Sensors & EW defence companies in Lithuania

Designs and manufactures electro-optical and laser systems for soldiers, border surveillance and airborne or naval platforms, drawing on in-house semiconductor expertise developed since 2011.

Laser Aiming and Illumination Systems

A family of laser devices for targeting, marking, illumination and designation across visible to extended SWIR wavelengths. Named models include the LP5X (handheld or weapon-mounted pointer for close to medium distances), the FTAL LS-850e (optimised for extra-long distances) and SM and LM series illuminators covering ranges from meters to tens of kilometres. All devices are designed for dismounted soldier use.

Thermal Sights and Surveillance Cameras

Uncooled long-wave infrared (LWIR) devices for sighting and observation. The HTR-5G is a standalone machine-gun sight supporting calibres up to .50 cal. The HTR-5U is a clip-on unity-magnification sight aimed at sharpshooters and snipers, with options for multiple power sources and video recording. The DATS3 is an ultra-compact sight that can be used standalone, as a clip-on or helmet-mounted. The LW15-100S is a stationary surveillance camera with continuous zoom for perimeter and border applications.

SWIR Weapon Sights and Cameras

Short-wave infrared systems that provide passive night vision and the ability to see through obscurants such as dust and smoke. The SWIR S100U is a weapon sight for medium to long distances, operating simultaneously across visible, near-infrared and SWIR bands with autofocus, video recording, laser pulse detection and an integrated 1550 nm illumination laser. A SWIR surveillance camera variant is also offered for observation roles.

Night Vision Devices

Image-intensifier-based night vision devices combining advanced tube technology with Brolis's own out-of-band NIR illuminators for covert operations. The Twins and BPS14 are the primary named devices in this category, suited for dismounted soldier applications.
