Abstract
Optical systems are normally usable over a restricted spectral waveband. A refractive optical system will only transmit radiation over a limited range of wavelengths and it may only produce well color corrected images over part of this transmission band. This paper discusses the design of lens systems for use over the extended waveband from about 0.4 microns to 12 microns, which encompasses the visible, the 3-5 micron mid-infrared and the 8-12 micron thermal wavebands. Discussion is given to the available optical materials including glasses formed by chemical vapor deposition and crystalline materials. The relationships between the refractive and dispersive properties required for wide band color correction are formulated and several designs are described which use two and three optical materials. Some discussion is given to the coatings required for such optics viz. ultra-wide band anti-reflection, mirror and beam splitting coatings. The potential use of this type of optical system is in multi-sensor applications such as dual visual/thermal observation systems perhaps employing staring array technology and/or CO2 laser incorporation.
