The raw material is known as silicon or Si. It is the second most abundant element in the earth after oxygen. Silicon is mostly found in silica sand or silica stone, but it is also found in natural water, trees, plants, etc. The chemical symbol for silicon is SiO2. It needs to be refined because it is combined with other substances in nature. Silicon wafers are formed by cutting ingots into 1mm wafers and then repeatedly grinding, polishing, etching and cleaning them to form a mirror-like smooth surface, which can be used as a substrate material for semiconductor electronic devices.

An optical prism is a piece of glass or other transparent material that is cut at precise angles and planes. It can be used to analyze and reflect light. Ordinary triangular prisms can split white light into its component colors, which called spectrum. Each color or wavelength that makes up white light is bent or refracted into different quantity. Shorter wavelengths (which are toward the end of the purple in the spectrum) bend the most, while longer wavelengths (which are toward the end of the red in the spectrum) bend the least. This kind of prisms are used in certain spectroscopes, because it can analyze light and determine the identity and structure of materials that emit or absorb light. Optical prisms can reflect, disperse, or split light. They are usually made of glass. As long as the material is transparent and the wavelength can be designed, it also can be made into prism. The common materials include glass, plastic, and fluorite.Optical prisms can reverse the direction of light through internal reflection. They are widely bused to periscopes, binoculars and spotting scopes.

The cut-off band of a filter is adjacent to both sides of the transmission band of the spectral characteristic curve, which is called Bandpass filter. Bandpass filters can be roughly divided into broadband filters and narrowband filters according to their spectral characteristics. But there is no clear boundary for this division. The two kinds of filters are usually combined. It applies the principle of light wave interference. Bandpass filters are widely used in various fields. The spectral transmission area near the wavelength is called the pass band of the filter. Usually, there are cut-off areas on both sides, and there may be bypass bands around the cut-off area, which can be eliminated by the colored glass, absorbing films, or cut-off filter. Bandpass filters can be used in cable TV upgrade equipment, wireless transmission equipment, mobile phone barcode scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical equipment, infrared ink recognition, red film recognition, face recognition sensor system , hand-held infrared laser rangefinders, optical instruments, medical and health equipment and testing instruments.

Ce:YAG is a fast scintillator with excellent mechanical and chemical resistance. Ce:YAG scintillation detectors are preferred for electron microscopy, beta and X-ray counting, as well as for electron and X-ray imaging screens. The material`s mechanical properties enable production of thin screens down to 0.005 mm thick. Does not degrade when bombarded by electrons or ions, thus making Ce:YAG suitable for high current operations. Light emission peaks at about 560nm (yellow) which means that an S20 photomultiplier is most suitable for detecting the emission. Response is better for Ce:YAG than for Planotec P47 discs below 5kV and again at higher accelerating voltages over 100kV, where the performance of powder scintillators falls off while Ce:YAG response increases linearly. Although the signal from Ce:YAG and Ce:YAP is less than the P47, the S/N ratio is better and therefore the final signal is better. Decay time approx. 60 nanoseconds. The side towards the light guide is micro-textured to increase light emission. Can be cleaned (polished) and recoated. Best to coat with 50nm Al to avoid light sensitivity.

It is more suitable for diode-pumping than the traditional Nd-doped systems. It can be pumped at 0.94 μm laser output. Compared with the commonly used Nd:YAG crystal, Yb:YAG crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-state lifetime, three to four times lower thermal loading per unit pump power. Yb:YAG crystal is expected to replace Nd:YAG crystal for high power diode-pumped lasers and other potential applications. Advantages: • Very low fractional heating, less than 11% • Very high slope efficiency • Broad absorption bands, about 8nm@940nm • No excited-state absorption or up-conversion • Conveniently pumped by reliable InGaAs diodes at 940nm(or 970nm) • High thermal conductivity and large mechanical strength • High optical quality

Nd:GdVO4, is a promising material for diode pumped lasers. Similar to the more well-known Nd:YVO4 crystal, Nd:GdVO4 crystal also exhibits high gain, low threshold, and high absorption coefficients at pumping wavelengths. Nd:GdVO4 has the additional advantage over Nd:YVO4 of a much higher thermal conductivity. For CW lasing at 1.06 um and 1.34 um and intracavity doubling with KTP and LBO, the gadolinium vanadate have produced a higher slope efficiency or optical conversion than Nd:YVO4.

Nd:YVO4 is one of the most promising commercially available diode pumped solid state laser materials. It has high laser induced damage threshold and good mechanical in addition to optical properties. Its large stimulated emission cross-section and high absorption of pump laser make it a right crystal for pocket laser. Nd: YVO4 can produce IR green and blue laser by using minor different set-up. A broad absorption band centered at 808nm and favorable mechanical properties make Nd:YVO4 well suited for compact, efficient, high power diode-pumped lasers. Natural birefringence gives rise to a highly polarized output at 1064.3 and 1342nm.

The filter is made of glass and special dyes. The blue filter can only let blue light pass through. Compared with ordinary glass,the molecular structure and refractive index of blue filter have changed, and the passage of some color light has changed. For example, when a white light passes through a blue filter, it emits a blue light, while the green light and red light are very few, and most of them are absorbed by the filter. The filter plays a very important role. It is widely used in photography.

We provide customers with various materials and various sizes of powell prisms. Powell Optical glass prism is also called laser linear generator lens. Unlike cylinder lens, the dome of Powell optical glass prism is actually a complex two-dimensional aspheric curve, which will produce a lot of spherical aberration and redistribute light along the line; Reduce the light in the center area while increasing the light level at the end of the line, transforming the laser beam into a uniform straight line. Cylindrical Lens will produce poorly illuminated lines with fading edges and hot spots in the center, while the straight lines produced by Powell Optical glass prisms have uniform energy distribution and uniform light distribution along the line.The Optical Prisms provide uniform energy distribution along the entire length of the line. What is the function of Powell lens? Powell Optical glass beamsplitter are currently widely used in industrial and research applications, where uniform intensity distribution is essential, because lasers are used as illumination sources, or, for example, in material processing, when the entire area irradiated by the laser must be processed to be uniform and equal The way. Powell lenses will produce a very uniform line of illumination for a variety of machine vision applications; from biomedical and automotive assembly to chocolate chip cookie production.
