Medical Technology
Medical technology can no longer do without high-quality CaF2 and MgF2 crystals
Health is our greatest asset. Industry and research are developing innovative medical technology that improves people’s lives. Our crystals are used in everything from diagnostic devices to therapeutic systems and help to recognise and treat diseases and improve patients’ quality of life.
Microscopy (CaF2)
Apochromats are optical systems, such as lenses or telescopes, which largely correct colour errors.
The word apochromat comes from the Greek and means “free of colours”.
How do apochromats work?
- Apochromats are refractors in which the lenses are arranged in such a way that at least three colours are combined in one focal point.
- This suppresses the chromatic aberration that is typical of refractor telescopes.
- Apochromats are a further development of achromats.
- Apochromats are usually optics with lenses made of three different types of glass.
- At least one of the glass types has a dispersion curve that deviates from the norm.
Where are apochromats used?
- Apochromats are the best choice for colour photomicrography with white light.
- Apochromats are also used in telescopes to avoid disturbing colour fringes on bright objects such as the moon or planets.
- Apochromats are also used in photographic machines.
