The class of optical filters used to change the correlated color temperature of a light source is called color temperature filters. This article discusses the use of color temperature orange (CTO) and color temperature blue (CTB) filters in particular.
The human visual system has the ability to map “white” colors to the sensation of white, even though an object has different radiance when it is illuminated with different light sources. This app note discusses the use and calibration of white balance, specifically for Allied Vision GigE cameras.
Alluxa’s new precision infrared bandpass and dual bandpass filter technology brings new levels of performance with higher transmissions, steeper slopes, and flatter pass bands than traditional evaporated coatings.
The hyperspectral imager comes with challenges, not the least of which is choosing the right one to use for any given application. That decision depends in part on the user’s requirements, the wavelength range in which the imager will be used, and the intended application.

While IR cameras are nothing new, the latest high-speed variants bring with them new functionality, benefits, and a few limitations. This Q&A seeks to shed light on all the advantages and potential constraints of high-speed imaging and to address some of the key questions often asked about this technology.
FLIR's RS Series is made up of the RS6700, RS6800, and RS8300 instruments in ruggedized enclosures. These MWIR cameras are multi-application, long-range infrared camera systems designed for range tracking, target signature, target edge detection, research, and science applications.
The FCI-InGaAs-XXM series of high-speed InGaAs photodiode arrays are designed with 4, 8, 12, and 16 channels. Each AR coated element is capable of 2.5 Gbps data rates exhibiting high responsivity from 1100 nm to 1620 nm.
The Ninox 1280 offers visible extension from 0.4 µm to 1.7 µm to enable high-sensitivity scientific imaging using a 1280 x 1024 InGaAs sensor. With cooling to -15 °C, the camera achieves typical dark current readings of <2,000 e/p/s at this temperature, allowing for longer exposure times. The 10 µm x 10 µm pixel pitch enables the highest resolution imaging. The camera will offer ultra-high, intra-scene dynamic range of 69 dB enabling simultaneous capture of bright and dark portions of a scene.
