Different with normal pigments, fluorescent pigments can absorb part of the light (including UV light) and transfer it into a longer wavelength and similar to the normal reflected hue light -- fluorescent light which makes this pigment exceptionally bright and of outstanding visibility.Â
Fluorescent pigments can be divided into thermoplastic, solvent-based, water-soluble three series.

Magnesium Fluoride (MgF2) Windows offer excellent broadband transmission from the deep-UV to the mid-infrared.
MgF2 is a rugged material resistant to chemical etching, laser damage, and mechanical and thermal shock.
MgF2 exhibits excellent broadband transmission from 120 nm to 8 μm , from the deep UV to the mid infrared. This makes them a good choice for UV radiation sources and receivers as well as for use at the Hydrogen Lyman-alpha line. They are often used as UV viewpoints, and are a good option for UV polarizers and excimer laser applications. It has a high transmittance between 120 nm and 8 µm, and between 0.4-5.0 µm transmits over 90%.
MgF2 has a melting point of 1255 degrees Celsius. It has a density of 3.177 g/cm3, and a tetragonal crystal type. Our optical windows are typically oriented with the round surfaces perpendicular to the c-axis of the MgF2 crystal to minimize birefringence. Custom random cut MgF2 windows can be manufactured on request.
MgF2 is the only optical material which combines a wide spectral transmission band with birefringence. This birefringence means that the refractive index depends on the polarization and propagation direction of light. Because of birefringence, a MgF2 window can exhibit double refraction, so that a ray of light will be split by polarization into two rays with different paths.
- Excellent Transmission from 120nm to 7μm
- Rugged and Durable
- Resistant to Chemical Etching
