Metrology - Optical Quality Inspection at Altechna

Optical elements are widely used in various fields of application – from single element in simple optical system to very complex industrial systems, where every parameter of each element is critical to overall system reliability and performance. Altechna is concerned about your success in experiments and final product performance, therefore in cooperation with Vilnius University we are performing following test procedures:

• Optical surface quality measurements;
• Transmittance and reflectance measurement in 190-1100 nm range;
• Surface flatness, wavefront distortion measurements of flat and spherical optics;
• Angle measurements for prisms, wedges and other optics;
• Non-contact ROC, Focal length measurements;
• Custom made tests.

Also we offer:
• Laser Induced Damage Threshold (LIDT) tests for wide range of laser wavelengths. Tests are performed with cooperation with Lidaris;
• Optical absorption tests according to ISO 11551 standard;
• Total scattering measurements;
• Transmittance measurements from 190 nm to 20000 nm.

For measurements we apply:
• Stereo and analytical microscopes;
• Spectrophotometer;
• Interferometer;
• Goniometer;
• Spherometer;
• DPSS CW lasers (405, 532, 632, 800, 1030, 1064)
• Femtosecond laser Pharos with harmonic module Hiro (Light Conversion).
