How to order germanium products from our HENGXIANG factory?As you may find from our webpage, our HENGXIANG factory can provides a series of germanium products, such as germanium grain, germanium lenes, germanium window plate, germanium substrate, germanium stone,germanium powder, germanium ingot Competitive Advantage1. Strict raw materials control: raw materials are all new and original bought from the source factory2. Low heavy metal content: content of Mg, Al, Pb, As, Ni, Hg less than 1ppm3. Customized packaging:packed by plastic vacuum bag4. Quality Guarantee: If any quality problems, free replacement will be adoptedCharacteristics of the our germanium products: Purified germanium is a 'p-type' semiconductor material. Conductivity depends largely on added impurities. Attacked by nitric acid and aqua regia, but stable in water, acids, and alkalies in absence of dissolved oxygen, low toxicity.the resistivity of the germanium can be over 3000Ω or around 1000 Ω for P typethe resistivity of the germanium can be 3-50Ω for N typeApplications:germanium is mainly used as a semiconductor material for transistors. The first generation of semiconductors were based solely on germanium. However, most of today’s semiconductor production is based on silicon and germaniums use in electronics are in fibre-optic systems, infrared optics and in solar cell applications..Substrate: monocrystalline germanium, P shape or N shapeDimensions； diameter and thicknessThe tolerance of the dimensionSurface Quality:The surface quality of an optical component is an evaluation of the surface imperfections, such as scratches and pits, or digs, which may be caused during the manufacturing or handling process,such as 60/40,40/20 or 20/10.this is depends on your actually needs.Surface Irregularity:this always refers to any measured deviation of an optical surface from its intended shape, such as λ/4 λ/8. λ/10 or other paramters can be customzied.
How to place an order of optical filters?It is in common that an optical filter is a optical plane that selectively transmits light of different wavelengths, usually implemented as a glass plane or plastic device in the optical path, which are either coated in the bulk or have interference coatings.Our HENGXIANG factory can offer many kinds of optical filters including color glass filter, neutural density filter, band pass filter, IR cut filter, IR pass filter, birefringent filter, interference filter, etc.. 1.For longpass filters: longpass filters are designed to have a sharp transition from reflection to transmission, making them ideal for various applications. Available in a variety of cut-on wavelengths, these filters are designed for fluorescence,order sorting applications, and Display. Eliminate stray light by creating custom bandpass filters when combined with shortpass filters . A single layer AR coating on the back surface enhances the overall efficiency of each filter.2.Shortpass filters:Shortpass filters are designed to have a very sharp transition from transmission to reflection, making them extremely useful in a number of applications. Available in a variety of cut-off wavelengths, they are ideal for fluorescence applications, Display, separating spectral orders, and creating custom, efficient bandpass filters when combined with longpass filters. With an average transmission of 85% and a blocking optical density of 2.0, excellent contrast can be achieved in machine vision and gauging applications. A single layer AR coating on the back surface enhances the overall efficiency of each filter.3. Color Glass Filter: its selective absorption in visible wavelength range, color glass filter will exhibit various color depending the glass type. Color glass filter provides an economical filter for various applications, such as camera filter, machine vision lens filters, industrial measurement, environment protection and so on. 4.Birefringent Filter：this kind of optical filter is made by crystal quartz. It's used in the laser cavity for wavelength selection. We can provide different thickenss birefringent filter for our customer's laser applications. In a word, our HENGXIANG factory can provides a series of optical filters, and if you can offer the whole specifactions of the optical fitler you need, we will quote you in a very short time. Substrate: H-K9L, UV Grade Fused Silica ,sapphire or any other optical material requested Dimensions； diameter and thicknessThe tolerance of the dimensionSurface Quality:The surface quality of an optical component is an evaluation of the surface imperfections, such as scratches and pits, or digs, which may be caused during the manufacturing or handling process,such as 60/40,40/20 or 20/10.this is depends on your actually needs.Surface Irregularity:this always refers to any measured deviation of an optical surface from its intended shape, such as λ/4 λ/8. λ/10 or other paramters can be customzied.Parallelism &Flatness:
How to place an order of optical lensesAs we may known, optical lenses have many application, such as the simple collection of the scaning of laser beams ,precise imaging and image transfer.There are many basic kinds of optical lenses, including single lenses, cylindrical lenses and achromatic lenses .Based on the various applications of different kind of optical lens,our HENGXIANG factory provides the lenses with materials of BK7,BK9, fused silica,infrared material(such as germanium, silicon,quartz and sapphire )Here we listing some common types of optical lenses: Plano-Convex LensDouble-convex LensCylindrical lensesDouble-Concave LensPlano-Concave LensAchromatic Lenses - Doublet lensesAs soon as we known about the common types of the optical lenes, next, you need to provides the whole specications :1.Material: BK7,BK9, fused silica,infrared material(such as germanium, silicon,quartz and sapphire )Design Wavelength: wavelength is the distance from one crest to another, or from one trough to another, of a wave (which may be an electromagnetic wave, a sound wave, or any other wave) Dimensions； diameter and thicknessThe tolerance of the dimensionSurface Quality:The surface quality of an optical component is an evaluation of the surface imperfections, such as scratches and pits, or digs, which may be caused during the manufacturing or handling process,such as 60/40,40/20 or 20/10.this is depends on your actually needs.Focal Length:focal length is the distance from the center of the lens to the principal foci (or focal points) of the lens, including front focal length and back focal length.Centration: The degree to which the optical axis of a lens and the mechanical axis of its mounting coincide, usually <3 arc minutesClear Aperture: is defined as the diameter or size of an optical component that must meet specifications.The limited light-gathering area of an optical system.The area is normally restricted to an edge or outer surface of an individual component, according the the characteristic of different material, the clear aperture of its technique is also different, such as >80%, or >85%.,>90% or even >95%.Surface Irregularity:this always refers to any measured deviation of an optical surface from its intended shape, such as λ/4 λ/8. λ/10 or other paramters can be customzied.AR coating: is a type of optical Anti-Reflective coating applied to the surface of lenses and other optical elements to reduce reflection, customer should offer the transmission rate of the wavelength range and the coating type if you would like to make AR coating, we could offer regular AR coating and multi-layer coating in a high curve and ranges.
