LDC-X200 Laser Diameter Measurement System Overview The non-contact diameter measuring system, is mainly used in the measurement of the outer diameter of various wire rods, bars, wires and pipes. The system can detect the change of the diameter (outer diameter) of the measured object in real time under the high temperature state. The working principle The diameter measuring system takes the laser scanning method as an example. It adopts the probe imported from Japan, which can achieve an accuracy of plus or minus 2 microns in the range of 0.3 to 30 mm. The acquisition frequency reaches 2000 times/second. The probe uses a self-excited infrared light source, which overcomes the measurement problem in dim environments. It adopts the measurement method of pulse parallel light scanning, and has a strong ability to resist the jitter of the measured object. (As shown in Figure 1) Since the shaking frequency of the measured object is much smaller than the scanning frequency, when the measured object A moves in the shakeable area, the measurement result will be able to ensure its accuracy because the time it blocks the beam does not change. Figure 1: Probe Scanning Radiation Area The detection principle is as follows Figure 2: Working Principle First, the crystal oscillator generates self-excited high-frequency pulses, which are sent to the comparator and the stepping servo motor respectively. The stepping servo motor drives the octahedral prism to rotate at a high speed, and reflects the infrared laser emitted by the laser generator to the convex lens A. It becomes parallel light, and then collects on the photosensitive element C through the convex lens B in the infrared receiving probe. The photosensitive element C converts this signal into a corresponding electrical signal and sends it to the other end of the comparator to compare with the original signal. When there is no object to be measured in the measuring probe, the pulse signal at both ends of the comparator will be the same. Therefore, there is no difference output: when there is an object to be measured in the measuring probe, the photosensitive element C will output no pulse signal during the period of scanning through the object to be measured. Therefore, there will be a difference input for a period of time at both ends of the comparator, which corresponds to the diameter of the measured object. By calculating the oscillation period of the pulse and the length of the time slice without pulse, the diameter of the measured object can be known.

Trimble MultiTrack Technology Trimble MultiTrack technology locks on and tracks passive prisms for applications such as monitoring or control measurements and active targets for dynamic measurement, stakeout and grade control applications. Active targets provide enhanced dynamic tracking performance and guaranteed lock to the correct target, especially in dusty construction site conditions. Up to 16 unique channels of target identification can be used to differentiate survey crews and grade checkers from machine control operations, eliminating down time caused by unnecessary interference. Unmatched Dynamic Positioning Grade control for earthmoving and fine grading machinery requires an updated, highly accurate position delivered on a very frequent basis. The more data provided, the smoother the hydraulic control and the higher gear that the machine can operate in. The Trimble SPS730 and SPS930 instruments deliver an unmatched 20 hertz update rate combined with low latency, synchronized data measurements for unmatched machine performance. Combined with the Trimble MT900 active machine target they can operate at ranges up to 700 meters at /-45 degree slopes, in the highest gear and in the dustiest conditions at the same time delivering the smoothest and most accurate finish available. Repeatability in the accuracy of graded layers results in fewer passes, reduced fuel and maintenance, reduced rework not to mention material savings, time and associated cost benefits.

BaF2 window crystals or Barium Fluoride window crystals, with their extremely broad transmission range from the deep UV to LWIR spectrum, are prevalent for Infrared applications requiring additional transmission in the Ultraviolet region. BaF2 window crystals are excellent when being used for IR spectroscopes and as viewport windows for thermal imaging inspection in electric power facilities and petroleum industries. A low refractive index of 1.48 implies BaF2 windows have high transmission rates without anti-reflection coating. BaF2 window crystals has similar properties to CaF2, the difference mainly lies in that barium fluoride window is more resistant to highly energetic radiation, and with an equivalent thickness, the transmission range of BaF2 window extends approximately 1 micron further into the long-wave IR region than calcium fluoride. BaF2 window crystals could also accommodate high-temperature environments up to 800 â??. However, exposure to moisture will increase its sensitivity to temperature and reduce its transmission rate to UV lights.

OST Photonics offers various functional crystal materials for laser systems, optical equipment and instruments. Crystals are divided into six types according to their functions: laser crystals (diffusion bonding crystals, Nd:YAG, Er:YAG, Yb:YAG, CTH:YAG, Nd:Ce:YAG, Nd:YVO4, Nd:GdVO4, Nd:YLF, Pr:YLF, Ho:YLF, Tm:YLF, Ti:Sapphire, Er:Yb: Glass), nonlinear crystals (KDP & DKDP), KTP, LiNbO3, LBO, BBO, BIBO), passive Q-switch crystals (Cr4+:YAG, Co2+:MgAl2O4), birefringent crystals (YVO4, �±-BBO), Magneto-optic Crystals (TGG) and optical crystals (BaF2, CaF2, MgF2, LiF, Germanium single crystal, Sapphire (Al2O3), YAG, ZnSe, Silicon single crystal, ZnS). If you want to know more about our functional crystals, please do not hesitate to contact OST Photonics. What are Functional Crystals? A wide range of functional crystal materials is used in various optical applications. While optical glass is commonly used as a transparent material, different functional crystal materials, primarily monocrystalline materials, are required for diverse applications due to their unique functionalities: In contrast to glass, birefringent crystals can exhibit birefringence, which is a requirement for various types of polarizers, wave plates, birefringent tuners, and other optical components. Commonly used birefringent crystal materials include YVO4, �±-BBO, quartz, calcite and sapphire. The lattice symmetry of a crystal material is not too high (such as a triangular, quadrilateral, or single prism), and it can exhibit nonlinearity. Nonlinear crystals are primarily used for nonlinear frequency conversion but also find applications in optical modulators like the Pokel cell. A wide variety of functional crystal materials can be used as laser crystals, serving as host materials for laser-active dopants (rare earth ions or transition metal ions). They typically exhibit relatively high transition cross sections, small gain bandwidth, and good heat conduction compared to laser-active glasses. In general, they also allow for higher doping concentrations. In some cases, functional crystal materials are used in spectral regions where glass does not have a wide enough wavelength range and high transmittance. In particular, various materials such as zinc sulfide (ZnS), zinc selenide (ZnSe) and Sapphire (Al2O3) are used as infrared crystals, and other materials such as lithium fluoride (LiF), calcium fluoride (CaF2) and magnesium fluoride (MgF2) are used as ultraviolet crystals. Some functional crystal materials, such as terbium gallium garnet (TGG), exhibit the Faraday effect (polarization rotation caused by magnetic fields), and they can be utilized in devices like Faraday rotators and Faraday isolators.
