Altechna sign distribution agreement with Aerotech

Altechna has strengthened its links with Aerotech, signing a distribution agreement that will add Aerotech's micropositioning mechanics and motion controls to the Altechna product line.
Aerotech already works closely with Altechna R&D Ltd., branded as the Workshop of Photonics^®, providing nanometre level positioning sub-systems for application customised 2D and 3D laser micromachining centres used across industry and research.
The agreement covers Aerotech's complete product range from single motion components such as linear motors and individual positioning stages through to high performance sub-assemblies and custom designed motion sub-systems. The agreement also ensures that the technical sales and support staff in Vilnius receive in-depth product training and fast track support for its customers in industry and academia.
"We are very excited with the new distribution agreement," says Tadas Lipinskas, Director of Altechna Co Ltd., "having worked with Aerotech on many important projects, integrating their micropositioning and motion controls into our laser micromachining systems, we are very confident that the range will add real value for our customers."

Test your damage threshold

Altechna offers various metallic and dielectric coatings made by e-beam deposition (EBD), IAD, IBS coating techniques. All new coatings are being tested for LIDT performance in metrology laboratory.

One of the biggest concern while choosing coatings from a new supplier is the LIDT value warranty which is the most important for your experiment success and final device reliability. Altechna has all necessary equipment, qualified staff experience and know-how in LIDT tests. All measurements for "1 on 1" and "S on 1" procedures are performed according to ISO standards: ISO 11254-1 and ISO 11254-2 respectively.

Following options are available:
• 1064, 532, 353 nm, 3-5 ns, 1-10 Hz
• 1030, 515, 343 nm, 200-400 fs, 1 kHz – 200 kHz

With LIDT measurement results we provide detailed test report with characteristic damage curves and damaged spot pictures:

New Daughter Company

Altechna Co. Ltd. has separated its R&D department into a separate legal entity – Altechna R&D Ltd., 100 % owned by Altechna Co. Ltd. This mature decision was made seeking to establish an independent company for commercialization of in-house developments, utilizing its own and partners‘ intellectual property.

Key areas of practice:

• Femtosecond laser micromachining;
• Tools and parts for laser machining systems;
• DPSS micro lasers and control electronics;
• Laser system control software.

Having a wide range of products and technologies, the company intends to launch a 589 nm laser, several solutions for laser control electronics and new releases of 3D laser system control/automation software packages – all within next year.
The new company operates under the trademark Workshop of Photonics, while the legal name is Altechna R&D Ltd. showing relation to the parent company.

Altechna awarded in Swedish Business Awards

In "Swedish Business Awards 2011" Altechna company group received Most Sustainable Growth award.
Altechna was granted with this ward for its good financial results, increasing the number of employees and participation in the international market. By developing laser technology based environmentally friendly solar panel production Altechna promotes scientific and business cooperation.
In 2008 Altechna has started research and development in solar energy sector and by now has developed a unique femtosecond laser technology for efficient and environment friendly solar cell production. In 2010 as a result the first industrial-research laser workstation for c-Si solar cells SOLLAS was designed.

Z Polarizer: a Unique Converter Presents New Advantages

Workshop of Photonics (WOP) together with prof. Peter G. Kazansky’s group from Optoelectronics Research Centre (ORC) at the University of Southampton developed a direct laser writing technique for the production of radial polarization converters also known as Z polarizers.

Such radial polarizers would be mainly applied at laser machining, microscopy, optical tweezers as well as Raman spectroscopy systems. Our Z polarizers have distinguishing features: they are resistant against high-power laser radiation due to monolithic fused silica window design; anti-reflection (AR) coatings can be applied; and a single element is used both for polarization conversion and generation of higher topological charge optical vortices.



WOP's and ORC's laboratories expect to prove significant advantages of Z polarizers in laser micromachining, such as decreased spot size and uniformity of light-material interaction regardless of machining direction.


Being a commercialization partner Workshop of Photonics is also looking for integrators and end-users in the fields of laser machining, microscopy and optical tweezers. Testing units are already available, while small scale production of the Z polarizer devices is planned for the middle of autumn. Custom development of machining heads and optical assemblies incorporating radial polarizers is possible upon request.

The University of Southampton has already applied for a patent application and has appointed Altechna R&D Ltd. an exclusive commercialization partner.
