Category:

Description

CaF2 | Infrared Crystal is a crystal with good transmission from 0.15μm to 9μm. It has a low refractive index, is slightly soluble in water, and is sensitive to thermal shock.CaF2 is commonly used as window material for both infrared and ultraviolet wavelengths without an anti-reflection coating. It is vulnerable in atmospheric moisture at 600°C, where it begins to soften and the maximum temperature is 800°C, when moisture is not present. In addition, the irradiation of Calcium Fluoride windows causes some loss in UV transmission.

CaF2(Eu) | Scintillation Crystal is a scintillator with stable chemical and physical properties capable of charged particle, low gamma ray, and beta ray detection.

SKU: SCN-CAF-EU Category:

Description

CaF2(Eu) | Scintillation Crystal is a scintillator with stable chemical and physical properties capable of charged particle, low gamma ray, and beta ray detection.

CaF2(Eu) | Scintillation Crystal is a scintillation material that has the advantages of being non-hygroscopic and relatively chemically inert. Typically, CaF2(Eu) is used for detection of beta rays due to its relatively small backscattering, though it can also be used for detection of charged particles and soft gamma rays up to several hundred keV. However, it is not suitable for detection of high-energy gamma rays because of its small photofraction.

CdWO₄ | Scintillation Crystal

Request quote

CdWO4 | Scintillation Crystal is a scintillator with high density, virtually no afterglow, and relatively high light yield, perfect for detecting gamma rays and high-energy X-rays.

SKU: SCN-CDWO Category:

Description

CdWO4 | Scintillation Crystal is a scintillator with high density, virtually no afterglow, and relatively high light yield, perfect for detecting gamma rays and high-energy X-rays.

Cadmium tungstate (CdWO4) is a scintillation crystal most promising for spectrometry and radiometry of radionuclides under extremely low activities because of its low afterglow and sufficiently high light yield. The crystal is transparent and emits light when hit by gamma and X-rays, making it useful as a detector of ionizing radiation. It has relatively high light yield; its light ouput is about 40% of NaI(Tl), but the time of scintillation is quite long (12–15 µs). CdWO4 is often used in computed tomography (CT).

Co2+ MgAlO4 | Q-Switch Crystal

Request quote

Co2+MgAlO4 | Q-Switch Crystal is a relatively new material for passive Q-switching in lasers emitting from 1.2~1.6um, in particular.

Category:

Description

Co2+MgAlO4 | Q-Switch Crystal is a relatively new material for passive Q-switching in lasers emitting from 1.2 to 1.6um, in particular. For eye-safe 1.54um Glass(Er) laser, Co2+MgAlO4 also works at 1.44um and 1.34um wavelengths. The high-absorption cross section of 3.5 x 10-19cm2 permits Q-switching of Glass(Er) lasers without intracavitary, focusing both with flash-lamp and diode-laser pumping. Negligible excited-state absorption results in high contrast of the Q-switch, i.e., the ratio of initial and saturated absorption signals is higher than 10. The crystal’s excellent optical, mechanical, and thermal properties give an opportunity to design compact and reliable laser sources with this passive Q-switch.

 

ADVANTAGES

  • High optical quality
  • Uniform co-distribution
  • High-absorption cross section
  • Negligible excited-state absorption

 

MAIN APPLICATIONS

  • Passive Q-switch materials for solid state lasers (1540nm eye safe lasers)
