Company Description

Ecoptik (also known as BRD Optical) was founded in 2011, and is located in the city of Changchun-the optic base of China with a beautiful view and profound optical culture. We have state-of-the-art, modern technology machines for manufacturing and inspecting all kinds of precision optics. Ecoptik occupies an area of 3200 square meters, supported by 120 workers.

Concerning 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 benefit from the technical exchange with those experts. Most of the manufacturing equipment and checking equipment of products are adopted from abroad including coating machines, sphericity interferometers, optical spherometers and others. This machinery allows to precisely characterize optical components and establish efficient production.

We comply with a standard of DIN, MIL, or ISO surface quality standards in production layout and production design. For many years, we were focusing on manufacturing and selling precision optics with high quality. We mainly deal with optical lenses, prisms, windows, filters, cylindrical lens, aspherical lens, mirrors, quartz glass, ZnSe, CaF2 and others.

We are very strict with quality, control the delivery time and optimize the service. Our purpose is to satisfy the requirements of our customers, reach their satisfaction and win their trust. At the same time, we welcome our friends in China and abroad to cooperate well and establish a good future together.



Ecoptik has the following distributors:

Product categoryEncDescription
achromatic opticsS Eachromatic optics from Ecoptik

Ecoptik offers achromatic coated lenses which are used to minimize spherical and chromatic aberrations. They are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. Such a lens is often made by either cementing two elements together or mounting the two elements in a housing.

The achromatic coated lens can also be called an achromatic doublet lens or achromatic cemented lens. If you want to know more information, please contact us.

anti-reflection coatingsS Eanti-reflection coatings from Ecoptik

Ecoptik can produce single-layer or multilayer anti-reflection coatings on various kinds of optical elements, using different materials. We achieve reflectivities <0.2% or even better at many wavelengths from 355 nm to 1550 nm, and <0.5% at 284 nm or 193 nm, for example.

We also offer dual wavelength AR coatings, e.g. for 532 nm and 1064 nm.
