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. Spherical Lens Surface Quality 60/40 Scratch and Dig Focal Length Tolerance ±2% Union Optic provides some stocked standard lenses for your selection, including BK7 series and fused silica series. And also we make custom lens for you! Call us for your special 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...

Optical Element—Laser Beam Expander Standard Product Laser Beam Expander Laser Beam Expander is used to compress the divergence angle of the beam by expanding the diameter of the laser beam, so it is widely used in laser ranging system or laser focus system. The beam through a laser beam expander features a smaller divergence angle, which can achieve the ideal effect in long distance measurement, and also we can get smaller and higher energy beam spot in the laser processing • Consists of Two or Three Lenses • Expand Laser Beam Diameter • Compress Beam Divergence Angle • Multi Wavelengths &...
