The PSM makes optical system alignment easy, fast and deterministic. Use the PSM to align each optical component’s centers of curvature of its theoretical design location to within 1 μm laterally and 3 μm axially.
Align to actual optical datums such as centers of curvature and foci rather than relying on proxy mechanical features. Then mechanical tolerances can be relaxed to reduce the costs of optics and mounts.


The PSM is invaluable for aligning aspheric optics including free forms. The PSM locates reflected images and shows the point spread as in a Star test. By adjusting the asphere in tilt and decenter while keeping the image centered on the PSM, the aberrations in the image are eliminated showing the asphere axis is aligned to the system axis.
Because the PSM is sensitive to image shape, or point spread, to a level of about λ/8, the PSM can detect errors in individual components while they are being assembled. Corrections for out of spec components are made prior to complete assembly saving time and money.
Another use for the PSM is measurement of radius of curvature providing as easy check on whether an element has been inserted backwards. By removing the objective the PSM becomes an autocollimator with sub-second sensitivity for angular alignment.


The PSM comes complete with a 10x objective, laptop and NI LabView based PSM Align software for use anywhere in your shop or test setup. In addition to the autocollimation mode an internal LED Kohler illumination system makes the PSM into a full field digital microscope.
A range of objectives and mounting hardware make it easy to tailor the PSM to applications throughout your shop or laboratory.

InfraTec ImageIR 9300Z long range surveillance camera system


IIR9300Z_thumb Church_of_Our_Lady_Dresden_1 … from 1x (28mm) to Church_of_Our_Lady_Dresden_630x (850mm) with continuous zoom in about 3s






With the capability to be easily integrated into existing CCTV and surveillance networks the new ImageIR 9300Z imager is based around a high performance indium antimonide snapshot detector that can deliver 1280×1024 pixel resolution at 100 frames per second.


This means that even transient events can be captured at long range – vehicle detection in all weathers at any time of day or night at ranges beyond 18,000m.


To see the imaging capabilities of the ImageIR 9300Z on the skyline of Dresden in Germany please click on this link: ImageIR 9300Z video clip


If you’d like more details or a demo of this remarkable imager please do not delay, call us on +44 (0) 1604 654 220 today.

SIOS Long Range 3 beam interferometerSIOS GmbH Long range interferometer – 3 beams

The SIOS GmbH SP-LR  long range 3 beam interferometer, offers high precision triple beam displacement and angular measurement over 15 m, and is based on the popular SIOS GmbH SP series of triple beam laser interferometers.

The measuring reflector is based on a combination of hollow reflectors allowing for a maximum tilting angle of ± 5° when the center of rotation is in the center of the reflector.

For demonstrations call Armstrong Optical (44 (0)1604 654220) or CLICK HERE.

For more information please download the lastest flyer. SIOS SP15000TR PDF to view more the SIOS product range or more SIOS displacement products. For single beam long range measurements please view the SP-LR and for short range triple beam measurements the standard SP-TR.

Contact Centre Thickness Measurement

Contact Centre Thickness Measurement CT Guage

The Contact CT Gauge from Armstrong Optical offers thickness measurements of up to 100mm with a standard diameter range of up to 300mm.

Used for quick, accurate centre thickness measurement of glass components, this system incorporates two Heidenhain linear probe gauges mounted in opposition. The gauges are linked to a digital display which shows the position difference between the probe tips thus giving a direct reading of centre thickness.

The top gauge has a range of 25mm, resolution of 0.1μm and is movable to give access for thicker lenses. The bottom gauge has a range of 12mm, resolution of 0.1μm and is generally fixed. Both gauges have probe-lifters so that the probes may be retracted allowing easy access for positioning of the lens prior to measurement.

The table, mounted between the gauges, is constructed from TUFSET plastic on an aluminium backing plate, offering robust construction along with a non-marking surface.

The complete system is mounted on a granite base offering stability with low maintenance (corrosion free).
