SWIR Cameras and Accessories in Photovoltaics

At that glass inspection stage, rejects are identified, then shunted aside and reprocessed efficiently, greatly reducing scrap. SWIR cameras can detect the imaging quality of laser spot in the industry，like detects the centroid energy of the spot. whether the laser spot meets the gaussian distribution and other purposes allowing operators to inspect both the interior and exterior walls of the bottle, as well as monitor the temperature uniformity and cooling rate of the material.

 Objects may be the same color in the visible, but outside the visible wavelength band, their reflective properties can be very different. This enables SWIR cameras to detect the contaminants and allow systems to remove them from the processing line.

This SWIR camera independently developed and designed by GHOPTO has a resolution of 640×512, 15μm pixel pitch, and is equipped with a USB3.0 interface. It can achieve a high frame rate of 240fps and 14-bit digital output at the resolution of 640×512. Windowing (optional) realizes higher rate picture transmission. The camera has TE Cooler built in and lower dark current, and the readout noise is as low as 40e-. In addition, the camera has a variety of gain modes and non-uniformity correction, which can improve high-definition images in low light conditions at night, and can also image through fog and haze. Small in size and light in weight, it is easy to integrate in surveillance systems such as drones, shipborne, and airborne optoelectronic pods. It is widely used in wafer inspection, surveillance, hyperspectral imaging and other fields.
