Knight Optical offer a range of Stock N-BK7 Precision Grade Windows, for use with Thermal Imagining Cameras. Infrared radiation is characterised by the wavelengths ranging from 750nm to 1000µm. Although typically used for the visible range, N-BK7 does have transmission within the near infrared spectrum also. Where IR materials such as Germanium are limited to a small band in the IR spectrum, N-BK7 works well throughout the entire visible and into the NIR, making it a perfect material for a protective window for using within a Thermal Imaging Camera. A low cost material, it is perfect substrate for your protective window. We can supply both stock and custom N-BK7 windows to protect your thermal imaging application. The high optical quality and uniform transmission of N-BK7 as well as low absorption in the entire visible wavelength range is a key feature for this application. For more information read PDF

The thermoIMAGER TIM QVGA and TIM VGA cameras are used for stationary thermography tasks where high resolution is required. Due to their high thermal sensitivity, these cameras also detect even the smallest of temperature differences. Both standard lenses and special microscope lenses are available for the TIM QVGA and TIM VGA cameras. The microscope lens enables detailed macro shooting of the smallest of elements. High-resolution macro shooting is possible with a spatial resolution of 28 µm. The distance between the target and the camera varies between 80 mm and 100 mm.

We can supply you with a custom made Diamond turned aspheric lenses for use within Thermal Imaging Cameras. Thermal Imaging Cameras work similarly to traditional visible camera systems; while traditional cameras form images using visible light; thermal cameras form images using infrared radiation; operating in wavelengths as long as 14µm. Spherical aberration occurs in common singlet lenses, which results in an image that appears distorted, aspheric lenses correct spherical aberration. An aspheric lens surface is designed non-spherical, which allows a single component lens to collimate or focus highly divergent rays, potentially replacing a multi-lens system. This in turn provides the camera system with a better image quality. Knight Optical offers diamond turned aspherics from a range of infrared materials including Germanium (Ge), Calcium Fluoride (CaF₂), Zinc Sulphide (ZnS), Zinc Selenide (ZnSe), Aluminium (Al) and chalcogenide glasses like AMTIR (Ge33As12Se55 ) PDF FOR INFO
