General Introduction: Aspherical concentrator lenses are single lenses whose focal length varies with wavelength. Aspherical concentrating lens is a lens for lighting sources, not an aberration-free lens for laser concentrating. Since the lens is not coated with anti-reflection film, there is reflection loss on both the front and back of the lens, so the transmittance is below 90%.
Features: 1. Aspheric surface can reduce spherical aberration 2. Better radius of curvature 3. Good aberration correction 4. The economic choice of collimating or focusing light 5. Visible or near infrared antireflection film 6. High precision & high surface roughness 7. Sizes can be customized as per the customers' request 8. Quick lead time and delivery time.
Payment Method: by T/T or Western Union. Delivery time: 7-10 days. Quality Warranty: Ruitaiphotoelectric(Raytekoptics) offers quality warranty for our optics products with "3R" policy.
