Product information "Mounted Precision Molded Aspheric Lenses"

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.
