GlassStructureIR spectrumAbsorption bandCoordination of ionsWe have used IR spectroscopy to study the structure of tellurium germanate glasses synthesized in the system TeO{sub}2-GeO{sub}2-B{sub}2O{sub}3-PbO. The structure of the glasses consists of [BO{sub}3], [BO{sub}4], [GeO{sub}4...
IR X-Ray Vision meets many application needs in such diverse applications as security, surveillance, forest survey, documents inspection and camouflage detection. Kaya Optics produces IR X-Ray Vision glass/gelatin filters and camera systems that see beyond the visible wavelength spectrum. ...
This glass is particulaly useful for cameras and sensors that operate up to 8-11μm. Furthermore, it is less expensive than crystals of germanium, etc., which are widely used at present. IIR-SF®2 is the improved material based on IIR-SF®1. Transmission area is 1 µm longer tha...
IR transmission spectra of phosphosilicate glass (PSG) films with 8 wt.% P prepared by plasma-enhanced chemical vapour deposition (PECVD) and CVD are compared. The differential IR spectrum of a PECVD PSG film differs from that of a CVD PSG film: the P O peak has a lower intensity than ...
An IR reflectance spectrum is defined as the spectrum obtained by measuring the reflection of infrared light from a sample using techniques like ATR or specular reflectance. This method is preferred for samples with smooth, reflective surfaces and requires minimal sample preparation compared to transmitt...
Nearly all CMOS image sensors have at least some sensitivity in the near-infrared spectrum. Because of this, an indispensable component in modern imaging technology, the IR-cut filter, also called an infrared cut-off filter, can block infrared (IR) light while permitting visible light to pass ...
For many camera applications, Infrared (IR) is an unwanted component of the light spectrum and is often blocked using IR cut-off filters that block the transmission of the infrared while passing the visible (VIS). TheSunex IRC4xfamily of dual-bandpass filters on the other hand are specifically...

“With Optris we have a very wide spectrum of different devices, so that we are always able to select the optimum resolution and the appropriate lens.” Kirsten Köhn CEO, IRIS GmbH “There are lots of benefits of using the optris CT LT22 ...
For each simulation under sweep parameter with respect to the wavelength from 650 to 1000 nm, then the phase spectrum was obtained. We linearly fit the phase spectrum of each element to obtain the group delay. To improve the achromatic performance, the achromatic metalens elements should have ...
