Filters are designed by their manufacturers to transmit or absorb different wavelengths of light. And they are widely used in scientific experiments and industrial applications where that change is necessary. VY Optics Photoelectric Technology Co.,Ltd. can supply a full range of filter. They are short pass Filter, long pass Filter, band pass Filter, ultraviole Filtert, infrared Filter, heat absorbing Filter, and color temperature conversion filters. We use material by China to Schott, Hoya, and other manufacturers to process them. Metallic films, colored glasses and thin dielectric films filter are all available per your requirements.Specification of our color filter as follow:Material:Filter Glass,BK7Dimension: 4mm-160mm - 0.20mmSquares/Rectangles:1mm-165mmThickness:0.5mm-4mm Thickness tolerance:+/-0.01mm-0.1mmParalism: Up to 3 Arc minutesEdges:Fine Ground Flatness:Up to Lambda/10Surface quantity: 80/50-20/10 Scratch/Dig
Spherical Ball Lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ea
Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocites of the extraordinary and ordinary rays through the birefringent material vari
Plano-Convex Lens is widely use in optical display systems, projection optics systems, imagining optical systems, and laser measurement systems. It is best use where conjugate point-- object distance,
Rod Lenses are highly polished small diameter rods made of optically transparent homogeneous materials. A carefully controlled manufacturing process produces rods (or fibers) with precise diameters an
Wedge prism is an optical element having plane-inclined surfaces, usually the faces are inclined toward one another at very small angles. Wedges divert light toward their thicker portions.Wedge prism
A lens cover or lens cap provides protection from scratches and minor collisions for camera and camcorder lenses. Lens covers come standard with most cameras and lenses. Some mobile camera phones incl
Meniscus Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while mai
Nd:YVO4 crystal is one of the most excellent laser host materials, it is suitable for diode laser-pumped solid state laser. The crystal has these main features: low lasing threshold, high slope effici
In photography, a lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare.The geometry of the lens hood can vary f
