On August 4th, with the sound of firecrackers opened in Guilin Lipu Haohao store, Haohao Lighting blew the horn of entering the Guilin market. According to Wu Changyao, the person in charge of Guangxi Lighting, the next goal of the Guilin store will be to open up the Quanzhou Haohao store. Once realized, the county-level market will develop rapidly. The establishment of county-level specialty stores not only facilitates the purchase of consumers, but also facilitates the circulation of products and the market meeting rate, so that buyers can save a lot of time and cost of purchase, so that the brand effect gradually becomes dewy.

Bi-Concave (Double-Concave) lenses have equal radius of curvature on both sides of the lens and function similarly to plano-concave lenses by causing collimated incident light to diverge.
Double-Concave Lenses are used in beam expansion, image reduction, or light projection applications. These lenses are also ideal for expanding the focal length of an optical system. Double-Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths.
Realpoo Optics offers double concave lens, and they are available in several anti-reflection coating optics, including MgF2, VIS 0°, VIS-NIR, NIR I, or NIR II, for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) regions.
