APPLICATIONS

Biconcave Lenses/Double- concave lenses are manufactured with both concave surfaces. They have negative focal lengths. These lenses are often used to expand light or to increase focal lengths in existing systems. Also, they can be used in laser beam expander, optical character readers, viewers, and projection systems.

Besides standard optics , customized optics is also available. We focus on optical design, optics processing, coatings, electronics& mechanics and the whole optical system integration. Our powerful and professional R&D team guarantees our products a reputation of innovation, quality and high performance.

1)Brilliant Technology is dedicated to being the leading provider of optical components and integrated optical inspection devices with high standard quality control. This goal will be achieved through our focus on the raw material selection, manufacturing process inspection, sampling,finalization and transportation monitoring.

2) During the manufacturing and sampling procedures, precious optical devices shall be used on the optical parameter detection such as surface irregularity, surface scratch,refractive index, coating and etc.

3) Not only optical components were strictly selected, but also the integrated devices. Every module will be under a series of spec run before releasing itself. Evaluation report comes along with the in-house test for the insurance of each devices’ regular working.
