We offer all digital microscopy camera kits from PixeLink including the new PL-E400 CMOS USB 2.0 cameras (top, at right). That includes the latest kits in the PL-B600 CMOS (middle, right) & PL-B800 CCD series of digital cameras for microscopy (with either USB or Firewire interfaces).   PixeLINK products will provide you with the most value for your high-quality science applications. These cameras and software are tailored to high-productivity image acquisition applications where consistent quality and performance is expected and is an effective solution to any laboratory.   PixeLink's advantage comes from reducing overall system complexity and cost. It has embraced standard computer interface technologies including FireWire and USB, and provides drivers and software on the host computer that effectively eliminate the need for a frame-grabber while enabling advanced camera functionality. PixeLINK µScope Microscopy Software is included with each camera kit. This is a real-time, interactive application designed specifically for microscopy to capture, save, annotate and measure still images.

Our spherical plano-concave germanium lenses are primarily used to diverge a beam from a collimated light source, or to increase the focal length of an optical system. They may be used in beam expanders, and can also be used to balance out aberrations which were introduced by other lenses in an optical arrangement.

Our germanium lenses have a high refractive index—the highest refractive index among readily available IR transmitters. It also exhibits minimal chromatic aberration due to low dispersion. Because of these properties, Ge lenses are ideal for use in infrared (FLIR and FTIR) field applications. Other applications include thermal imaging systems and precision analytic instruments which may be used in harsh environments.

It is the special hardness of germanium that gives it its unique ruggedness; Ge has a Knoop hardness of 780. It is a high density material, at 5.33 g/cm3, and allowances must be made for this weight if you are designing a weight sensitive system.

Germanium is also subject to thermal runaway. What this means is that the transmission will decrease as temperature increases, and the lens becomes opaque. Because of this thermal runaway effect, germanium lenses should only be used at temperatures below 100°C.

Germanium has optimal transmission (over 45%) in the 2-12 μm band, which makes it most useful for mid-infrared light.  With anti-reflective coatings, transmission can be brought up to about 95%.

Plano-convex Ge lenses are flat on one side and convex on the other. These lenses have a positive focal length, and are often used for light collimation. They can also be used in focusing applications, and have widespread use in various fields, from science to industry to defense. We recommend these lenses be oriented so that the flat side faces the desired focal plane.

Germaniumlens for thermal camera

Our aspheric lenses have a more complex front. The curvature gradually changes as you move from the center of the lens out to the edge. Our aspheric Ge lenses are most often used to eliminate spherical aberration in an optical system. Adding an aspheric lens into an optical assembly has the potential to greatly simplify the system, and even the addition of relatively heavy germanium lens may actually decrease the systems weight.

At Shanghai Optics we manufacture a wide variety of germanium lenses with various anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all available in a wide variety of sizes. We are also able to accommodate special orders should you need a size, shape or AR coating.

Shanghai Optics manufactures quality germanium lenses in a range of popular sizes, from 5m m to 350 mm in diameter. Our standard anti reflective coating is best suited for light transmissions between 3 and 12 μm.  The focal length of our lenses is determined up to a +/-1% tolerance, and the surface flatness is l/4 @ 633nm.
