Diamond has some remarkable properties: for example, its refractive index is 2.4, which is very high, and can be made into thinner optical components for optical systems with the same optical power. Their thermal conductivity is 2000 W/m*K, 1400 times higher than that of optical glass.

So far, polycrystalline diamond substrates have only been used as light windows for carbon dioxide lasers. Due to impurities and defects, they absorb and scatter laser radiation at the emission wavelength of 1 micron, so they are not suitable for fiber lasers. Although single crystal diamonds do not have this problem, they are difficult to manufacture. Over the years, the German Fraunhofer Institute for Applied Solid State Physics (IAF) has been devoted to the production of single crystal diamond. The continuous vapor deposition (CVD) reaction chamber developed in IAF has stable plasma conditions and it can produce a substrate with a thickness of several millimeters.

It can simultaneously process 60 diamonds at most. At a rate of up to 30 microns per hour, the reaction chamber can produce an optical element with an aperture of about 10 millimeters.

The lenses made of these synthetic single crystal diamonds have low absorptivity and low birefringence. At present, some samples coated with antireflection film have been provided and used in fiber laser cutting head. "We have optimized a complete hyperion laser optical system for diamond lenses for the first time, and the weight of the cutting head has been reduced by 90%," said Martin Traub of the Fraunhof Institute of laser technology".

The lens with a diameter of 7mm has passed the test of 2 kW laser power, without any problems. Now, partners have built a cutting test system using 1kW fiber lasers. Water cooling and protective gas supply are integrated in the cutting head. Process monitoring has not been planned. Currently, compact cutting heads is in process of testing for the first time.

A new optical system will significantly enhance the flexibility of laser cutting. The small size enables the system to process inaccessible areas, while the low weight is beneficial to the high dynamic motion in the 3D process.

Laser projector advantages:

1. Clear image

Ordinary projectors require us to put them in the right place to the screen as far as possible, but the laser projector 1080p does not have this problem. Even if the projector is placed in the corner, the projected picture does not have any distortion. Laser projection does not produce ambiguity anywhere.

2. High chroma

In terms of display effect, because laser projector 1080p simulates natural colors, the colors and layers are also more abundant. The wavelength of the light is fixed, so it looks comfortable, without the blinding discomfort of the bulb. More importantly, ultraviolet radiation without traditional light source makes the eyes relax when they look at the picture, which is incomparable with either projection device or active luminescence device.

3. Long service life

The lifetime of laser projector 1080p is four times longer than that of a traditional projector.

 Disadvantageof laser projector 1080p:

1. Relatively expensive

Ultrasonic cell crushing apparatuses convert electric energy into sound energy through transducer. This kind of energy changes into dense bubbles through the liquid medium, and these bubbles burst rapidly, thus playing the role of breaking cells and other substances.

Principle

The principle of ultrasonic cell crushing apparatuses is not very mysterious and complicated. In short, it transforms electric energy into sound energy through transducer, which is transformed into dense bubbles through liquid medium. These bubbles burst rapidly, thus playing a role in breaking up cells and other substances.

Ultrasound is a kind of elastic mechanical wave in material medium. It is a kind of wave form. Therefore, it can be used to detect physiological and pathological information of human body, that is, diagnostic ultrasound. At the same time, it is also an energy form. When a certain dose of ultrasound is transmitted in the organism, through the interaction between them, it can cause changes in the function and structure of the organism, that is, ultrasound biological effect. The main effects of ultrasound on cells are thermal effect, cavitation effect and mechanical effect. Thermal effect: when ultrasound propagates in the medium, the friction hinders the molecular vibration caused by ultrasound, and transforms part of energy into local high heat (42-43 ℃), because the critical lethal temperature of normal tissue is 45.7 ℃. However, the sensitivity of tumor tissue is higher than that of normal tissue, so the metabolism of tumor cells is blocked at this temperature, and the synthesis of DNA, RNA and protein is affected, thus killing the cancer cells while the normal tissue is not affected. Cavitation effect: under ultrasound irradiation, vacuoles are formed in the organism, and mechanical shear pressure and turbulence are produced along with the vibration and violent explosion of vacuoles, resulting in tumor bleeding, tissue disintegration and necrosis. In addition, when the cavitation bubble breaks, it will produce instantaneous high temperature (about 5000 ℃), high pressure (up to 500 × 104pa), which can make the water vapor dissociate and produce OH and H. The redox reaction caused by OH and H can lead to polymer degradation, enzyme deactivation, lipid peroxidation and cell killing. Mechanical effect is the primary effect of ultrasound. In the process of ultrasound propagation, the media particles alternately compress and expand to form a pressure change, causing cell structure damage. The killing effect is closely related to the frequency and intensity of ultrasound.

Key points for purchase

The ultrasonic generator

The signal generator generates a signal of a specific frequency, which is the frequency of the transducer. Generally, the ultrasonic frequency used in the ultrasonic equipment is 20kHz, 25kHz, 28kHz, 33khz, 40KHz, 60KHZ.

Transducer assembly

The transducer assembly is mainly composed of transducer and horn.

Loudspeaker box

It can effectively reduce the noise produced in the process of work, which can keep the laboratory quiet.

The application of ultrasonic cell crushing apparatuses in our country is in the mature stage, but the application is still not popular. The application range of this instrument (equipment) is very wide, which is incomparable with other instruments and equipment. Therefore, the market potential of the instrument (equipment) is great, and manufacturers are increasing. At the same time, it also causes the relative chaos of ultrasonic cleaning industry and market, which can be described as "a mixture of good and bad".

Particle size measurement using static light scattering

The particle size distribution as a parameter to specify a powder or dispersion plays a central role in many applications. Examples are construction material (sands, cements), pharmaceutical development, lime stones, ceramics, colored pigments, fertilizers, emulsions and may more. The range of applications is increasing permanently and hence the requirements on the measurement methods regarding size range, measuring time and reproducibility. Particularly the precise and reproducible detection of particles with sizes close to the measuring range limits as well as the simultaneous determination of particle sizes of very small particles (nanometer range) as well as large particles (lower millimeter range) for the characterization of polymodally or very broadly distributed samples provides a challenge. State-of-the-art laser diffraction devices such as the  particle size analyzer for sale solve these tasks by an innovative design of the optical bench for the detection of backscattered light of very small particles and by detecting large particles by an integrated high-speed CCD camera or the combination of static light scattering and Automated Imaging.

Measuring method
In static light scattering laser light (monochromatic, coherent light) interacts with the particles, which have to be characterized in terms of particle size. In dependence of the particles'size, the light waves are scattered by the particles in a characteristic manner: the larger the particles are, the greater is the scattering in forward direction. With particles smaller about 100 nm, the scattering intensity is nearly identical in all directions.

The scattering intensity is determined by stationary detectors depending on the angle (light scattering intensity distribution). State-of-the-art laser diffraction systems such as the Bettersizer S3 Plus guarantee the determination of scattering intensities in a continuous angular range of 0.02 – 165°, i. e. in forward, side and backward direction. This is achieved by means of a so-called double lens design and oblique incidence optical system (DLOIOS technology): Fourier lenses (collective lens) are positioned between the laser and particles as well as between particles and detectors. The particles will interact with the light within a parallel laser beam. This offers the advantage that the scattered light can also be detected at very large angles (in backward scattering direction) and thus even very small particles can be measured precisely. Thanks to DLOIOS technology, the problems of conventional measurement setups can also be avoided. Therefore, neither the suitable lenses for the corresponding particle size measurement range have to be selected prior to the measurement (in comparison to the Fourier optics), nor do measurement inaccuracies result from different particle to detector distances, if not all particles lie in one plane (in comparison to the inverse Fourier optics).

To calculate the particle size distribution from the measured scattering spectra, the theory of either FRAUNHOFER or MIE is applied. The FRAUNHOFER theory is based on the hypothesis of opaque and spherical particles: the scattered pattern corresponds to a thin opaque two-dimensional plate – diffraction only occurs at the edges. Therefore no additional optical input constants of the material are necessary for this calculation. However, this theory is only suitable for mean particle sizes from approx. 5 µm.

In contrast the MIE theory uses the hypothesis of virtually translucent and spherical particles, meaning that the light permeates the matter and is scattered elastically at the atoms of the particle. The knowledge of the complex refractive index of the particles and the liquid as well is necessary. This theory is applicable for particles of all sizes.

The following figure shows an example of a volume-related particle size distribution of a calcium carbonate powder – measured with a Bettersizer S3 Plus.
