  • UV vacuum Calcium Fluoride
    UV vacuum Calcium Fluoride

    It should be used in the wavelength range 130-200NM, sometimes up to 110NM.

    The material is mostly used in UV spectral analysis and in KF/CF vacuum windows, requiring high transmittance and good irradiation resistance below 200NM.

    Vacuum grade calcium fluoride requires high purity of the raw material and control of the mixing of other elements in the crystal growth process, and try to improve the transmittance below 200 NM.

  • Excimer Calcium Fluoride
    Excimer Calcium Fluoride

    for use on lasers in the 193/248/366NM wavelength band.

    Can be used as a laser light source, lighting equipment and imaging equipment, where the light source requirements mainly require high internal transmittance, no colour core, laser damage threshold to be good, so that the life of the light source can be greatly extended; laser external light path system on the material uniformity and consistency requirements are higher, at the same time because of the ultra-precision characteristics of the workpiece, the material often requires precision annealing, all the excimer grade materials are All excimer grade materials are custom-made products, which are the high-end products in calcium fluoride materials.

    Calcium fluoride belongs to the cubic crystal system of the high-grade crystal family and is typically isotropic.

    However, this is often only theoretical. In practical applications in complex and high-precision optoelectronic systems or for high-power laser purposes,

    or in applications such as gyroscopes and high-precision microscope lenses, calcium fluoride in specific orientations is often the preferred solution for optical designers and applicators,

    based on the nuances of the material and the cumulative errors in material processing.

  • UV Calcium Fluoride
    UV Calcium Fluoride

    Typical spectral characteristics are 205NM and 306NM with no significant absorption, and the requirement for no reduction in infrared transmission. UV single crystals are mostly used in day-blind detectors 260-280NM or for UV imaging to eliminate chromatic aberrations, resulting in lower noise and better image quality. They are also partially used in UV vacuum observation windows or for spectral analysis. UV materials are mostly high purity chemical synthetics and require controlled absorption of cerium and lead in the crystal growth and must comply with ROHS & REACH standards. There are, of course, some natural ore materials that are screened later to meet the requirements, but because the consistency and stability of the material is not guaranteed, natural materials are generally not recommended.

  • Infrared polycrystalline Calcium Fluoride
    Infrared polycrystalline Calcium Fluoride

    IR polycrystalline, a structure with multiple crystals applied beyond 400 NM.

    The typical characteristic is the presence of distinct grain boundaries, the number of grain boundaries is greater than one, mostly between two and four, and the number is not controllable.

    The permeability of polycrystals is the same as that of single crystals, the chemical properties are the same and the physical mechanical properties are not significantly different from those of single crystals, but the optical delay properties are not as good as those of single crystals.

    Because of the homogeneous properties of calcium fluoride and the high yield and low price of polycrystals, they can be used for protective windows, single lenses or single prisms, but for high power laser applications or for lenses in a set, single crystals are often recommended.

  • Zirconia Oxygen Analyzer
    Zirconia Oxygen Analyzer

    BZ series zirconia oxygen analyzer is mainly composed of two parts: “BZ-S probe” and “BZ-W transmitter”.

    1.BZ-S probe: It is an oxygen sensor equipped with zirconium oxide battery, whose main function is to measure the oxygen content in flue gas in real time and output the corresponding oxygen potential signal data.

    2.BZ-W type transmitter: one is to control the working temperature of the thermostat at the front of the probe; the other is to convert the potential signal value output from the probe into the corresponding oxygen value, and convert the oxygen value into the corresponding current value output or digital signal for transmission.
