Our products have gained international recognition, with exports reaching the United States, Russia, France, Germany, South Korea, Indonesia, and beyond. At Rehoboth, innovation and quality drive us to deliver solutions that empower our global partners.
High-Purity Metal Oxide Powders
Precision Materials Powering Innovation
Engineered for Excellence
Our premium-grade metal oxide powders—including Tantalum Oxide (Ta₂O₅), Niobium Oxide (Nb₂O₅), Silicon Dioxide (SiO₂), Zinc Oxide (ZnO), and Aluminum Oxide (Al₂O₃)—deliver unmatched purity levels (99.9%-99.999%) for mission-critical industrial applications.
Where Innovation Meets Reliability
These ultra-fine powders are the invisible backbone of modern technology:
Coating is the use of physical or chemical methods to coat the surface of a material with a transparent electrolyte film, or a metal film, with the purpose of changing the reflection and transmission characteristics of the material surface.
In the visible and infrared bands, the reflectivity of most metals can reach 78%~98%, but not higher than 98%. Whether it is for CO2 laser, copper, molybdenum, silicon, germanium, etc. to make mirrors, germanium, gallium arsenide, zinc selenide as output windows and transmission optical element materials, or for YAG lasers to use ordinary optical glass as reflectors, output mirrors and transmission optical element materials, can not meet more than 99% of the requirements of total mirrors. Different applications require different transmittance of output mirrors, so optical coating methods must be used.
For the infrared band of CO2 laser projector, the commonly used coating materials are yttrium fluoride, praseodymium fluoride, germanium, etc.; For YAG laser projectors in the near-infrared band or visible light band, the commonly used coating materials are zinc sulfide, magnesium fluoride, titanium dioxide, zirconia, etc. In addition to high-reflection coatings and anti-reflection coatings, special coatings can also be applied to increase reflection at one wavelength and transmission to another wavelength, such as spectroscopic coatings in laser frequency doubling technology.
Optical lenses play a vital role in the field of optical instruments. Whether it is microscopes, medical devices, telescopes, spectrometers, lasers, they are all inseparable from the help of lenses. By focusing, magnifying, splitting, reflecting, and refracting light, they provide powerful technical support for scientific research, observation, and measurement.
1. Optical lenses play an indispensable role in cameras and camcorders. They precisely adjust the angle of incidence and focus of the light, ensuring that the captured images and videos are crisp and detailed.
2. A hub for optical communications
Optical lenses play a vital role in fiber optic communication systems. By focusing and coupling optical fibers, they ensure high-speed and efficient optical signal transmission, making them a key hub for the entire communication system.
3. Laser processing tools
Optical lenses play an indispensable role in the field of laser processing. They precisely focus the laser beam and adjust the intensity and shape of the laser to facilitate delicate operations such as cutting, welding, and punching.
4. Medical applications
Optical lenses play a key role in the medical field. They are widely used in eyeglasses and contact lenses to correct vision problems. At the same time, optical microscopes and endoscopes also rely on optical lenses for accurate observation and diagnosis, helping medical personnel to detect and treat lesions in a timely manner.
5. Photoelectric conversion and measurement
Optical lenses play an important role in optical sensors. They are used to efficiently collect and focus optical signals for photoelectric conversion and accurate measurement functions.
6. Applications in the automotive industry
Optical lenses play a variety of roles in automotive manufacturing. Lights use optical lenses to precisely focus and disperse light to ensure safe driving at night. The rearview mirrors, on the other hand, rely on optical lenses to reflect and expand the field of vision, providing the driver with more comprehensive information about the road conditions behind them.
Optical vacuum coating machine whether for mobile phones, digital products, or sanitary ware have the same decorative requirements products, optical coating through the bottom layer of the coating color film and transparent medium multilayer film to achieve a variety of colors, tones and metallic luster, and can be equipped with silk screen printing, heat transfer, laser engraving and drawing process, to get a variety of shades of dazzling luster, optical coating to strengthen the three-dimensional vision of stripes and patterns, it can also improve the performance of vacuum coating, and by improving the yield and stability of equipment, as well as reducing material consumption.
Optical vacuum coater coating refers to the process of coating a layer (or multiple layers) of metal (or dielectric) film on the surface of optical parts. The purpose of coating on the surface of optical parts is to reduce or increase the requirements of light reflection, beam splitting, color separation, light filtering, polarization, etc. Commonly used coating methods are vacuum coating (a type of physical coating) and chemical coating.
