OST Photonics CdWO4 Scintillators(Cadmium Tungstate Scintillators)
CdWO4 Cadmium tungstate crystal is a high density, high atomic number scintillator with a relatively high light yield. The emission maximum is at 475nm and the total light output is 12 to 15 photons/keV. The light yield relative to NaI(Tl) on a bialkali PMT is 30 to 50%. In addition, CdWO4 Scintillator cadmium tungstate scintillator also has the advantages of strong radiation resistance and no radioactive background. The high light output and low afterglow make it ideal for use with silicon photodiodes in detectors for medical and industrial Computed Tomography (CT) scanners.
OST Photonics is able to supply CdWO4 crystals cadmium tungstate scintillator and CdWO4 linear or 2-D array upon your requests.

Li-6 lithium glass scintillator is a kind of inorganic scintillator which can be used for thermal neutron detection. It has the advantages of short decay time, high efficiency of slow neutron detection and good temperature performance. In addition, the Li-6 glass scintillator is easy to process and form, non-hygroscopic, acid and alkali resistant, can withstand the high and low temperature rapid change. Therefore, in the harsh situation that contains corrosive liquid and vapor, the lithium glass (Ce) can still work, but other scintillators cannot be suitable. Li-6 glass scintillator are widely used in neutron time-of-flight experiments, oil and natural gas exploration, moisture content measurement, nondestructive testing and neutron photography.

±-BBO (±-BaB2O4) is a negative uniaxial crystal which has large birefringence over a broad transparent range of 190nm to 3500nm. ±-BBO is an excellent crystal especially in UV and high power applications.
The physical, chemical, thermal, and optical properties of alpha-BBO crystal are similar to those of Beta-BBO. However, there is no second order nonlinear effect in alpha-BBO crystal due to the centrosymmetry in its crystal structure and thus it has no use for second order nonlinear optical processes. Instead, alpha BBO is widely used for fabrication of polarizers, polarizing beam displacers, phase retarders, birefringent plates, and time delay compensators especially those for UV and high power lasers.
Applications of ±-BBO Crystals
High power Beam displacers for isolators.
High power Polarizer
Time delay compensators
Advantages of ±-BBO Crystals
High UV transmittance
Large birefringence
High damage threshold

What is the Difference Between SAW Grade Material and Optical Grade Material?
Optical grade materials are materials with low strain and no impurities, they are grown from the best raw materials at a relatively slow growth rate, and are often used in optical applications where the highest quality is required. Optical grade wafers are widely used in optical devices and require excellent optical performance.
SAW grade materials are primarily used in non-optical applications, and their growth raw materials rank second only to optical grade growth raw materials. The growth rate of this material is faster than that of optical grade material, which benefits mass production and cost-effectiveness.
In general, these grades of wafers vary in material quality and use. Optical grade wafers are considered to be of the highest quality, while SAW grade wafers are relatively lower in price. The selection of the appropriate wafer grade is crucial, depending on the specific application and material quality requirements.
