optical germanium lenses Options

Plano-convex Ge lenses are flat on a single aspect and convex on one other. These lenses have a positive focal duration, and in many cases are useful for light-weight collimation.

Earlier mentioned benefit are generic requirements for fabrication, particular improved value can be readily available and have to be reviewed circumstance by situation.

Depend upon our gifted crystal development specialists to overcome these issues and provide demanding requirements.

Germanium retains the substantial ground In regards to transmission selection acquiring that added coverage from 7-16µm, which silicon lacks. On top of this, germanium has greater electrical conductivity rendering it a far more suited applicant as an optical element in laser methods.

They can also be Utilized in concentrating purposes, and possess widespread use in many fields, from science to market to protection. We endorse these lenses be oriented so that the flat side faces the desired focal aircraft.

An additional similarity is that anti-reflective coatings might be placed on both of those visible light-weight camera and IR digicam lenses to enhance general performance by minimizing the loss of light and Electrical power that will replicate from the surfaces in the lens if there was no optical coating.

Grinding and polishing: The Preliminary shaping of the germanium substrate using precision grinding and sprucing is vital to get a smooth and uniform surface. A number of methods get more info are followed, Each individual with progressively finer abrasives, till we achieve the specified surface area complete.

Specialised measurement and inspection: Making use of specialised measurement resources and inspection products, we ensure that the surface area roughness, curvature, together with other critical parameters satisfy rigid tolerances and excellent standards.

A broad-angle lens expands your thermal digital camera lens’ area of view. In order to see far more of what’s surrounding an asset, or are Functioning in a good Place, they are mission vital to have the shot.

Ge lenses can transmit infrared wavelengths without having important reduction, allowing for for clear and accurate imaging.

The sharp transmission Slice-off ahead of 2µm also permits germanium for use as an extended go filter, only transmitting wavelengths in surplus of 2µm and fully blocking all the things in advance of it.

I consent that JENOPTIK AG or maybe the Jenoptik Team business answerable for my ask for may perhaps process my e-mail deal with and my other personalized facts entered during the Get in touch with type in an effort to Get hold of me by e-mail, phone or usually and send out me info on services made available from the Jenoptik Team.

Raw germanium content is rather tough but can even now correctly be machined and polished into optical components:
