Germaniumlens for thermal camera

Also called converging lens because light rays will come together at the focus. There are a couple different configurations that are important.

Our production staff uses precision CNC curve generators to produce best-in-class germanium lenses for any of your requirements — from prototype requests through full production volumes.

In a ray diagram, the solid lines indicate the actual path of light rays. Real images form where the rays converge. On the other hand, dotted lines indicate the path of virtual rays. They form virtual images when they converge.

At Lattice Materials, we custom manufacture germanium lenses with a well-defined and controlled process to ensure that they meet stringent performance requirements:

Lattice Materials is exceptionally equipped to create optical components, and germanium lenses in particular, to precise optical specifications with any finishing you require.

Germanium lenses are optical lenses fabricated from germanium (Ge) primarily due to its unique optical properties — particularly its high refractive index, thermal stability, and infrared transparency.

Manufacturing custom germanium lenses for high-performance optical applications requires expertise in germanium optics, advanced equipment such as CNC curve generators, and highly controlled manufacturing processes.

Light from an object hitting a mirror or lens is approximated by two or three arrows that go towards the top, center, and bottom of the mirror or lens. Since ray diagrams are approximations, we will not need to calculate any specific angles of reflection or refraction.

Depending on the angle, an interesting phenomenon called total internal reflection can occur. Whenever light is moving from a medium of a higher index of refraction to a medium of lower index of refraction, some of the light is reflected back into the original medium. If the angle is greater than the critical angle, all the light is reflected. The critical angle is the angle at which light is refracted at 90° from the normal (along the interface between the two mediums).

Light refracts when it travels from one medium to another (examples: from air to water, from glass to air). Light will change direction when entering a new medium because it will travel at a different speed in the new medium.

Concave mirrors are shaped like a parabola and curve towards the object. One key factor of a concave mirror is that light rays coming in parallel (from an infinite distance) will all come together at the focus. There are a few different arrangements that are associated with concave mirrors. Each one produces a different sort of image.

Lensmaker’s Equation: Allows us to calculate the focal length of a lens based on the material its made of and the curvature of the lens.

The principles of geometric optics describe the interactions of light on a macroscopic scale. Geometric optics is mainly used to determine how light will change direction and form images through reflection or refraction. The path of light is approximated by rays that travel in straight lines. All angles regarding reflection and refraction are measured from the normal, which is a line perpendicular to the surface the light is interacting with.

Also called a diverging lens because the light rays will diverge after passing through the lens. Diverging lenses always form a virtual, upright, diminished image.

Germanium has many advantages, making it a suitable material for fabricating spherical lenses and aspheric lenses for various applications in aerospace, defense, and infrared optics.

Focal Length (Focus): The point where originally parallel light rays converge when they reflect off a curved mirror or refract through a lens.

When light hits a surface, it always reflects away from the object at the same angle that it hits the surface. The angle is measured relative the normal. Depending on the surface, two types of reflection are possible:

Total Internal Reflection: Occurs when the light ray’s incident angle is greater than the critical angle, causing all of the light to be reflected back into the original medium.

Our germanium lenses are used in various high-performance optical systems, particularly in applications that involve infrared imaging systems, remote sensing, and thermal imaging systems.
