We are offering scintillation detectors. Ce:yag is a fast scintillator with excellent mechanical and chemical resistance. Ce:yag scintillation detectors are preferred for electron microscopy, beta and x-ray counting, as well as for electron and x-ray imaging screens. The material�s mechanical properties enable production of thin screens down to 0.005mm thick. Does not degrade when bombarded by electrons or ions, thus making ce:yag suitable for high current operations. Light emission peaks at about 560nm (yellow) which means that an s20 photomultiplier is most suitable for detecting the emission. Response is better for ce:yag than for planotec p47 discs below 5kv and again at higher accelerating voltages over 100kv, where the performance of powder scintillators falls off while ce:yag response increases linearly. Although the signal from ce:yag and ce:yap is less than the p47, the sn ratio is better and therefore the final signal is better. Decay time approx. 60 nanoseconds. The side towards the light guide is micro-textured to increase light emission. Can be cleaned (polished) and recoated. Best to coat with 50nm al to avoid light sensitivity.

Tgg is an excellent magneto-optical crystal used in various faraday devices(polarizer and isolator) in the range of 400nm-1100nm, excluding 475-500nm advantages tgg has twice the verdet constant of a terbium-doped glass the thermal conductivity of crystalline tgg is an greater typical glass. Optical losses are lower for tgg than tb-doped glasses the combination of the above factors make tgg better suited to high average power applications. The principal limiting factor is thermally induced beam distortion. Beam distortion is less for tgg than tb-doped glasses under the same power loading level. Faraday polarizer is composed of the tgg crystal rod and a special designed magnet. The polarization of the beam through the magneto-optical materials deflexes and direction of the deflection only has some relations with the direction of magnetic field and has nothing to do with the direction of the beam propagation. Optical isolator is an optical component which allows the transmission of polarized light in only one direction.
