真理光學儀器有限公司專注于Gao端顆粒表征儀器的研發(fā)和制造,產品涵蓋激光(衍射法)粒度分析儀、動態(tài)光散射納米粒度及Zeta電位分析儀以及顆粒圖像分析儀,既有實驗室儀器,又有在線檢測系統(tǒng)。真理光學秉持“科學態(tài)度,工匠精神”,為用戶提供世界Xian進的Gao端產品和服務。

真理光學匯集了以張福根博士為代表的全國顆粒表征領域的頂尖人才。張福根博士現(xiàn)任本公司董事長兼首Xi科學家,還擔任全國顆粒表征及分檢與篩網標準化技術委員會副主任委員、天津大學兼職教授,曾擔任中國顆粒學會副理事長,同時也是“歐美克”字號公司的創(chuàng)始人。曾擔任英國某粒度儀器公司中國總經理20余年的秦和義先生擔任本公司商務總經理,中國顆粒學會青年理事潘林超博士、陳進博士擔綱公司的研發(fā)主力。

激光(衍射法)粒度儀雖然已得到廣泛應用,但它并不Wan美,不論是科學基礎方面,還是技術方案方面。真理光學的團隊針對當前市面上儀器存在的不足,展開了系統(tǒng)的理論研究和技術創(chuàng)新,發(fā)現(xiàn)了衍射光斑(愛里斑)的反常變化現(xiàn)象(ACAD),解釋了為什么不能測量3μm左右的聚苯乙烯微球,并給出了反常區(qū)(不能測量粒徑)的一般公式;研究了衍射儀器的測量上限和下限;研究了顆粒折射率偏差對測量結果的影響,發(fā)明了兩種根據散射光分布估算顆粒折射率的方法;提出了斜置梯形窗口技術方案(Zhuan利),解決了前向超大角測量盲區(qū)的問題,使衍射儀器的亞微米顆粒測量水平顯著提高;提出了統(tǒng)一的反演算法(專有技術),消除了不同計算模式給出不同結果的尷尬;設計出了高達20Kfps的超高速并行數據采樣電路,使干法測量的精度不亞于濕法測量,對高速噴霧場的測量(時間)分辨率也更高。

在納米粒度及Zeta電位儀方面,真理光學提出了比相位分析法(PALS)更先進的余弦擬合相位分析法(CF-PALS),用光纖分束取代了傳統(tǒng)的平板分束鏡分束,用光纖內光干涉取代了自由空間干涉,使Zeta電位的測量重復性大幅度提高。

Linkoptik Instruments specializes in the development and manufacture of high-end particle characterization instruments, including laser (diffraction) particle size analyzers, dynamic light scattering nano particle size and zeta potential analyzers, and particle image analyzers, both laboratory instruments and online inspection systems. Linkoptik Instruments upholds the "scientific attitude and craftsmanship" to provide customers with the world's advanced high-end products and services.

Linkoptik Instruments has gathered the top talents in the field of particle characterization in China, represented by Dr. Fugen Zhang. Dr. Zhang is the Chairman and Chief Scientist of our company, and is also the Vice Chairman of the National Technical Committee for Particle Characterization and Sieving and Sieve Standardization, a part-time professor of Tianjin University, and the Vice Chairman of the Chinese Particle Society. Mr. Qin He Yi, who was the general manager of a particle size instrument company in China for more than 20 years, is the commercial general manager of the company, and Dr. Pan Linchao and Dr. Chen Jin, the young directors of the Chinese Particle Society, are the main R&D team of the company.

Although laser (diffraction) particle size measurement has been widely used, it is not perfect, both in terms of scientific basis and technical solutions. The team at Truth Optics has conducted systematic theoretical research and technological innovation to address the shortcomings of the current instruments on the market, discovered the phenomenon of anomalous variation of diffraction spot (Airy spot) (ACAD), explained why polystyrene microspheres around 3 μm cannot be measured, and gave a general formula for the anomalous zone (not measuring particle size); studied the upper and lower measurement limits of diffraction instruments; studied the effect of particle The influence of refractive index deviation on the measurement results was studied, and two methods for estimating the refractive index of particles based on the scattered light distribution were invented; an oblique trapezoidal window technical solution (patented) was proposed, which solved the problem of the blind area of the forward oversized angle measurement and significantly improved the submicron particle measurement level of the diffraction instrument; a unified inversion algorithm (proprietary technology) was proposed, which eliminated the embarrassment of different calculation modes giving different results; the design of The ultra-high speed parallel data sampling circuit of up to 20Kfps has been designed, which makes the accuracy of dry measurement no less than that of wet measurement, and the measurement (time) resolution of high-speed spray field is also higher.

In nanometer particle size and zeta potential measurement, Linkoptik Instruments has proposed a more advanced cosine fitted phase analysis method (CF-PALS) than PALS, replacing the traditional flat beam splitter mirror beam splitting with fiber optic beam splitting, and replacing free space interference with optical interference inside the fiber, which has greatly improved the repeatability of zeta potential measurement.

  干濕兩用激光粒度儀是一種性能優(yōu)良的粒度分布儀,干法分散系統(tǒng)采用文丘里分散效應,通過剪切、慣性、碰撞等方法粉體在通過測量窗口時處于充分分散狀態(tài),即使對難以分散的樣品如釹鐵硼粉,也能得到充分分散,得到的測量結果。干濕兩用激光粒度儀采用專門設計的由大規(guī)模集成電路工藝制造的大尺寸高靈敏度光電探測器陣列,分辨率高,性好;采用全程米氏理論和多種分布模型的數據處理方式;采用高精度的數據傳輸與處理電路等一系列的技術和制造工藝,使該儀器具有可靠、測試速度快、重復性好、操作簡便等突出特點,是集激光技術、計算機技術、光電子技術于一體的新一代干法粒度測試儀器。


  干濕兩用激光粒度儀主要原理:激光粒度儀作為一種新型的粒度測試儀器,已經在粉體加工、應用與研究領域得到廣泛的應用。它的特點是測試速度快、測試范圍寬、重復性和真實性好、操作簡便等等。


  1、激光法的粒度測試原理:


  激光粒度儀是根據顆粒能使激光產生散射這一物理現(xiàn)象測試粒度分布的。由于激光具有很好的單色性和*的方向性,所以一束平行的激光在沒有阻礙的無限空間中將會照射到無限遠的地方,并且在傳播過程中很少有發(fā)散的現(xiàn)象。


  當光束遇到顆粒阻擋時,一部分光將發(fā)生散射現(xiàn)象,散射光的傳播方向將與主光束的傳播方向形成一個夾角θ。散射理論和實驗結果都告訴我們,散射角θ的大小與顆粒的大小有關,顆粒越大,產生的散射光的θ角就越小;顆粒越小,產生的散射光的θ角就越大。在圖8中,散射光I1是由較大顆粒引起的;散射光I2是由較小顆粒引起的。進一步研究表明,散射光的強度代表該粒徑顆粒的數量。這樣,在不同的角度上測量散射光的強度,就可以得到樣品的粒度分布了。
