Скачать или смотреть Optical Quaility Inspection at Altechna

Altechna ensures high quality laser optics at its own in house metrology laboratory.
Visual inspection begins with optical surface quality inspection and visual examination according to Military and ISO surface quality standards.
We perform transmittance and reflectance measurement from 190-4900 nm from 0° to 75° angles.
Group delay dispersion could be measured from 500 to 1650nm in different configuration at angles from 0 to 70 degrees.
The laboratory carries out wavefront distortion measurements in reflectance and transmittance of flat and spherical surfaces per 100 mm diameter, software allows to perform diffraction and aberration analysis.
Altechna also executes effective focal length measurement from 5 mm to 5000 mm and radius of curvature measurement from 5 mm to 700 mm. Lens centration measurement unit is available with ‘Multilens’ software for multi lens system measurement and analysis.
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. Environmental chamber for temperature and humidity tests according to MIL requirements for optical coatings.
Each product is followed with inspection report.
