The ELDIM optical laboratory makes high quality optics and complex optical systems for internal needs and subcontracting for more than 10 years. The company has invested in advanced automated technologies both for fabrication, control and mounting.

We process IR, UV and visible materials from single pieces to mass production. ELDIM offers all types of services from optical design to complete fabrication of complex systems.

Aspherical optics
The asphere’s more complex surface profile can eliminate spherical aberration and reduce other optical aberrations compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter than the multi-lens design.

Spherical optics
Spherical lenses, also known as singlets, are transparent optical components consisting of one or more pieces of optical glass with surfaces curved to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.

Plano optics
This is the most common type of lens element. It can be used to focus, collect and collimate light. It is also useful as a simple imaging lens where image quality requirement is not too critical.

Optical coatings
ELDIM can realise different type of filters based on thin dielectric layer stacks (densities, color filters, interference filters) including with custom specifications.
