This category covers:
Instruments and devices used by engineers to determine the scope, quantity or extent of a particular item; to assess that it meets certain criteria; or investigate whether it is in proper working order. Includes environmental testing, vision, sound and vibration testing, position and proximity testing, force strain and speed testing, electrical testing, non-destructive testing and metrology systems.
FLIR Systems has introduced UltraMax technology for its Tsc series of handheld research and science cameras. With the new UltraMax feature, researchers will be able to further improve the resolution of native thermal images for even greater clarity and a higher level of temperature measurement accuracy.

Spatial resolution is also known as the instantaneous field of view (IFOV) or spot size. The limitations of the spatial resolution are due to the size and expense of the focal plane array (FPA). The FPA of many moderately priced cameras will have an array of 320 x 240 or 160 x 120 detectors. As IRISS explains here, this may make it difficult to determine the temperature of small targets at a long distance.
This paper from Renishaw describes the operational principles behind Renishaw’s interferometric angular optics and how they can be used to measure pitch or yaw errors in a linear axis, the angular accuracy of a rotary axis or surface flatness. It examines the various error sources that can affect the accuracy of measurement and the angular optics hardware options available from Renishaw, and how they have been optimised to address these error sources.
Manufacturers have used infrared (IR) windows in motor control centres (MCCs) and electric switchgear for more than two decades. This Tech Byte from IRISS presents some of the IR lens materials that are used.
This paper describes the operational principles behind Renishaw’s XR20-W rotary-axis calibration system and how it can be used ‘on axis’ to calibrate axes of rotation. It examines the various error sources that affect the accuracy of measurement and describes how the system has been designed, and should be used, in order to minimise such errors. It concludes with a section describing how the XR20-W system can be used ‘off axis’ to calibrate fourth and fifth axes on CNC machines.
Fragility increases proportionally to the ratio of the diameter to thickness. If thickness stays the same as the diameter increases, so does the fragility factor. This Tech Byte from IRISS explains how to calculate the minimum thickness of a window required to withstand a pressure difference.
According to IRISS, it is vital that you understand emissivity and how to set-up your thermal imaging camera. In this technical article, the company offers a simple way to check the transmission rate of any infrared window, which it calls ‘the coffee cup test’
The answer is no. As IRISS explains in this Tech Byte, no infrared (IR) viewing pane or individual component can ever be arc rated or protect you from an arc flash explosion. Arc flash explosions have the potential to produce a shock blast of up to 700 miles per hour with a core temperature of up to 15,000°C. Currently, there are no infrared viewing pane lens materials that can resist these extreme levels of temperature or force.
Tech Byte: know your emissivity download
The material emissivity is the relative power of the material’s surface to emit heat by radiation. Materials are assigned an emissivity value between zero and 1.0. Emissivity is a measure of a material’s ability to emit infrared energy. As IRISS explains here, the emissivity of a surface is the ratio of the energy radiated from it to that from a blackbody at the same temperature, the same wavelength and under the same viewing conditions.
