Optical Element—Material Overview^ Optical Material Material Overview Union Optic can supply many optical materials, like colorless optical glasses, color glasses, infrared materials, UV materials and also optical crystals. Usually, the material we used is Chinese material unless specified. If you can not confirm which material is the right one, please contact us. All the material we provided are RoHS Compliant! Refractive Index Transmission Thermal Expansion 3 Range(um) Coefficient (10*/K) Density(g/cm ) Fused Silica Crystal Quartz

JGS3 is transparent in the ultraviolet, visible and infrared spectral regions, but it has many bubbles inside. It is equivalent to Suprasil 300. Full Spectrum Fused Silica (JGS3) • Thermal Expansion Coefficient: 18.85x10 7K (20°C to 60°C)

Optical Element—MgF^AIA/Si MgF2is a tetragonal positive birefringent crystal. MgF2 has good chemical, mechanical and thermal characteristics compared with CaF2. Due to its high vacuum UV transmission and high damage threshold, MgF2 is usually used in VUV and excimer laser windows, polarizers, lenses and etc. Sapphire is a single crystal aluminum oxide (Al203). Its Mohs hardness is 9, it is one of the hardest materials. Sapphire has good mechanical strength, and it is also transparent from visible to IR spectrum. So, it is always used as window material where scratch resistance is required....

Optical Element—Germanium/ZnSe 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 FLIR • Thermal Expansion Coefficient: 5.5x10"6/K

Optical Element—Lens Overview Lens Overview Lens can converge or diverge the transmission beam and form image of the object, Which is widely used in various applications. Usually lenses are not only used in visible band, but also in IR band and UV band, that means special material should be used. Now, Union Optic can offer lenses made of various materials such as CaF2, MgF2, Sapphire, Silicon, Germanium, ZnSe and etc. Union Optic can also provide various coatings for lenses upon your request.

Unlike cylindrical lens, laser line generator lens can produce an uniform distribution of energy along the line. While, the input beam diameter must be smaller than • Creates Uniform, Straight Line • Several Fan Angles Available • Ideal for...

Optical Element— ^_Piano Convex Axicon Lens Standard Product Piano Convex Axicon Lens Plano-convex Axicon consists of one convex conical surface and one plane surface. It is always used to produce a non-diffractive ring-shaped beam in the near field, whose diameter will increase over distance while maintaining a constant ring thickness. When used with a collimated Gaussian beam, Plano-convex Axicon can create an approximation of a Bessel beam ideal for a range of medical, research, measurement, and alignment • Creates a Ring Shaped Approximation of a Bessel Beam • Many Apex Angles Available...
