SWIR Fixed Focal Length Lenses

SWIR Series Fixed Focal Length Imaging Lenses are compact, lightweight lenses designed for applications operating. Shortwave Infrared (SWIR) wavelength band ranging from 0.9 – 1.7μm offers unique imaging advantages over visible and other thermal bands. These lenses feature SWIR-optimized optical designs, glass types, and AR coatings from 0.8 – 1.8μm. Designed for high throughput and superior performance, the SWIR Series lenses are commercial-off-the shelf (COTS) lenses with low f/#’s, covering large 25mm sensors.

SWIR Imaging Equipment

Short Wave IR (SWIR) lenses provide a crisp image over the full zoom range, with MTF close to the diffraction limit. Providing outstanding detection, recognition and identification (DRI) ranges. SWIR Series Fixed Focal Length Lenses is quietly earning a growing place in industrial machine vision for electronic board inspection, material/food sorting, solar cell inspection, quality inspection, and in military applications. SWIR lenses are suitable for a wide range of commercial, surveillance and homeland security applications. SWIR lenses are utilized where other detectors or cameras are not sensitive enough for finite detail recognition.

Advantages

SWIR Lenses designed for InGaAs SWIR camera technology, and compatible lenses are widely available from commercial vendors. Get features like broad wavelength bands, large sensor areas, varying focal lengths, and working distances that enable brilliant imaging from your camera and lens combo.

SUPERIOR is capable of designing and manufacturing SWIR lenses with the best optical performance on the market. These lenses can be produced in a variety of sizes, focal lengths, and fields of view to meet the customer’s needs.

Applications

SWIR cameras with SWIR Fixed Focal Length Lenses are used in a variety of applications in industry and research, ranging from inspection, quality control, identification, detection, surveillance, etc. They have applications in the inspection of food/products, solar cells, circuit boards, and counterfeit.

Inspection: While silicon electroluminescence occurs in the SWIR spectrum, silicon-based CCD or CMOS image sensors are unable to measure SWIR spectrum energy. Similar to how applying a voltage across an LED will light the LED, applying a voltage across silicon-based solar cells will illuminate the cells. This feature is useful for solar cell inspection.

Military Surveillance: Because of its longer wavelength, SWIR is less affected by the Rayleigh scattering effect and this enhances visibility. SWIR travels through largely unscattered, whereas small particles (haze, smoke, etc) scatter visible light. The main benefit of improved long-range visibility in surveillance applications over visible light cameras is the capacity to see through the haze.

Remote Sensing: The SWIR spectrum is famous for its sensitivity to moisture in remote sensing applications, which can be connected to significant metrics like leaf water content and other physiological states of crop canopies.
