23/06/2017 - LumOptica now offers COMSOL multi-physics modelling

To complement our expertise in optical modelling and simulation, we are pleased to announce the addition of COMSOL to our capability set. This is an extremely powerful software package for undertaking coupled, bi-directional multi-physics modelling based on finite element analysis. So, whether you’re interested in the propagation of lasers causing non-optical effects or vice versa (or both!), we can help.

20/01/2017 - Atmospheric Lens Concepts

BAE Systems PLC recently announced concept work it was undertaking which incorporated feasibility studies that LumOptica have undertaken around laser-atmosphere interactions to induce perturbations on EM waves. This is a fascinating subject area and one in which we were able to bring value-added expertise in high power lasers, optical design and technology intelligence. The full article can be seen here

28/09/2016 - Photonex 2016

Photonex 2016

We are excited to be exhibiting once again at Photonex, 12th & 13th October, Ricoh Arena, Coventry, UK. If you’re able, do come and see us at stand IL05.

Again, we will be giving a talk at the Photonex Innovation Live! meeting on Thursday 13th at 11:40…

Speckle – If you can’t use it can you lose it?

Speckle! Most of us in our industry would claim to be familiar with the phenomenon, at least to the extent that
we could qualitatively explain how it arises, and we’d also probably be aware that it can be usefully exploited
(as in a speckle pattern interferometer) but that it can also be a nuisance (e.g. in laser projection systems).
However, by its nature the treatment of speckle is mathematically complex and most of us would probably
be happy to confess to not understanding it in any detail. This talk will delve into the subject of speckle a little more deeply, avoiding the mathematics (mostly) but hopefully providing an illuminating insight into its properties. The talk will conclude with a look at some of the approaches that have been developed in order to reduce speckle in laser projection systems.

10/06/2016 - LumOptica to present at the 15th EOIR Conference, Shrivenham

Defence Academy
We are pleased to be presenting at the Electro-Optics and Infrared Conference, at the Defence Academy/Cranfield University, Shrivenham on 20th June 2016. We will present our latest developments in ultrabroadband multi-spectral beam combining.

Hope to see you there!

15/04/2016 - Happy Birthday to us!!

We are 1 today!

It felt appropriate that we were founded during the UN’s “International Year of Light” last year, albeit with slight apprehension! It’s been an exciting and profitable year and we’d like to take the opportunity to extend our deep gratitude to our customers, associates and well-wishers.

03/11/2015 - White Paper - Easy as ABC (...and D)

In modern times, the position of beam waists of Gaussian laser beams are readily found in optical design software packages but this gives no insight into why or how the beam waist finds itself in that position. This tutorial shows that a pair of equations can determine the position and size of a new beam waist if the position and size of an initial beam waist is known and there is an “ABCD” matrix representation of the optics following the initial beam waist….open here.

08/10/15 - Photonex 15

We are delighted to be exhibiting at Photonex, 14th-15th October, Ricoh Arena, Coventry, UK. Do come and meet us at stand IL04.

We will also be giving a talk at the Photonex Innovation Live! meeting on Thursday 15th at 11:20 in the Technology Theatre…

Techniques for laser beam combining (or how, in optics, you can indeed get a quart into a pint pot)

It is often the case that we need to combine two or more beams of light into one. For example: to combine the outputs from a number of low power lasers into a single more powerful beam; or to combine the outputs of different wavelength sources into a single multispectral beam. In the trivial case of a couple of beams a simple beamsplitter may suffice but there are limitations in this approach and it rapidly becomes impractical as the number of constituent beams increases. This talk will introduce some of the more novel approaches, illustrated with example systems, that have been developed to deal with the issues posed by the extremes of large beam counts, high powers and wide spectral range.
