Molded Aspheric Lenses LightPath’s glass molding technology has enabled high volume production of aspheric optics while maintaining the highest quality at an affordable price. Because molding is the most consistent and economical way to produce aspheres in large volumes, LightPath has perfected this method to offer the most precise aspheric lens available. LightPath offers standard and custom-made lenses, all designed by our expert optical design engineers. Benefit from the quality and performance of all-glass aspheres Easily transition from prototype phase to high-volume production Customize to fit your application or choose from over 100 standard aspheric designs RoHS-compliant, ultra-high quality glass View Brochure Molding Process 1: Raw materials in ampoule 2: Ampoule added to the furnace to create boule for slicing and coring Geltech Asphere Performance Parameters Search: Lens Code Focal Length (mm) Numerical Aperture Outer Diameter (mm) Working Distance (mm) Drawing 355104 0.3 0.65 1.6 0.150 / .975 Download 355631 0.39 0.55 / 0.13 1.20 x 1.20 0.284 / 1.902 Download 355070 0.43 0.06 / 0.66 1.20 x 1.20 5.00 / 0.270 Download 355485 0.55 0.50 / 0.10 1.00 0.30 / 3.030 Download 355487 0.55 0.50 / 0.11 1.00 0.276 / 2.940 Download 355465 0.55 0.50 / 0.10 1.0 x 1.0 0.250 / 2.874 Download 355536 0.60 0.60 1.24 0.22 Download 355880 0.70 0.60 2.50 0.33 Download 355840 0.75 0.47 3.00 0.43 Download 355915 0.80 0.12 / 0.50 1.30 3.931 / 0.669 Download 355960 1.00 0.62 1.824 0.24 Download 355198 1.05 0.5 1.4 0.610 Download 355200 1.14 0.43 / 0.124 2.40 4.81 Download 355201 1.14 0.124 / 0.430 4.93 1.129 / 4.809 Download 354450 1.16 0.30 / 0.30 1.80 1.67 / 1.67 Download Showing 1 to 15 of 74 entries PreviousNext Standard Coatings LightPath offers a variety of multilayer broadband coatings to reduce the back reflection from a nominal 6% for uncoated lenses. The choice of which AR coating is appropriate depends on the type of glass the lens is made from and the wavelength at which the lens will be used.
