological instrumentation. Their systems range from standalone measurement devices to complete measuring stations for measuring displacement, angles, weights, forces, pressures and vibration.
Precitec Optronik is the specialist for laser material processing and optical measuring technology. The wide range of CHRocodile sensors utilise several distinct techniques to perform high speed distance and thickness measurements. Chromatic confocal and interferometric methods are used to measure nearly all surfaces. Various white and infrared light sources are available to extend the ranges of materials that we can measure.
Optical Perspectives Group designs and manufactures Optical Alignment and Optical Inspection Instruments that make it easy to maximize the performance of optical systems.
We are happy to offer either individual systems or complete tailored solutions to specific requirements and welcome as much dialogue with our customers as possible. So please feel free to contact us at any time either by phone or email.
Our Primary Partners / Featured Products
Trioptics Featured Item – µPhase® 3.1/3.2/3.3.
Trioptics μPhase® interferometers offer objective and precise measurement results of surface and wavefront measurements – quickly and reliably. μPhase® interferometers are compact, small and lightweight digital tools which can be used in almost any working environment.

Trioptics Featured item – TriAngle Electronic Autocollimator Range
The TriAngle electronic autocollimators are non-contact optical test tools for the high-precision measurement of angular displacements of specular reflective surfaces and the accurate angular alignment of optical or mechanical parts. TriAngle autocollimators have a versatile modular design which allows them to be fitted with a wide selection of objective tubes, different sensors, reticles and light sources. With objective tubes of different focal lengths and apertures, the optimum measurement solution regarding angle resolution and measurement range is easily found.

Armstrong Optical have a TA 200-38 ex-demonstration system (with other accessories including a host PC, adjustable stand, etc.) available at an attractive price. If you are interested in purchasing this, please get in touch.
SIOS Featured Item – Triple beam laser interferometer
SP 5000 TR triple beam laser interferometers are precision length measuring instruments that combine three interferometers in one device. All three measuring channels are fed by one light source with the same highly stable laser frequency. Thus, three length values can be measured simultaneously with nanometer accuracy. From the difference between two length values and the calibrated beam distance, the corresponding angle can be determined with high resolution and high precision.

Featured Item – IRIS X-Series & IRIS Q-Series Range of IR Interferometers
The IRIS X-Series and IRIS Q-Series Range of Interferometers have been developed following a successful conclusion of drawing upon experience and expertise spanning over three decades in the design and supply of infrared interferometers. The designs have evolved during extensive hands-on experience of IR interferometry that include the practical measurement of wavefront aberration of thermal imaging lens and mirror systems, both afocal and focal systems, IR optical sub-systems and lenses, optical homogeneity of IR materials and flatness of optical surfaces.

Trioptics Featured item – OptiSurf® LTM
With the OptiSurf® LTM (Lens Thickness Measurement), TRIOPTICS offers a precise center thickness measurement system for single lenses and doublets that seamlessly integrates into any production process. The high precision low-coherence interferometry is based on the established OptiSurf® technology and measures single lenses and doubles with a glass thickness of up to 150 mm with a precision of ±0,5 µm. The non-contact measurement system is gentle on sensitive surfaces and coatings. In addition to the center thickness, the sag value can also be determined.

Trioptics Featured item – OptiCentric® 101
The OptiCentric® product group represents the global standard for optical centration testing and manual and automated cementing and bonding of lenses and lens assemblies. With its extremely high degree of centration accuracy and integrated operation, OptiCentric® systems are indispensable in modern optics productions. It makes no difference whether the sample has a small or very large diameter, works in the visual or infrared spectral range, or is to be cemented, bonded or just measured: modular OptiCentric® systems permit a wide range of different applications and samples for optimum composition. With its especially stable structure and an increase in processing speed by the factor of 4, the OptiCentric® 101 is increasing precision and efficiency.

Precitec Featured Item – CHRocodile C
The image on the right shows the C on a custom stand from Armstrong Optical, measuring the thickness of a glass wafer.
The ultra-compact CHRocodile C is the ideal device for high-precision distance and thickness measurements. The combination of optoelectronic and optical probe in a single housing not only saves space but also offers great value for money. CHRocodile C is the alternative to classical laser triangulation sensors.
With its robust, compact and easily integrable design, the CHRocodile C is the ideal device for high-precision distance and thickness measurements in any industrial inline or offline application.
An ultra-high dynamic range and outstanding signal-to-noise ratio ensure optimal measurements on any kind of surface. The coaxial measurement ensures no shadowing. Hence, the CHRocodile C is a compact and economical replacement for laser triangulation sensors. Thanks to interchangeable optical probes the CHRocodile C can be adapted to any measurement task.
The CHRocodile C HS has a larger beam spot and is specially designed for high-intensity measurements on dark surfaces

Optical Perspective Groups Featured Item – Point Source Microscope (PSM)
The Point Source Microscope enables optical alignment by detecting and locating optical features on the micrometer level and then relating them to mechanical fixtures, datums and features such as steel balls.
The PSM is also valuable for aligning aspheres and off-axis aspheres by using the aberrations aspheres produce when they are misaligned.
In addition to its use for alignment, the PSM is useful for incoming inspection for radius of curvature, focal length, figure errors larger than 8th wave and centring errors.
