The Pulsar Quantum HD19S manual thermal imager has been designed for day and night observation, in conditions where ordinary binoculars and even night vision devices turn out to be ineffective.
Unlike the Pulsar Quantum HD19 Imager, the Pulsar Quantum HD19S has a modernized optoelectronic unit and a modified lens construction resulting in increased detail and image quality. In addition, the way of refreshing the image by changing the electronic shutter has been changed. The user can now choose one of three modes - automatic, semi-automatic or stay in manual mode. Another improvement is the changed user menu, in which there are available predefined picture modes:
target identification mode
In each mode, the device adjusts 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 bushes. The basic elements of the device are a microbolometer with a resolution of 384 x 288 pixels, 19mm germanium lens and a frostproof OLED display with a resolution of 640 x 480 pixels. The magnification of the Imager is 1.1x and can be increased to 2.2x (digital zoom). The frequency of image refreshment is up to 30 Hz, allowing you to observe fast-moving objects.
Pulsar's Quantum Thermal Imager series is an alternative to much more expensive competition devices, using the same microbolometers with the same optoelectronic parameters. It starts in less than 10 seconds, it switches off immediately after pressing the power switch. It is lightweight, durable and handy, easily fits into the pocket of the jacket. Calibration of the microbolometer is carried out quickly during the observation, with a dedicated button on the casing.
Another important asset of Pulsar is, among others, an excellent viewfinder that uses the next-generation OLED display. Its values ••will be appreciated by users working in night conditions, where the standard LCD backlight undervalues ••the contrast, displaying the black color as gray and disabling eye adaptation for night vision. The predominance of the OLED matrix also applies to working at a negative temperature, which has a negative effect on the refreshment speed of the LCD viewfinder image and in extreme cases leads to complete immobilization of the image. Pulsar is fast in operation and intuitive, it works perfectly in a dynamic working environment and can be used in all weather conditions.
The principle of image formation in thermal imaging is based on the detection of temperature differences of observed objects that "shine" in the far infrared range (heat radiation penetrating all air pollutants and fog). After processing, the image is transferred to the OLED display where it can be presented in "White Hot" or "Black Hot" mode (the mode selection allows you to specify whether the warmer objects are presented in lighter or darker colors).
All controls are placed in easily accessible places on the upper surface of the housing. The buttons are large, allow you to operate the device with gloves. The Imager has sockets: a power outlet and a video output socket that allows you to record images on external devices. The picture is free from distortion and vignetting. The equipment is adapted to work in temperatures from -20 to +50 degrees. The housing is made of carbon fiber and covered with rubber. The Weaver rail is placed on the body, allowing additional accessories to be connected.
The Pulsar Quantum thermowells, due to the physics of microbolometer operation, are divided into several categories, according to the following system:
Hxxx - high frequency of refreshment 30 Hz, average sensitivity and low tonal dynamics. Ideal for observing dynamic, fast-changing environments.
Lxxx - low refresh rate 9 Hz, high sensitivity and high tonal dynamics. It perfectly shows the tonal gradation and easily detects subtle differences in the temperature of static scenes.
xDxx - high-resolution microbolometer 384x288 pixels, 2x digital zoom available, thermal imager for advanced tasks.
xSxx - micrometer low resolution 160x120 pixels, no digital zoom, economical, basic version of the Imager.
xx19 - lens with 19 mm focal length for wide field of view, together with the high resolution "D" bolometer gives a 1: 1 image reproduction ratio and a large field of view (35 degree image pitch).
xx38 - 38 mm focal length lens for a long detection range, together with the "S" low resolution bolt, allows you to achieve a magnification of 5x and a range of human detection up to 900 m.

Question : What is the difference between a night vision device and the thermal imager?
Answer: Night vision enhances visible light (380 - 780 nm) and slightly near infrared. The thermal imager is sensitive to electromagnetic waves of greater length, on the order of a few or a dozen microns, that is, several dozen times longer. EM waves, to which the typical thermal imager is sensitive, correspond to thermal (thermal) radiation. Night vision requires light that can strengthen (that's why in the dark we need IR radiators), the thermal imager also works in total darkness, in fog, smoke, etc. The advantage of night vision, apart from simply other imaging and in connection with this other perception of details is higher resolution and lower price. The advantage of thermovision is to work in all conditions and to easily detect heat sources, which is of fundamental importance in rescue, and is useful, among others hunting, property protection, sea navigation, and natural observation.
