MEMS VOA is a precise and adjustable voltage-driven optical component. The key part of the component is MEMS chip; driving voltage produces electrostatic force to drive the micro-mirror on the chip, then to adjust output optical power. It has excellent features such as compact dimension, low power consumption, fast responding, anti-shock, low WDL as well as low PDL. It is successfully applied in military project. It meets reliability standard of Telcordia 1221.MEMS VOA has 2 series: fast responding series and low voltage driving (LOWO) series. Each series has variable models like single wavelength, dual wavelength, and polarization-maintaining.We could also develop and produce other MEMS VOA as customers' requirement.
MEMS VOA is based on a micro-electro-mechanical system. Inside the MEMS VOA, a MEMS chip with a tilting mirror on the silicon is seated and wire bonded to the pins. A voltage applied to MEMS chip can causes the mirror to rotate, which changes the coupling of light between the input fiber and output fiber, thus the desired attenuation amount. MEMS VOA achieves highly repeatable optical attenuation over C or L Band. It gives Soloreinâ??s VOA an advantage in WDM, VMUX/DEMUX, EDFA and optical network protection applications.
The MM Series VOA is based on a proprietary micro-electro-mechanical mechanism
featuring compact design, simple construction, easy direct drive, and excellent optical performance. The MM series VOA is compliant with the Telcordia 1209 and 1221 reliability standards. The MM series VOA is available in either normally-open or normally-closed configurations and with an integrated tap option. The VOA is driven by applying an electrical voltage.

Talc is an amazingly variable mineral with a massive range of uses across several industries. It is the softest rock on the planet. Softness, water repellency, chemical inertness, platyness, and an affinity for organic compounds are all characteristics of talc
Talc is a highly desired multi-functional filler and process facilitator in a wide range of applications, including plastics, paper, ceramics, and paint.
The physical properties of talc are softness as it ranks 1 on the Mohs scale, natural affinity with oils making it an excellent hydrophobic mineral and its chemical inertness.
It is an extremely useful mineral in the manufacturing of solar panels, semiconductors and electronics, aluminium and steel alloys, and also in the construction sector, after being transformed into silicon (Si) through gaseous reduction at high temperatures.
Aryan Tiles is one of the biggest producers and suppliers for talc in India. We extract our talc mineral from several regions of Rajasthan. Our scientists and process experts collaborate with customers to develop innovative minerals that satisfy their specific industriesâ?? needs.
Talc, or talcum, is a clay mineral, composed of hydrated magnesium silicate with the chemical formula Mgâ??Siâ??Oâ??â??(OH)â??
Talc provide the ideal blend of stiffness and impact strength, allowing producers to create parts that are both thinner and lighter and thus reducing overall vehicle weight within the automation sector. It also improves rubber permeability, lowers tyre rolling resistance and increases vehicle fuel efficiency.
Further in the paints and coatings, talc works as an excellent natural alternative to less environmentally friendly TiO2 for increasing coating mechanical and optical qualities.
Moreover, in the pulp and paper industry, talc is great for preventing deposits, allowing mills to operate in closed water circuits, and maximizing prime resources.
Furthermore, in the ceramic tiles and sanitary ware, talc improves vitrification, allowing manufacturers to lower firing temperatures and shorten firing cycles.
In the agriculture industry, talc-based mineral solution works as natural alternatives to pesticides for preserving fruit from the sun's rays and diseases. They are perfect for organic agriculture. Talcs are also used to make fertilizer flow and anti-caking agents.
Talc has wide range of applications within several industries. And, our production and supply of talc mineral are innovative and of premium quality. We have been able to cater to the specified needs with our years of technical expertise.
