Aprašymas Savybės Metrology

Altechna Co. Ltd. supplies high quality standard and custom-made interference filters within the spectral range from 250 nm to 5000 nm. We also can offer biomedical bandpass filters, which are specially designed for biomedical instrumentation, including chemistry analyzers and microplate readers. These bandpass filters include standard or custom matched filters. Fluorescence filters, which we can supply includes such features as steep slopes, deep blocking (up to OD 6), minimal spectral crosstalk, high transmission and environmental durability.

In general interference filters are used as wavelength selectors in astrophysics, clinical chemistry, material analysis, quality control, and in gener

Altechna metrology lab applies following product inspection:

Visual inspection – surface quality evaluation according to MIL 13830 and ISO 10110 standards

Dimensions – measurement of geometrical dimensions, as diameter, thickness, etc.

Transmittance (Spectrophotometer, laser)*

Flatness (Interferometer)

Wavefront distortion (Interferometer)

Parallelism (Goniometer, interferometer)

*(…) used equipment
