Optical Element─BK7/Fused Silica Optical MaterialBK7 is an excellent general purpose material widely used in Lensvisible and NIR optical components. BK7 is a borosilicatecrown optical glass. Window Transmission Range: 330nm~2100nm Mirror Thermal Expansion Coefficient: 7.5x10 /K Density: 2.52g/cm BeamsplitterFused SilicaFused silica is a widely used material with high chemical purity, good thermal characteristics and excellenthomogeneity. Very good thermal expansion characteristic is an outstanding feature of fused silica. FusedSilica is primarily used in wider thermal application. Fused silica includes UV grade and IR grade. Typical index Homogeneity: <8x10 Thermal Expansion Coefficient:0.58x10 /K (0℃ to 200℃) Density: 2.201g/cmWe default to use chinese fused silica, there are mainly three types of fused silica, JGS1, JGS2, JGS3,they are used for different application. Please refer to below for details.JGS1JGS1 is mainly used for optics operating in the UV and the visible wavelength range. It is free of bubblesand inclusions. It is equivalent to Suprasil 1&2 and Corning 7980.JGS2JGS2 is mainly used as mirror substrate, as it has tiny bubbles inside. It is equivalent to Homosil 1, 2&3. Prism Filter

Optical Material Optical Element─Quartz/CaFLens JGS3 JGS3 is transparent in the ultraviolet, visible and infrared spectral regions, but it has many bubblesWindow inside. It is equivalent to Suprasil 300.Mirror QuartzBeamsplitter Although crystal quartz is made of SiO2, it is different from fused silica, it is a positive uniaxial birefringentPrism crystal. It features its very small birefringent refractive index difference, so it is always used in waveplatesFilter and other polarization control application. Transmission Range: 200nm~2300nm Thermal Expansion Coefficient: ||a=13.2 x 10 /K, ||c=7.1 x 10 /K Density: 2.65g/cm CaF CaF is a cubic single crystal. It has good transmission from UV to middle infrared wavelength. It is always used in excimer laser components. While, it is a little hygroscopic and susceptible to thermal shock. Transmission Range: 170nm~7800nm Thermal Expansion Coefficient: 18.85x10 /K (20℃ to 60℃) Density:3.18g/cm

Optical Element─MgF /Al O /Si Optical MaterialMgF LensMgF is a tetragonal positive birefringent crystal. MgF has good chemical, mechanical and thermal Windowcharacteristics compared with CaF . Due to its high vacuum UV transmission and high damagethreshold, MgF is usually used in VUV and excimer laser windows, polarizers, lenses and etc. Mirror Lattice Constant: a=4.621A ; c=3.053A Beamsplitter Mohs Hardness: 6 Density: 3.17g/cm Prism Transparence Range: 120nm~7000nm Thermal Conductivity: 0.0075W/m/K Filter Thermal Expansion Coefficient:||a=13.7x10 /K ||c=8.48x10 /K Index of Refraction: @405nm n =1.3836, n =1.3957SapphireSapphire is a single crystal aluminum oxide (Al O ). Its Mohs hardness is 9, it is one of the hardestmaterials. Sapphire has good mechanical strength, and it is also transparent from visible to IRspectrum. So, it is always used as window material where scratch resistance is required. Lattice Constant: a =4.75 A ; c =12.97A Transparent Range: 180nm~4500nm Density: 3.98g/cm Mohs Hardness: 9 Melting Point: 2030℃ Thermal Conductivity: 0.04W/m/K Expansion Coefficient: 8.4x10 /K Refractive Index: 1.755@1umSiliconSilicon is a good IR material , it can be used from 1.2 to 7 microns, its peak transmission range is in 3-5 micron. Silicon can be used in some circumstances where weight is a concern as that the density ofSilicon is similar to optical glass. Silicon material is widely used in security and military applications. Transmission Range: 1200nm~7000nm Thermal Expansion Coefficient: 2.55x10 /K Density: 2.33g/cm

Optical Material Optical Element─Germanium/ZnSeLens GermaniumWindow Germanium is widely used in far infrared wavelength, it is transparent from 2 micron to 17 micron. Germanium also has higher refractive index about 4 at 10.6 micron. Germanium is very popular in FLIRMirror and imaging applications.Beamsplitter Transmission Range: 2000nm~17000nm Thermal Expansion Coefficient: 5.5x10 /K Density: 5.33g/cm ZnSe Transmission Range: 500nm~19000nm Thermal Expansion Coefficient: 7.6x10 /K Density: 5.27g/cmPrismFilter

Optical Element─Lens Overview Optical MaterialLens LensLens OverviewLens can converge or diverge the transmission beam and form image of the object, Which iswidely used in various applications.Usually lenses are not only used in visible band, but also in IR band and UV band, that meansspecial material should be used. Now, Union Optic can offer lenses made of various materialssuch as CaF , MgF , Sapphire, Silicon, Germanium, ZnSe and etc. Union Optic can also providevarious coatings for lenses upon your request.

Optical Element─Window OverviewOptical Material WindowLens Window Overview Windows are optical glass with polished faces that are relatively parallel. They are used to protect laser output. Always windows are AR coated to eliminate reflection, so AR coated windows offer improved transmission when used in industrial displays or computer monitors. Their high transmission makes them ideal for most industrial and laser protecting applications. Union Optic offers all types of windows made of different materials. Special size and materials are also available upon request. In addition, we provide various coatings on optical windows.Window Material Properties Application BK7 Transmission Range: 330-2100nm Excellent material for most application Refractive Index: 1.5164@588nm over visible and near IR spectrum.Mirror Fused Silica Transmission Range: 185-2500nm It is the best choice for resistance thermal Refractive Index: 1.4858@308nm application.Better transmission from UV Low Thermal Expansion Coefficient: to IR spectrum. 0.58 x 10 K-6Beamsplitter Sapphire Transmission Range: 180-4500nm Better transmission over the wide range Refractive Index: 1.755@1000nm spectrum, high scratch resistance, can be Calcium Strong Hardness used in application where scratch resist- Fluoride ance required.
