Davin works with a worldwide base of defence, security and commercial Clients.

Davin designs and manufactures lenses and optical solutions for thermal imagers in both the 3-5µm and 8-14µm thermal imaging bands. This is a core competence of the company evidenced by a substantial portfolio of successful Client projects in both military and commercial applications.

Davin Optronics has extensive experience and expertise in the design and manufacture of thermal imaging lenses for both industrial and defence applications. We have a range of thermal imaging lenses for use with modern staring array sensors in both the 3-5µm and 8-14µm bands and with performances optimised for pixel dimensions from 50µm x 50µm down to the most recent devices at 17µm x 17µm. Our advanced designs use aspheric and diffractive surfaces when required to provide the best and most economic design solutions.

We also have experience in designing and manufacturing solutions that are sealed, ruggedized and fully qualified for defence, security and aerospace applications Recognising that athermalisation has become increasingly important to the designers and users of thermal imagers in industrial, security and defence applications, Davin has developed a number of passively athermalised lenses that offer stable imaging performance over the temperature range of -30°C to +60°C.

The thermal imaging optical components and lens systems are manufactured, assembled and tested at our Watford facility. Qualification of imaging lenses is by the measurement of MTF on our all-band MTF test equipment. When required, systems may be further qualified by shock and vibration testing at an accredited test house.

We also manufacture optical components for infrared systems to customer drawings. These components can be supplied fully qualified by measurement, interferometry, defect standards, coating performance etc. and full material traceability can be supplied.

Athermalised Thermal Imaging Lenses

Davin Optronics offers a range of high performance, ruggedized and athermalised lenses for uncooled focal plane arrays operating in the 8-14µm waveband.
