The Right Filter Is Key To Lower-Cost And Faster Time-To-Market MWIR Equipment
Article | By Jason Palidwar and Peter Hook, Iridian Spectral Technologies

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.

OEMs: Expand Your Product Portfolio With sCMOS Sensors
Article | By Scott Metzler, Ph.D., PCO-TECH Inc.

OEMs can enhance their products with expanded capabilities and attract customers by incorporating scientific CMOS sensor technology.

Math, Magic And MTF: A Cheat Sheet For The Vision System Community
Article | Schneider Optics

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.

SWIR Camera Utilized In Cutting Edge Tornado Research
Case Study | Sensors Unlimited – A part of Collins Aerospace

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. 

Neutral Density Filters
Catalog | HOYA Corporation USA Optics Division

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.
