High Performance Athermalised Optical Systems

Company News Thursday, July 10, 2014: EngNet - Engineering Network

Resolve Optics offers a design and manufacture service for organisations looking for top quality, high performance lenses able to reliably undertake sensing, detection and measurement applications at high temperature.

Resolve Optics has considerable experience of developing optical systems that will operate up to 950°C without the need for cooling. Lenses capable of operating at such high temperatures, without degradation, have made it possible to remotely inspect the inside of an operating furnace / boiler and non-invasively analyse high temperature processes including incineration, recycling, smelting and chemical manufacturing.

Optical systems for high temperature applications need to be carefully designed to ensure performance is maintained at the application operating temperature. When materials heat up there is expansion. The rate of expansion differs depending on material types.  To avoid the optical system going out of focus as it reaches operating temperatures – engineers at Resolve Optics take careful consideration of the rate of expansion of components and air spaces.  Temperature also affects the refractive index of materials so this needs to be taken into account as well. Drawing upon 20 years of experience – Resolve Optics has a proven track record of producing lens designs where athermalisation of the optical systems ensures that top performance is maintained over a given temperature range. 

Resolve Optics has developed the rare capability to produce small production quantities of high performance, mounted lenses with the professional look, feel and quality equivalent to the best professional photographic and broadcast TV lenses. Over the last 20 years, Resolve Optics Ltd. have developed market leading applications expertise in a range of areas - most notably industrial machine vision, aerospace, broadcast TV, instrumentation, security and the nuclear industry.
