Brimrose Technology is Awarded Two Phase I STTRs

Sparks, MD - Brimrose Technology Corporation (BTC) has received two new Phase I STTR (Small Business Technology Transfer) awards.

DARPA has awarded Brimrose Technology an award for $100,000 for a proposal entitled "Narrow Band Gap Quantum Dots and Quantum Wires for Mid-Wave Infrared Focal Plane Array Detectors."

The DARPA proposal's objective is "to demonstrate the feasibility of producing quantum dot focal plane arrays for mid wavelength Infrared (MWIR) photodetectors." The study may extend the detection range into the long-wavelength Infrared (LWIR). RTI is a collaborator on the project.

"These photodetectors will find many uses both in military and civilian applications such as night vision, surveillance, IR countermeasures and IR spectrometers," according to Dr. Dajie David Zhang, a senior scientist at BTC and the DARPA STTR project’s principal investigator.

BTC also has received a new Phase I STTR from the U.S. Missile Defense Agency (MDA) focused on "Light Weight Optics for High Power Directed Energy Applications."

The objective of the MDA award is to demonstrate the feasibility of producing light weight and thermally manageable integrated optical systems suitable for airborne and space high power directed energy applications.

"This project will focus on improving two of the most important parts of a high energy mirror design, the reflective mirror surface, and the multifunctional substrate," according to Zhang, also the principal investigator for this STTR.

Brimrose Technology is working in collaboration with Penn State University's Applied Research Lab on the MDA award.

Brimrose Introduces Optical Taggants to Again Let The U.S. Warfighter "OWN THE NIGHT"

Washington, D.C. - Brimrose Technology Corporation is introducing a new generation of optical taggants which will again let the U.S. warfighter own the night and day in terms of being able to see and process critical information beyond what the human eye can see even with the help of 3rd generation night vision goggles. Optical taggants are target identifiers located on friendly or enemy personnel or material that enable the Warfighter to make critical decisions in target identification in a tactical environment. The announcement is being made here at the AUSA conference.

Brimrose is supplying its highly advanced SWIR AOTF (Short Wave Infrared Acousto-Optic Tunable Filter) hyperspectral imager to provide the Warfighter with "special eyes" to find and locate TTL (Tagging, Tracking & Locating) taggants which are not observable by commonly used 3G night vision goggles, which are globally available.

"The 21st century battlefield is evolving rapidly and for the U.S. Army to stay out in front of it we need to continue to employ tools and tactics that keep us ahead of those who would do harm to our nation" says Brimrose CEO Dr. Ron Rosemeier. "With these new taggants, we are opening opportunities at the edge that will make our fighting forces more effective."

The SWIR AOTF hyperspectral imagers let the soldier in the field identify optical taggants at a highly specific wavelength which is outside of the commonly viewed IR frequencies. When the taggant activates or fluoresces, the soldier can track friendly troop and material movements.

The soldier also has a Brimrose covert source invisible to the naked eye that he can track and locate which provides critical information about enemy troop and vehicle movement, weaponry, contraband, as well as being useful for other purposes. This source is also beyond the range of 3G night goggles.

It is critical that the optical taggants only be seen by the observing party, the U.S. Warfighter. When all parties have goggles that can see the activated taggants, as is the case with 3G IR goggles, they lose their effectiveness. The new generation of Brimrose taggants can be seen only by those using SWIR technology.

"The U.S. soldier must be in the position where he can make informed decisions” says Dr. Rosemeier. “U.S.-only readable optical taggants allow him to do that on a variety of fronts, including at the edge, where the gathering of enemy intelligence is critical."

The optical taggants themselves are made of a proprietary fiber material. Brimrose performs materials research with nano-materials and quantum dots, both of which are used to make the next generation of optical taggants.

The Brimrose hyperspectral imager and optical taggants will be demonstrated at the Brimrose booth (#1638) at the AUSA show Oct 21-23.

Brimrose Introduces Flight Capability with Launch of HERO

Sparks, Md. - Brimrose, a photonics and high-technology company, is launching an exciting new capability as the company has unveiled a series of reconfigurable, multipurpose unmanned aerial vehicles (UAVs) for potential tactical, surveillance and emergency applications.

With the advent of HERO (Heli Engagement Reconnaissance Observatory), Brimrose has the potential to collect a wide variety of data from the air using sensing and other data-gathering equipment.


"A core mission of Brimrose has been to help our clients better identify and characterize the environment and elements around them through our advanced acousto-optic technology and other products," said President and CEO Dr. Ronald Rosemeier. "By introducing controlled flight, HERO provides us with an entirely new dimension to use this sensing and data-gathering equipment extremely effectively."


The HERO series—which already has undergone preliminary testing--includes a variety of power, weight and multi-blade options, and provides real-time, 360 degree view capability that includes both CCD Color Video and Infrared (IR) Night Vision. The series also offers auto return-to-home base and point-to-point GPS navigation. The drone offers up to 30 minutes of flight time and up to 13 pounds (5.9 kg) of custom payload.


Some potential applications include active and passive target monitoring, crop monitoring, search and rescue, crowd control/monitoring, flood/fire disaster monitoring, and environmental monitoring.


Brimrose is a world technology leader in the area of acousto-optic components, NIR instrumentation, and advanced materials for space applications serving the U.S. government and worldwide commercial industry since 1979. For additional information, send email to office@brimrose.com.

Brimrose Received Two New Phase I SBIR Awards from The U.S. CBD Unit.

Acousto-Optic Tunable Filter-based (AOTF) Polarimetric Imaging System for Stand-Off Chemical Detection

The first award (CBD 13-104) is for an Acousto-Optic Tunable Filter-based (AOTF) Polarimetric Imaging System for Stand-Off Chemical Detection. Brimrose will apply its considerable understanding of AOTFs in the long-wavelength infrared (LWIR) region. The company intends to optimize the device fabrication techniques using mercurous halide materials.

The goal for Phase I of the research is to develop and design an AOTF spectral polarimetric imaging system that uses an LWIR focal plane array as the detector. In Phase II, the system will be fully built and demonstrated. The variety of potential applications include remote sensing, pollution detection, environmental monitoring and mapping, automobile emission monitoring, and process control in the manufacture of foods, beverages, semiconductors, petrochemicals and pharmaceuticals.

Development of Low-Cost Infrared Focal Plane Array for Passive Chemical Detection Using Colloidal Quantum Dots (CQDs)

The second award (CBD 13-105) is for Development of Low-Cost Infrared Focal Plane Array for Passive Chemical Detection Using Colloidal Quantum Dots (CQDs). This research is being done in collaboration with Research Triangle Institute in North Carolina.

The goal is to develop low-cost, long-wavelength infrared focal plane arrays (LWIR FPAs) using colloidal quantum dots of II-VI semi-metallic compounds. Brimrose intends to develop reliable fabrication processes to make mercury telluride (HgTe) CQDs, and methods to extend the capabilities into the LWIR range will be examined. The work is exploratory in that it has mainly occurred in the mid-IR range heretofore.

This research has the potential to replace far more expensive sensors that only operate effectively at cryogenic temperatures. Also, the techniques used to fabricate existing FPAs are very expensive and have low yields of usable sensors. The Brimrose research may lead to far less expensive sensors operating at room temperatures that potentially could be helpful to first responders, fire fighters, and military post-blast reconnaissance teams.
