Midwave infrared (MWIR) light is important in many hardware applications, and optical filters are critical to success. Some simple practices can help avoid over-specifying filter characteristics and driving up costs.
MTF is the best proxy for lens performance, but the math behind it and the graphs that depict it often obstruct understanding. This paper demystifies MTF, arming vision system decision makers with the knowledge they need about it to choose the right lens every time.

A team of researchers at Purdue University’s Earth, Atmospheric, and Planetary Sciences Department recently tested the practicality of using shortwave infrared (SWIR) imaging for improving the detection of poorly visible tornadoes in supercell thunderstorms.
Hoya’s neutral density filters have nearly even spectral transmittance in the visible region and are classified by the average transmittance within wavelengths from 400 nm through 700 nm. These filters are able to control light intensity without selectively absorbing light with a specific wavelength.
Canon USA has developed laser rotary encoders that can provide 81,000 pulses with a 36 mm diameter by using the light-diffraction interference method in conjunction with a semiconductor laser acting as the light-emitting element.
