The image intensifier tube amplifies low-intensity UV light by converting photons into electrons and then multiplying them before converting them back into visible light. This results in a brighter and clearer image, especially in low-light conditions.

In general, a UV camera is able to capture an image within UV spectrum where human eyes are incapable to see. The Photonis UV camera stands out from the other cameras because it is equipped with Photonis’ image intensifier tube allowing for a drastic improvement of sensitivity and low-light performance in the ultraviolet (UV) spectrum.

Certainly! Photonis low-light cameras are capable of capturing color images in low-light conditions. It utilizes advanced image processing to maintain color accuracy in low-light settings. Improving the experience to see the color during night. 

The Photonis low light camera can produce a high quality image with a very low dark condition up to Night Level 3 or Quarter moonlight condition (10 mlx). In addition, the Photonis intensified camera is able to capture a high quality image with an overcast starlight condition or Night Level 5 (0.7 mlx)

A low-light camera is a type of digital camera specifically designed to capture high-quality images or video in a very low illumination conditions, where regular cameras may struggle to produce clear and detailed images.

While designed for low-light conditions, Photonis UV features gain control to adapt various lighting conditions, including daylight. However, we strongly suggest not operating the camera with direct sunlight.

Photonis UV cameras suits for applications in fields such as surveillance, scientific research, industrial inspection, and defense, where the detection and analysis of low-light UV signals are crucial.

The choice of lens format may differ for different applications. It depends on the specific requirements of the users, and the resolution of the camera sensor. Higher resolution is generally preferred for applications where detailed imaging is crucial, but factors such as field of view and distance to the target also play a significant role in selecting the appropriate lens. 

The night level is a darkness condition that is usually used in some applications. Below is the list describing the night level with the correspondence unit of illuminance:
Night level 1 : full moon condition, 40-1000 mlx
Night level 2 : half-moon condition, 10-40 mlx
Night level 3 : partial moon, 2-10 mlx
Night level 4 : clear starlight, 0.7-2 mlx 
Night level 5 : overcast starlight, 0-0.7 mlx
 

An active digital camera employs its own source of illumination to enhance visibility in low-light conditions. This camera actively emits additional light and captures the reflected signals. In contrast, a passive low-light camera relies solely on available ambient light, such as moonlight or starlight, without emitting any additional light of its own.
