Knight Optical We can offer Custom Moulded Aspheric Lenses for use with Laser Diode Collimators. Aspheric lens surfaces are used to correct spherical aberration (where the converging light from a lens does not have a common focal point, resulting in a distorted image) in lasers and imaging. Traditional spherical lenses cannot collimate light effectively because even small angles of incidence can produce spherical aberrations. This can mean that several components may be required to get the desired result. The non-spherical surface of an aspheric lens allows a single component to effectively focus or collimate even highly divergent emissions, potentially replacing a multi-lens system with a single aspheric lens. Therefore Aspheric Lenses that are moulded are ideal for use within laser diode-to-fibre coupling applications. For more information read PDF ….

At DLR Elastomer, we pride ourselves on offering a bespoke custom rubber moulding service, understanding application requirements, designing the parts, tooling & process to deliver the product to the clients’ exact and demanding performance needs. Our technical team is happy to advise on materials best suited for your application. Where necessary, we can modify the existing compound and/or develop new compounds keeping the service performance conditions of your product in mind. In addition, we monitor and apply current developments in polymer technology and we use this knowledge to develop even more advanced materials which will benefit our customers. Dlr Elastomer Engineering Rubber component design can be critical to its performance. We offer advice on all aspects of product design, helping to enhance performance & service life. Working from a sample, sketch or drawing, we can quickly select the materials required to provide a quotation for parts and associated tooling.

The well known under-bonnet temperature increase has been resolved mainly by using high-performance polymers with the capability of withstanding temperatures in excess of 200°C. Some of the rubber mouldings commonly encountered in a car include O-rings, seals and grommets. Rubber mouldings are required to resist oils and greases as well as dirt, water, and weathering. Many custom rubber moulding solutions are subject to dynamic loading, including engine mounts and exhaust hangers. Applications requiring the best oil and chemical resistance and good ageing in hot fuel vapours are accommodated using high-performance fluoro (FKM) and fluorosilicone (FVMQ) elastomers. The bonding of rubber to other substrates is a crucial part of being able to offer novel solutions.

Electrically conductive elastomers are made from silicone or fluorosilicone loaded with highly conductive particles such as silver plated aluminium, silver plated copper, nickel coated graphite and pure nickel. “O” rings can be vulcanised or moulded depending on customer's request and needs. Conductive elastomers offer an excellent temperature range and are resistance to compression set whilst fluorosilicone has superior resistance to fuel oils and solvents.
