Calcium FLuroide_CaF2: 0.19-9.0um, T>email@example.com, 3.0mm thickness witness testing.
Material size: poly crystal less than 280mm, mono crystal less than 220mm, minimum size more than 3.0mm.
Material tolerance: Ground rod size : +/-0.5mm, Cutting disc tolerance: +/-0.2mm, fine grinding tolerance: +/-0.1mm
Standard rod size:
Standard delivery time: rod and disc 3-7days, polishing parts 3-5weeks.
CaF2 orientation <111>, and we can change the orientation to <111>,<110> and <100> via cutting and grind. But it will increase the rod losses, and labor cost, so the orientation requirement effect the price much, if your need this parameters, please marked that in your RFQ.
CaF2 can be divided into mono crystal and poly crystal structure. In fact the performance have no difference for application in protect windows and commercial infrared imaging process, but it do have a big difference in high power laser and imaging systems fields which usually ask for large size mono crystal with low stress. The mono crystal price is higher price of 1.5-2.0times than the poly crystal. And at the meanwhile the growth technique is more difficulty when size than 50mm, and is a very low recovery when size more than 100mm. so the price will be increased much when size is increased for mono crystal.
CaF2 can be divided into UV and IR grade. The UV grade have a better transmission in ultraviolet wavelength (190-350nm), and the transmission is similar as IR grade in other wavelength, but it required low refraction stress, so the growth material cost is higher than IR grade. Please state the application wavelength when you ask for a quotation.
CaF2 crystal has a low value of hardness, and it can be polished by diamond power in a clear condition. We can supply grade III in large requirement and can supply grade II for small customized optics.
Core business: Calcium Fluoride, Barium Fluoride, and Magnesium Fluoride Growth and Stock parts Sales.Optical Fluorides crystal have a good transmission from UV, VIR, and MIR wavelength, the transmission can be more than 85% without coating. And at the same time, the advanced grinding and polishing technique and low cost material have the crystal widely applying in chemical industry, heavy vessel, military aviation, infrared inspection, medical beauty, and optical imaging fields. It can be made into various kinds of optics elements, say windows, lenses, prism, and mirrors.We have 10sets material growth machines, 4sets cutting machines, 1set orientation finding machines, 2set laser machines, and 1set interferometer. We can supply integrated report for the material bubbles, stress, and transmission, and can supply the crystal rod and cut disc in a better price with very fast shipment say 3-5days, and can supply dimension size range from 5.0mm to 220mm mono crystal and poly crystal in production quantity.CaF2: , max mono crystal 200mm, poly crystal 280mm, <111>,<100>BaF2: max mono crystal 80mm, poly crystal 150mm, <111>,<100>MgF2: max mono crystal 150mm, poly crystal 300mm, <111>,<100>We also supply fluoride crystal and other optical glasses grinding and polishing service. Say BK7, Fussed silica, mono crystal silicon, optical grade germanium, and have a better competition in medium to large optics windows requirement. We can supply 5000 units windows for size Diameter 120mm windows per month. And also build a common commercial stock for small lab requirement.We believe that improved quality, faster delivery, and better price will win us a long term mutual cooperation among all of our customers’ vendors.
