Having Modern Technology Machines
ECOPTIK, formerly BRD Optical was founded in 2004, and is located in the city of Changchun – the optic base of China – with beautiful views and profound optical culture. We have state-of-the-art, modern technology machines for manufacturing and inspecting all kinds of precision optics. Our company occupies an area of 1500 square meters, supported by 42 workers, including three technical engineers and two dedicated optical engineers.
Increasing Production Levels
In the aspect of technology, we benefit from the backbone of Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, and Changchun University of Science and Technology. We also usually make technical exchanges with each other. Referring to the manufacture equipment and checking equipment of products, most of them are adopted from abroad including coating machine, sphericity interferometer, optical spherometer and others. They can detect the optical components exactly and increase the production levels.
Wide Range of Products to Choose From
We comply with a standard of DIN, MIL, ISO surface quality standards in the aspect of production layout and production design. We also focus on manufacturing and selling precision optics with high quality. We mainly deal with high-quality precision
optical components and
optical assemblies. Products include
spherical lenses,
dome lenses,
prisms,
windows, filters, cylindrical lenses, aspherical lenses, mirrors, quartz glass, beamsplitters, wedges, doublet lenses, and more. Customized
optical design. is provided.

Types of Custom Glass Reticles
The precision custom optical glass reticle is generally installed on the focal plane of the right eyepiece of the telescope. It is a thin glass with reticle dense lines engraved on the surface of the pole book. In theory, this thin glass also participates in imaging and extends the focal length of the objective lens, which will have more or less influence on the length of the right eyepiece.
ECOPTIK, formerly BRD Optical is one of the few companies producing custom glass reticles because the reticles require extremely high cleanliness. Any tiny dust will produce large black spots during observation. At the same time, the accuracy of the installation position of the custom glass reticle is extremely high. Therefore, try not to disassemble it. If it is disassembled, it must be as it is recovery.
Dielectric Mirror
A dielectric mirror, also known as a Bragg mirror, is a
type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or some other optical material. By careful choice of the type and thickness of the dielectric layers, one can design an optical coating with specified reflectivity at different wavelengths of light. Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser. Mirrors of this type are very common in optics experiments, due to improved techniques that allow inexpensive manufacture of high-quality mirrors. Examples of their applications include laser cavity end mirrors, hot and cold mirrors, thin-film beamsplitters, and the coatings on modern mirror shades.
Visible Dome
Our transparent glass dome lens is composed of two parallel optical surfaces, (a convex surface & a concave surface). Normally we can control the parallel tolerance <±2 μm. A perfect parallel surface, in the imaging, the image does not distort, and in the measurement of light, the light does not distort.
Optical Dome, the optical properties are unique, which produced by the optical technology of optical grinding and polishing.
ECOPTIK, formerly BRD Optical large clear dome lens mainly are hemisphere, hyper-hemisphere and customized designing. Whether it is visible dome, UV dome or IR dome, ECOPTIK, formerly BRD Optical Dome has been confirmed in the international market. ECOPTIK, formerly BRD Optical dome is found in areas such as defense technology, weather monitoring, and optical imaging.
ECOPTIK, formerly BRD Optical is your customization optics partner.
