Top Lens and Window Secrets

Because of the dependence of our thermal emission characteristics on the thermal wavelength, only a few wavelengths are suitable for thermal measurements. The following diagrams illustrate the ranges of thermal transmission of common thermal lenses and window materials for infrared thermometers. The blue-colored curve reflects the general rule that applies to all materials. It is the average value over a temperature range of zero (black), infinity (green) and is the cold-pressure limit (CPL).

The cold-pressure limit, which is used for lenses and windows is the highest recorded value of a material’s damping rate against the thermal gradient. This ratio is plotted as a function the temperature variation across the viewing angle for a given viewing angle and the cte of the lens or window. The bending moment of a system is the change in the angle of incidence, which is spherical or linear. This results in the slope being proportional to this curve. The slope of this curve is also proportional to the focal length of the system, which is considered as a function of the focal length divided by the period of the curve (i.e. the period between shots).

For a particular temperature range and a given focal length of a window or lens assembly, the inside temperature of the system will always fall within the prescribed curve , in the perfect order known as a “curved surface.” The thermal conductance curve of a glass beads inside a glass vial may be plotted in relation to the focal length as well as the temperature difference between the bottom of the vial and its surface and the angle of incidence of a given window. If the aperture is fixed for all shots, then the area between the system’s surface temperature and the curve of variation must remain constant. If the aperture is adjustable and the curve is not fixed, then it could be curved as a result of the variations in the temperature of the glass used in the making of the bead, the temperature of the ambient atmospheric air on the inside of the vial’s surface, and the focal length and time of shooting. An example of a curved surface can be seen in the signature of a photographer of the flower.

The mounting of a window and lens must be done to ensure that their focal points, and lines of sight, are correct. If the temperature of the inside of the system is too cool for the lens, then the outside surface temperature of the frame will be cooler and the interior temperature of the lens will be too hot. If the temperature outside of the lens and the frame are the same, then the frame will not require any adjustment to counteract the heating or cooling effects of internal temperature differences. If there aren’t any temperature differences from outside, the frame’s inside temperature will be the same for a given focal length. If the system is located in an area with restricted or blocked views of the surrounding structures or landscape it might be necessary to regulate internal temperatures.

The first mechanical interlocking system used to mount lenses to cameras were made of plastic or other materials that would change shape or bend in response to changes in mounting pressure. This design was later used to create pinhole glasses. A problem with this type of lens assembly is that the mechanical joints between the lens and frame might indent or even fracture. In the event of this occurring, it would be essential for the entire system to be replaced within the shortest amount of time. Because of this issue the type of system has been replaced by more robust designs.

Lenses that are designed for use with pinhole glasses typically have frames made of metallic and a thin plastic or glass lid. At a minimum the lense designs should include a hermetically sealed lens construction. A lens that is hermetically sealed has a sealed surface at the bottom and the top. The top surface could contain an electronic seal that is similar to that described above. It could also contain an lip, adhesive or a layer of plastic film.

Another variation of window and lens assembly is a lens surface that contains an adhesive that adheres to the base of the window assembly. This kind of system usually consists of a window casing and several compartments for lenses. The windows could also include other types of devices, like light emitters, or thermometers. In some cases, the device that controls the temperature within the room might also be part of this type of system. In this scenario the system would comprise of compartments that could be used to house the temperature controller along with a number of other devices, like an alarm thermostat or clock.
