Paper Abstract

To show flames in the visible and low infrared regions of radiation in the wavelength range from 400 nm to 2000 nm a design of optical systems technical borescope is presented. The proposed glass and technical parameters of the optical system correspond to the diameters of the lens elements and their distance of the borescope for VIS only. The correction lengths and distances of images are approximately the same and also correspond to the mechanical construction of the existing borescope for visible light. To record images in the wavelength range from 800 nm to 1000 nm it is possible to use the classic black-and-white cameras, e.g. OSCAR OS-458. Recording wavelengths in the range of 900 nm to 1700 nm allows, for example, InGaAs camera Bobcat 1.7-320.
