Luna Optics LN-QE-B50 Specifications

Quantum Elite Sensor and Night Vision Performance

The LN-QE-B50 uses Luna Optics' Quantum Elite UHD CMOS sensor, with a published light sensitivity of 0.0005 lux. This sensor is designed to capture more detail in low-light conditions, including situations where conventional optical binoculars provide a limited view. The 50mm f/0.9 objective lens is designed for high light transmission, helping the sensor gather available light during nighttime observation.

The binoculars offer several viewing modes, including full color for daytime use, nighttime color, black and white, green phosphor, white phosphor and amber. The appropriate mode depends on ambient light, the subject and the user's viewing preference. Luna Optics also specifies an Ultra Night Vision mode intended to improve nighttime viewing without always relying on infrared illumination.

6x Optical Magnification and 36x Digital Zoom

The LN-QE-B50 provides 6x optical magnification and digital magnification up to 36x. Its 50mm objective lens and 10-degree field of view at 6x provide the starting view, while digital zoom enlarges the image electronically. Digital magnification does not add optical detail in the same way that a higher-power optical system can, so the clearest viewing generally comes from using the lowest magnification that meets your needs.

Electronic image stabilization is available at the native 6x optical setting to help steady the viewed image and recorded footage. For more information about the practical differences between zoom types, see Digital Zoom vs. Optical Zoom in Night Vision.

Dual 850nm and 940nm Infrared Illuminators

The LN-QE-B50 includes two integrated infrared illuminators: 850nm and 940nm. The 850nm illuminator is generally the better choice when illumination distance is a priority. The 940nm illuminator produces less visible red glow and may be preferable when minimizing visible illumination is important, although effective range depends on conditions and the target.

With its sensitive sensor and integrated infrared illumination, Luna Optics advertises nighttime visibility of up to 1,000m. This is a manufacturer-stated maximum, not a guarantee of identifying details at that distance in every environment. Ambient light, weather, target size, contrast and the selected illuminator all affect practical performance.

Integrated 1,500m Laser Rangefinder

The built-in laser rangefinder measures distance to help you judge how far away a target or landmark is. Luna Optics specifies a maximum range of 1,500m (1,635 yards) and a 905nm Class 1 laser. Actual rangefinding performance varies with target size, reflectivity, weather and other environmental conditions.

The integrated rangefinder is particularly useful when you need distance information without carrying a separate rangefinding device. It complements the binoculars' observation and recording features, making the LN-QE-B50 a versatile tool for outdoor observation and other applications where knowing target distance is useful.

4K Video, 16.1MP Photos and Wi-Fi

The LN-QE-B50 records video in several formats, including manufacturer-rated 4K, and captures still images at 5360 x 3008 pixels (16.1MP). Recorded files can be saved to a microSD card with support for capacities up to 512GB. A 32GB microSD card is listed among the supplied accessories in Luna Optics' product information.

Built-in Wi-Fi supports connection to compatible iOS and Android devices for viewing and streaming. The micro-HDMI output provides 1080p video to a compatible external display. Electronic image stabilization helps steady recording when used at the supported 6x optical magnification.

Resolution note: Luna Optics markets this model as a 4K device, while its technical sheet lists the sensor resolution as 2880 x 2160 pixels and describes video modes as 4K, 2K, 1080p and 720p. These specifications are reproduced as stated by the manufacturer rather than assuming the sensor dimensions are the standard 3840 x 2160 UHD format.

18650 Battery Options and All-Weather Operation

The binoculars support two or four 3.7V 18650 batteries and can also operate from an external 5V/2A power bank connected through USB-C. Luna Optics specifies up to 8.5 hours of operation with the infrared illuminators turned off; actual runtime will depend on settings, battery capacity, wireless use and IR operation.

The operating temperature range is -22°F to 122°F, making the LN-QE-B50 suitable for use across a broad range of outdoor conditions. Its dual AMOLED displays are designed to operate in cold weather, and the binoculars include a micro-HDMI output, Wi-Fi connectivity and expandable microSD storage.

LN-QE-B50 vs. Other Luna Optics Night Vision Binoculars

The LN-QE-B50 is the Quantum Elite model, featuring the more sensitive 0.0005-lux sensor, f/0.9 objective lens and dual 850nm/940nm infrared illuminators. The LN-QD-B50 and LN-QD-B50-PRO are Quantum Digital alternatives with a different sensor platform and 850nm infrared illumination. The QD-B50-PRO also features a rangefinder rated to 1,500m.
