Qinhuangdao Intrinsic Crystal Technology Co., Ltd.  

Product Name: Germanium Plano Convex Lens/Optical Lens Model NO.: D5~D200mm Usage: Optical Trademark: ICC Origin: Qinhuangdao China HS Code: 9001909090 Product Description Germanium (Ge) Plano convex Lenses are made from Germanium material. They present a curvecd interface and a planar interface. They have a positive focal length, which makes it ideal for collecting and focusing light for many imaging applications. They are for instance the microlenses situated on top of a wafer, and also encountered in macroscopic optical systems.Specifications:Material:-----------------------------------------------------------GermaniumDiameter Tolerance:----------------------------------------------+0.0/-0.15mmFocal Length Tolerance (mm):----------------------------------+/-2%Centration:---------------------------------------------------------<3 arc minutesClear Aperture:---------------------------------------------------->85%Surface Figure:-----------------------------------------------------<λ/4@633nmSurface Quality:-----------------------------------------------------60/40Protected Bevel:---------------------------------------------------<0.25mmx45degCoating:--------------------------------------------------------------uncoatedPart No.F(mm)f(mm)R(mm)Tc(mm)Te(mm)Fb(mm)PCX6-10112.725.010.663.91.822.27PCX610212.750.021.312.81.848.0PCX6-10312.775.031.972.451.873.3PCX6-20125.450.021.316.01.845.8PCX6-20225.475.031.974.451.871.9PCX6-20325.4100.042.633.751.897.4PCX6-20425.4150.063.943.11.8147.8PCX6-20525.4200.085.253.02.0197.9PCX6-20625.4250.0106.562.82.0248.0PCX6-20725.4300.0127.882.652.0298.1PCX6-20825.4500.0213.132.42.0498.3PCX6-20925.41000.0426.262.22.0998.5See the following in our stockmodelDiameterD,mmFocal lengthFLx,mmRadius of CurvatureR,mmCenter Thicknesstc,mmThickness temin,mmICC140112.712.738.102.52.0ICC140212.719.057.152.42.0ICC140312.725.075.002.32.0ICC140419.0519.057.152.82.0ICC140519.0525.075.002.62.0ICC140619.0550.0150.002.32.0ICC140719.0575.0225.002.22.0ICC140825.425.075.003.12.0ICC140925.450.0150.002.52.0ICC141025.475.0225.002.42.0ICC141125.4100.0300.002.32.0ICC141238.150.0150.004.23.0ICC141338.175.0225.003.83.0ICC141438.1100.0300.003.63.0ICC141538.1150.0450.003.43.0ICC141650.850.0150.005.23.0ICC141750.8100.0300.004.13.0ICC141850.8150.0450.003.73.0ICC141950.8200.0600.003.53.0ICC142050.8250.0750.003.43.0
