Or sizzling places might not appear at wider apertures but show up when you cease down (case in point under.) With zoom lenses, you could possibly get scorching spots at some focal lengths instead of Other folks.
All a few correspond to a particular number of wavelengths inside the IR spectrum, and they are commonly Employed in numerous purposes together with distant sensing, thermal imaging, and spectroscopy.
Our condition of the art MTF Tests allows us to ascertain a substantial list of optical parameters into a large degree of precision, and assure Every of our lenses will conduct as envisioned over a large spectral selection. Our manufacturing facility is also ISO 9001 certified and all of our lenses are analyzed versus ISO and Mil requirements.
