Pulsar Quantum Series Thermal Imaging Scopes
LD19A / HD19A / LD38S / XD50A

Each of the four available models of Pulsar's Quantum Thermal Imaging Scope easily penetrates fog and smoke to provide high resolution thermal images, day or night.

Differentiated by their thermal range, their thermal core refresh rates and whether they can be exported, if you're in the market for a reasonably priced hand held thermal imaging scope then you'll probably find a Quantum that will meet your needs. Here's the rundown on the four models you can choose from:

Pulsar Quantum LD19A Thermal Imaging Scope
515-yard range | 9Hz frame rate | exportable

The lowest cost member of Pulsar's Quantum family, the features packed into the LD19A make it the dominant thermal imaging scope at this price point.  Powered by a 9Hz thermal imaging sensor, the scope's 1x16, f1.2, germanium glass lens produces a high resolution thermal image out to a range of 515 yards.  Moreover, the Pulsar Quantum LD19A Thermal Imaging Scope can be exported.

The LD19A features a 2-power digital zoom, “white hot” and “black hot” heat signature settings and three operating modes (city, forest and identification) to enhance image contrast based on your surroundings.  The tripod mountable scope is also equipped with a 3.5 mm output jack that can be connected to an available digital recorder, accessory mounting rail and available external power supply.

The LD19A is typically used for commercial purposes such as detecting leaks, poor ventilation or hot spots in homes and buildings.

Pulsar Quantum HD19A Thermal Imaging Scope
515-yard range | 30Hz frame rate | not-exportable

Pulsar's Quantum HD19A ups the ante by adding a higher speed 30Hz thermal imaging sensor to the mix. The result is smoother image pans, an important consideration for surveillance applications that demands quick scans of large areas.

Features include 2-power digital zoom, “white hot” and “black hot” heat signature settings, three image contrast modes, video/power jacks, tripod mounts and a 1x16, f1.2, germanium glass lens set.

Affordably priced, the Pulsar Quantum HD19A's smooth, high-speed 30Hz thermal imaging sensor and ability to penetrate fog and smoke - day or night - make it an ideal surveillance tool for both search and rescue and law enforcement applications.

Pulsar Quantum LD38S Thermal Imaging Scope
1,039-yard range | 9Hz frame rate | exportable
This scope is yet another variation on the lower priced LD19A, though in this case the change is restricted to the addition of higher powered 2.1x32, f1.2, germanium glass lens.  This change to a higher powered lens set more than doubles the thermal imaging range to 1,039 yards.

This thermal scope's features remain the same; 2X digital zoom, “white hot” and “black hot” heat signature settings, three image contrast modes, video/power jacks, dual ¼-inch tripod mounts and the accessory rail mount. 

With a cumulative digital zoom magnification of 4.2X, the Pulsar Quantum LD38S Thermal Imaging Scope scores high marks for long-range thermal reconnaissance applications.  And of course thanks to its 9Hz thermal imaging sensor, this scope can be exported.

Pulsar Quantum XD50A Thermal Imaging Scope
1,200-yard range | 50Hz frame rate | not-exportable

Topping off Pulsar's Quantum Series, the XD50A Thermal Imaging Scope features a powerful 2.5x42, f1.2, germanium glass lens that extends this scope's thermal range to 1,200 yards.

Moreover, with the addition of an upgraded 50Hz thermal image sensor, long-range surveillance imaging is incredibly smooth no matter how quick the pan.  And like every scope in the Quantum series all the standard features remain, including “white hot” and “black hot” heat signature settings, three image contrast modes, video/power jacks, dual ¼-inch tripod mounts and an accessory rail mount.

Combined with the unit's cumulative digital zoom of 5-power, the Pulsar Quantum XD50A Thermal Imaging Scope represents one of the most powerful long-range, reconnaissance imagers in its class.
