Coating technologies at Altechna
Our coatings cover wavelength range from deep UV (193 nm) to far IR (25 µm) with biggest part of coatings done in wavelength ranges of most conventionally accessible laser and illumination sources from 266 nm to 2 µm.
We offer a set of standard and custom coatings per individual request:
- Anti-reflection coatings
- High reflection coatings
- Beam splitter coatings
- Partially reflective coatings
- Polarizer coatings
- Filter coatings
- Ultrafast GDD compensated coatings
- Gires-Tournois interferometer mirrors (GTI)
- Variable reflectivity mirrors
- Metallic coatings
Each coating is special and over the years in the photonics field we have learned that flexibility is the key to meet high demands of our customers therefore our coatings are done using different technologies which are chosen for separate coatings individually. Here is our list of coating technologies available at Altechna:
- Electron beam evaporation
- Ion assisted deposition
- Ion beam sputtering
Each technology is different and is used according to requirements of spectral sensitivity, damage threshold, hardness, surface quality etc.
Best optical quality inspection practise at Altechna
Visual inspection begins with optical surface quality inspection and visual examination according to Military 13830 and ISO 10110 standards.
Altechna also executes effective focal length measurement from 5 mm to 5000 mm and radius of curvature measurement from 7 mm to 700 mm. Lens centration measurement unit is available with 'Multilens' software for multi lens system measurement and analysis.
We perform transmittance from 190-1100 nm and reflectance measurement at 0° and 45° angles.
The laboratory carries out wavefront distortion measurements diffraction and aberration analysis surface figure of flat and spherical surfaces per 100 mm diameter.
Moreover we offer: angle measurements of various elements with 0,4 arcsec accuracy; waveplates retardation measurement using Soleil-Babinet Compensator, Axicons Bessel beam generation measurement.
Each product is followed with detailed quality report. For more information please visit www.altechna.com.
Altechna to Represent Lithuania in Europe’s Business Awards
The judges of European Business Awards have selected organisations to represent Lithuania who exhibited the highest levels of innovation, business excellence and sustainability.
Adrian Tripp, CEO of the European Business Awards says, “Over the past seven years we’ve received an incredibly high standard of entries from organisations that are passionate about their business. However, very few get the chance to fly the flag for their country and compete across Europe to be recognised as one of Europe’s finest. It really is an exceptional accolade to be picked as a National Champion and we’re looking forward to seeing Lithuania in the next round.”
“At Altechna we’re absolutely thrilled to be selected to represent Lithuania. We’ve been operating for over seventeen years in the laser technology scetor and it’s an honour to be recognised as one of the leading organisations in our country and in our field. We’re looking forward to the next round of the competition,” says Altechna director Tadas Lipinskas.
Altechna expands laser technology company group
By this investment Altechna is seeking to extend manufacturing capabilities, to ensure the production of unique laser optical components with dielectric coatings within the company group and pay special attention to quality control. Also company plans to design and develop new products and invest in update of technical facilities.
Altechna has been operating in the laser industry since 1996. Currently company has nearly 40 employees. Almost all employees have academic backgrounds in physics. The Company operates in three main areas: supplying general optics, optoelectronics and laser related products, designing of optomechanical assemblies, and providing innovative solutions for academic and industrial customers.
Optida is the largest optical coating company in Lithuania. It manufactures optical coatings and delivers services in optical technology field. Company is developing and manufacturing optical components for lasers, laser systems and optical devices. Within company developed optical coating technologies enables to manufacture optical elements corresponding international standards.
Another member of Altechna company group is UAB Altechna R&D, internationally known as Workshop of Photonics®. It is involved in the development and commercialization of instruments and solutions for laser micromachining tasks for both industrial and academic customers.
Altechna group is owned by individual persons and growth capital fund LitCapital I. LitCapital I acquired a minority stake in the company in 2013 and provided the company with resources required for rapid growth. LitCapital is a EUR 25 million size growth capital fund incorporated in Lithuania. LitCapital I fund was established under the JEREMIE initiative in cooperation with European Investment Fund (EIF) and is aimed at investing into the expansion of private Lithuanian companies.
