The handheld Pulsar Quantum HD50S thermal imager has been designed for day and night observations, in conditions where ordinary binoculars and even night vision devices turn out to be ineffective.
Unlike the Pulsar Quantum HD38S thermal imager, the Pulsar Quantum HD50S thermal imager has a longer focal length lens, which translates into a 33% increase in magnification from 2.1 to 2.8x. Now it is possible to detect a target from a distance of up to 1200 m! The new lens also increases the detail of the image, which makes it easier to recognize the target at a distance of 50-150m. In addition, the image noise refresh method is realized by the use of an electronic shutter. The user can choose one of the three image calibration modes - automatic, semi-automatic or manual mode. The Imager offers the same predefined image modes as the HD38 S:
forest mode
target identification mode
city mode
In each mode, the device adapts the image display algorithm to the specific application.
This thermal imager can detect objects in difficult weather conditions, in fog, in smoke, and even hidden behind obstacles such as thickets. The basic elements of the device are a microbolometer with a resolution of 384 x 288 pixels, a germanium lens with a focal length of 50 mm and a frost-resistant OLED display with a resolution of 640 x 480 pixels. The magnification of the Imager is 2.8x, and it can be expanded up to 5.6x (digital zoom). This is the highest magnification in thermal imaging that is available to a civilian user, such as a hunter! In addition, as the only manufacturer on the market, Pulsar provides a refresh rate of up to 30Hz in its thermal imaging devices, enabling the observation of rapidly moving objects.
The Quantum series of Pulsar thermal imaging devices is an alternative to much more expensive competition devices, using the same microbolometers with the same optoelectric parameters. It starts in less than 10 seconds, and turns off as soon as the power switch is pressed. It is light, durable and handy, and easily fits in a jacket pocket. Calibration of the microbolometer is performed immediately during the observation, with a dedicated button on the housing.
Another important advantage of the Pulsar is the perfect viewfinder, using the new generation OLED display. Its advantages will be appreciated by users working in night conditions, where the standard backlight of the LCD matrix greatly reduces the contrast, displaying the black color as gray and impairing the eye's adaptation to night vision. The advantage of the OLED matrix also applies to work at negative temperatures, which negatively affects the speed of refreshing the LCD viewfinder image and in extreme cases leads to complete image immobilization. Pulsar is fast and intuitive, it is ideal for a dynamic environment and can be used in all weather conditions.
The principle of image formation in thermovision is based on the detection of temperature differences in the observed objects, which "shine" in the far infrared range (thermal radiation penetrating all air pollutants and fog). After processing, the image is transferred to the OLED display where it can be presented in the "White Hot" or "Black Hot" mode (the selection of the mode allows you to determine whether warmer objects are presented in brighter or darker colors) .
All controls are located in easily accessible places on the top surface of the case. The buttons are large, they allow you to operate the device with gloves on. The Imager has sockets - a power socket and a video output socket that allow you to record images on external devices. The image is free from distortion and vignetting. The equipment is adapted to work in temperatures ranging from -20 to +50 degrees. The housing is made of carbon fiber and covered with rubber. There is a Weaver rail on the body that allows you to connect additional accessories. forestry

Due to the physics of the operation of the microbolometer, Pulsar Quantum thermal imaging devices are divided into several categories, according to the following system:
Hxxx - high refresh rate 30 Hz, medium sensitivity and low tonal dynamics. Perfect for observing dynamic, rapidly changing environments.
Lxxx - low refresh rate 9 Hz, high sensitivity and high tonal dynamics. It perfectly shows tonal gradation and easily detects subtle differences in the thermals of static scenes.
xDxx - high resolution 384x288 pixels microbolometer, 2x digital zoom available, thermal imager for advanced tasks.
xSxx - low resolution 160x120 pixels microbolometer, without digital zoom, economic, basic version of the thermal imager.
xx19 - 19 mm lens for a wide field of view, together with a high resolution "D" bolometer, it gives an image reproduction ratio of 1: 1 and a large field of view (diagonal of the image 35 degrees).
xx38 - a lens with a focal length of 38 mm for a large detection range, together with a low-resolution "S" bolometer allows to achieve a 5x magnification and a human detection range up to 900 m. • detector: uncooled microbolometer UL 03 16 2

>> FREQUENTLY ASKED QUESTIONS << Question : What is the difference between a night vision device and a thermal imager?
Answer: The night vision device enhances the visible light (380 - 780 nm) and the light that is slightly near infrared. The thermal imager is sensitive to electromagnetic waves of greater length, of the order of a few - several µm, that is several dozen times greater in length. The EM waves, which a typical thermal imager is sensitive to, correspond to thermal (thermal) radiation. The night vision requires light that can amplify (that's why in full darkness we need IR emitters), the thermal vision device also works in complete darkness, in fog, smoke, etc. The advantage of night vision, apart from simply different imaging and in connection with with this different perception of detail, there is higher resolution and lower price. The advantage of thermovision is work in all conditions and easy detection of heat sources, which is of fundamental importance in rescue, and is useful, among others. Hunting, property protection, sea navigation, nature observation.
