Cylindrical Lenses
Product Description
Cylindrical Lenses Process Capability
Boxin owns more than 100 sets of CNC cylindrical lens grinding and polishing machines; meanwhile, we also have 40 sets of traditional polishing machines.
In terms of accuracy inspection, Boxin adopts ZYGO laser interferometer equips with diffractive lenses for different radii of cylindrical products. Moreover, for generatrix, perpendicularity, and bevel angle, Boxin has a self-developed a cylindrical lens inspection equipment.
The processing materials for Boxin cylindrical lenses covered Visible Light, Near IR, Far IR, etc. Processing range is extensive, from 2mm to 1200mm in length, and width is up to 650 mm.
Annually, Boxin supplies 2,000,000 pieces of cylindrical lenses to customers worldwide.
