The KV-FL1 Multispectral Flash from Kolari Vision is for illuminating your subjects in indoor IR/UV applications, when you use IR or UV filters with a full-spectrum modified camera. The flash unit comes with IR (850nm) and UV flash filters, also referred to as flash cups, which attach to the flash head. When you use the IR flash cup for IR applications, it will make the flash only barely visible to the human eye even on the highest power settings. The UV flash cup reduces the flash to a softer, purple glow.

This speedlight style flash features a standard hot shoe for use on- or off-camera. Clamp-mount focus assist flashlights are included to help with focusing and composing your shot. These flashlights will light your scene in the spectrum that you need, allowing you to see what you're going to get before the flash goes off. This lets you eliminate trial and error. The flashlights attach to the flash via quick release clamp-mounts, allowing for quick and easy swaps for IR and UV applications.

The flash unit runs on four AA batteries. The focus assist flashlights are each powered by a single AA battery. Only two AA batteries are included (one for each flashlight).
