LDA050VB Precision Molded Aspheric Lens

Focal Length 1.50-22.00 mm; Numerical Aperture 0.13-0.71; Design Wavelength 405-7800 nm; Outer Diameter 6.24-14.25 mm; Thread MT6, MT8, MT9, MT12, MT14 With 27 of GH Optics’ standard precision molded aspheric lenses mounted into five different stainless steel lens holders, this series of components allow for very easy assembly. Our mounted precision molded aspheric lenses feature MT6, MT8, MT9, MT12 or MT14 threads for screwing the components into your systems, but they can also be soldered or welded to suitable structures in the required position. GH Optics’ series of mounted precision molded glass aspheric lenses can be used for applications in the visible (VIS) and infrared (IR) wavebands, such as small beam collimation, focusing, and fiber coupling. In these applications, aspheric lenses avoid spherical aberrations known from spherical lenses and can therefore reduce the complexity of both the design process and the resulting optical system. While the cost and effort involved in the traditional production of aspheric lenses has often prevented the use of this type of lens in cost-sensitive applications, GH Optics manufactures affordable aspheric lenses with high, reproducible quality by molding glass preforms in molds of high precision. On request, most aspheric lenses in our portfolio can be mounted into a custom assembly specified by the customer. For large-volume applications we recommend to contact your regional AMS Technologies office, so that we can tailor a solution based on your technical needs. Three types of glass are available for our series of mounted precision molded aspheric lenses for visible and NIR wavelenghts, all RoHS compliant: Lens Series Glass Type Refractive Index Abbe Number CTE dn/dT RoHS Compliance MD D-ZK3 1.586 60.71 7.6×10-6/°C 3.2×10-6/°C yes ME D-ZLaF52La 1.806 40.79 6.9×10-6/°C 6.5×10-6/°C yes MG D-LaK6 1.690 52.65 6.9×10-6/°C 6.5×10-6/°C yes   For our mounted precision molded infrared aspheric lenses, two types of chalcogenide glass are available, comparable to infrared glass of other leading brands in the market and featuring high transmission as well as RoHS compliance:  Lens Series Glass Type Glass Material Refractive Index @10 µm Abbe Number @10 µm CTE dn/dT RoHS Compliance M2 GH2 Ge28Sb12Se60 2.6044 93.63 142×10-7/°C 70.4×10-6/°C yes M6 GH6 As40Se60 2.7775 137.71 209×10-7/°C 31.3×10-6/°C yes   Mounted precision molded aspheric lenses for visible and NIR wavelengths can be coated with a range of visible and NIR coatings, including four standard AR coatings (VA, VB, VC, VQ) featuring average reflectance values of ≤0.6%, ≤0.5%, or even ≤0.25%, for wavelength ranges of 380 nm to 700 nm, 600 nm to 1100 nm, 1050 nm to 1650 nm, or 1300 nm to 1700 nm respectively. Other customized coatings like HD (High Density) or SWB (Short Wave Blocking) are available on request.
