Concave Reflector Dish with Round Optical Reflector Lens and Concentric Circular Ridges

LED lighting fixtures, scientific research instruments, and semiconductor inspection systems use a round optical reflector lens with concentric circular ridges to control beam divergence and focus reflected light onto the target; ridge pitch and focal depth determine reflector efficiency and the resulting beam profile. Shenzhen Hongda machines this concave reflector dish in Shenzhen using 5-axis milling and CNC milling, with ridge pitch, focal depth, and finish quality Ra class held to your specification. The workshop area covers just under 4,000 m². Clients include automotive, military, and robotics buyers. IATF16949 and ISO 9001 certification at Hongda's Guangdong facility governs machining qualification and dimensional process documentation for aerospace, medical equipment, semiconductor, and lighting industry optical component applications. 5-axis milling handles the concave dish profile and ridge geometry in a single setup without repositioning. Include your drawing with ridge pitch, focal depth, surface finish Ra class, and material specification; our Shenzhen team will return a quotation and lead time.
