Infiniti optics provides a wide variety of EO/IR camera solutions all the way from a component level, open frame modules (lens and sensor attached) or as complete integrated PTZ cameras with Visible and SWIR sensors for ultra long range imaging required by a host of military and defense applications.įor more information about thermal infrared imaging for night vision and surveillance see our Thermal Imaging Explained page. Infiniti uses mostly ƒ/1.0 and ƒ/1.1 lenses in our LWIR thermal cameras to ensure high contrast, long-range performance for detection, recognition, and identification When looking at thermal imaging it is very important to look at the lens’s f‑number, as this is often as important the thermal sensor in determining the actual performance of the system. An ƒ/1.0 Ge lens allows for 2.5x more infrared thermal energy to be transferred to the infrared sensor than an ƒ/1.6 lens. This is particularly true for uncooled LWIR cameras where lower f‑number lenses like ƒ/1.0 to ƒ/1.6 are required. The higher the f -stop, the lower the aperture meaning less light will be let into the camera.

#Small f stop series#
Engineered to function with our UL and Mountain Series packs, the f-stop ICU (Internal Camera Unit) protects and organizes your gear. The f -stop is a way of measuring what the aperture of the lens is at. Make sure this fits by entering your model number. This why long range cameras are either thermal or require our ZLID (Zoom Laser IR Diode) Illumination ir order to have night vision.įor thermal infrared cameras, having a lower f‑stop number increases the image contrast and clarity, which results in higher detection distances. A small aperture is a large f-stop number. The lower the f‑number, the better the lens is for visible and NIR imaging, as it results in a system with increased light (or Lux) sensitivity and allows the camera to capture more accurate images in lower light levels, long range cameras like our 135x optical zoom (15.5-2075mm) due to their high power zoom focal lengths have much higher F stop which is why there is no long range low light cameras.
Lenses are typically specified with their maximum aperture ability.Ī low ƒ/# means a larger maximum aperture (also called a fast lens), which results in a higher light or infrared collecting ability while a high ƒ/# means a smaller aperture (slow lens), which has lower light or infrared collecting ability.
#Small f stop iso#
Along with shutter speed and ISO (sensitivity to light), aperture is the third fundamental component that makes up the exposure triangle in photography.
The aperture controls the amount of light that enters the camera lens, and it’s measured in f-stops. An f‑number (ƒ/#) or f‑stop refers to the ratio of a lens’s focal length to its aperture’s diameter and indicates the amount of light coming through the lens. F-stop is the term used to denote aperture measurements on your camera.
