Shortpass Filters, also known as "IR-cut" filters, are specially designed to pass a broad spectrum of visible shorter wavelength light, while blocking longer interfering near-infrared wavelengths. Shortpass Filters are typically found over the image sensor in color cameras to block near-infrared light, which helps achieve natural color rendition.
When protecting your camera sensor from a laser, it’s important to choose a filter that blocks with absorption rather than reflection.
