4x32 BROWE Combat Optic
 

The 4x32 BROWE Combat Optic (BCO) is a state-of-the-art optic that delivers highest quality optical glass, high precision machining, with a rugged military design. 

  

The BCO is a purpose designed and built optic ideally suited for tactical scenarios and well suited for military, police and sportsmen.  Its titanium housing is compact and light weight, yet nearly three times stronger than its aluminum counterparts, enhancing its ability to survive the rigors of field abuse under the most severe environmental conditions.

 

The BCO’s list of evolutionary technology is long and includes such features as:

 

 Target Light Sensor Technology  

The BCO has a cadmium-sulfide photocell located in the optical path providing great sensitivity and accuracy of the target light that is being transmitted through the optic, not ambient lighting. In tactical environments lighting levels are very liquid and constantly changing. When nanoseconds count there is no time to make manual illumination adjustments or search for a poorly illuminated reticle.  The Target Light Sensor Technology simplifies the operation and allows the operator to focus on the job at hand. 

 

 Single Intuitive Control (SIC)  

Gives the operator a simple button designed to control the illumination systems and simulate muscle memory.  With a single press of the SIC button the BCO will enter Automatic Mode; this will utilize the Target Light Sensor Teechnology by measuring the light transmission and automatically set the reticle illumination to the proper brightness.  The second press of the SIC button the BCO enters into Manual Mode.  This gives the operator complete control of the reticle illuination with the choice of 10 day settings and 3 night vision settings.

 

 BCO Utility Port  

The BCO utility port is a sealed port on the backside of the battery housing.  This port can be used to update the operating firmware or customize the existing program.  It can also be used to plug in a remote pressure pad switch, so the SIC button controls can be placed at a secondary location on the weapon.  This port can also be used to import or export power.  This means that accessories such as lasers or mini red dots could be powered from the BCO battery.  Alternatively, the BCO utility port is capable of importing power, to run on an external power source such as a central power system.

 

 Vibration Motion Sensor  

Designed to conserve battery life by placing the BCO in SLEEP mode if motion is not detected after two hours. The BCO has an average battery usage life of over 2000 hours with a minimum of 775 hours on max brightness.  In sleep mode the battey current is less than 1uA, which will give the BCO a shelf life of over 10 years.

 

Optical Design  

The BCO optical design is based on an internally adjustable roof prism optical system with an etched glass reticle.  This design was incorporated to maintain a short overall length, a platform that has proven itself successful with currently deployed products.  All lenses are precision ground of the finest quality optical glass available and are broad band anti-reflective coated possessing excellent light gathering capabilities even under low light conditions.  The glass etched reticle incorporates an LED coupled with microprocessor technology and a cadmium-sufide photocell to measure target light levels, automatically adjusting the reticle to match target lighting conditions.

4x32 BCO with Crosshair Reticle designed for 5.56mm, throw lever mount, Lenspen® cleaning tool, Surefire® Lithium 3v battery, storage case, and Operator Manual.

 


 

The 4x32 BROWE® Combat Optic (BCO) is a state-of-the-art optic that delivers the best-in-practice features of high-quality optical glass, high precision machining, and rugged military design with unique, next-in-practice features that puts the BROWE® Combat Optic (BCO) at the forefront of its class. The BCO offers customers a modern designed, internally-adjustable, combat optic with many unique features, such as Single Intuitive Control (SIC), Target Light Sensor Technology, field-programmable BCO Microcontroller, and a vibration sensor – all packaged in a rugged and versatile titanium housing.

Target Light Sensor Technology

 

 

 

Through extensive R&D, we’ve discovered that mounting a sensor in the light path behind the objective lens magnifies the incoming light and provides greater accuracy of the target light levels.  In AUTOMATIC mode, this key feature allows the BCO reticle to be properly illuminated even when the user and target are in dissimilar light and avoids sensor errors caused from ambient light.  More importantly, as an operator is on the move, the BCO will continuously adjust automatically. For example, light levels can vary extremely from streets to dark alleys and buildings. In today’s urban warfare, when a nanosecond can make a difference, there’s no time to search for a poorly illuminated reticle or make manual illumination adjustments. 

 

Single Intuitive Control (SIC)

 

 

The operation is simple and intuitive.  The idea is revolutionary.  The system rests in the OFF position or SLEEP mode.  The first press of the SIC button puts the system into AUTOMATIC mode. In this mode, the LED automatically adjusts to the ambient light conditions using the Target Light Sensor Technology.  The second press of the button puts the system in MANUAL mode.  It starts at the brightest day setting and cycles through ten (10) day and three (3) night vision settings with every press of the SIC button.  Holding the SIC button for more than three (3) seconds puts the system back to SLEEP mode, conserving battery life. Hitting the button again puts it back into AUTOMATIC mode. Simple. Intuitive. Effective.

BCO Microcontroller

 

 

The BCO Microcontroller is the brain of the operating system. Its custom program reliably and easily controls all of the electronic features. Unique to the industry, the BCO microcontroller is capable of being re-flashed with alternative programs via a sealed flash port on the back of the battery housing. This port can also be used to attach accessories such as a momentary remote tape switch.    

 

 

Vibration Motion Sensor

 

 

The vibration motion sensor conserves precious battery life by putting the electronics in SLEEP mode if motion is not detected after two hours. Additionally, if the SIC button is accidentally depressed in a carrying case or storage rack, the system automatically turns off after three (3) seconds. The BCO has an average battery usage life of 2000hrs. with a minimum of 775hrs. on max brightness.  In SLEEP mode, the battery will maintain the full 10 year life expectancy of a Surefire Lithium 123A battery.

 

 

Housing Designed to Accept Accessories

 

 

 

Versatility is at the forefront of the BCO housing design.  So you’ll find multiple areas for mounting “add-on” accessories. For starters, the OD of the eye-housing is a machined 30mm diameter surface with a 2mm groove for locking on dust covers or an assortment of other accessories.  Plus, two mounting bosses are placed on top of the housing for attaching additional accessories. On the objective end, we added a 42mm x 3mm OD groove and threaded the ID for added versatility for accessories, such as anti-reflection devices, dust covers, and/or laser filters. 

 


BCO Utility Port  

The BCO utility port is a sealed port on the backside of the battery housing.  This port can be used to update the operating firmware or customize the existing program.  It can also be used to plug in a remote pressure pad switch, so the SIC button controls can be placed at a secondary location on the weapon.  This port can also be used to import or export power.  This means that accessories such as lasers or mini red dots could be powered from the BCO battery.  Alternatively, the BCO utility port is capable of importing power, to run on an external power source such as a central power system.
