Optical Products
Free Space Optical Modem
The qBeam Free Space Optical (FSO) Communications (FSOC) modem supports terrestrial and space-ground optical communications at GigE and 2.5 GigE speeds when coupled with a compatible optical telescope. The FSOC modem includes sophisticated forward error correction (FEC) and fade tolerant mitigation techniques to greatly reduce the effects of atmospheric scintillation on link performance and support longer range links than otherwise possible. Client interface is via a standard RJ45 connection (GigE) or SFP+ connection (2.5 GigE).
The qBeam FSOC modem is comprised of two assemblies, one housing the FPGA modem electronics and a second the receiver Avalanche Photo Diode (APD) detector. The APD module includes a safety shutter to prevent unsafe exposure of the APD sensor.

Multi-spectral SWIR Camera
qbeam’s high resolution, ultra-sensitive, configurable SWIR multi-spectral camera opens up new opportunities in the scientific, medical, security and industrial inspection fields. A unique dichroic prism architecture enables low optical insertion loss in each channel, while maintaining the original high resolution from each internal sensor. The camera's design supports a variety of UDT Sensor’s Unlimited sensors, providing unique imaging and sensing capabilities in the SWIR band.
For example, this multi-spectral camera can be used to provide a "color" capability in the SWIR band, with a wide range of tactical and imaging applications.

Laser Light Modulator
The Laser Light Modulator is a device that detects the presence of coherent or spectrally very narrow light and imparts a slow amplitude modulation on its intensity. Through the use of polarizers and a birefringent crystal, light with very narrow spectral content is modulated while broader spectral light (including sunlight) is not modulated. Therefore, this device can detect the presence of spectrally narrow light (including laser light) in the presence of higher intensity background light. Indirect or scattered light can also be detected.
This device is typically integrated onto a commercial camera lens and its use results in any pixels on the imaging plane that receive narrow spectral light to appear as blinking.

Laser Etching
qBeam’s high resolution, fast and configurable micro etching assembly allows new marking opportunities in the scientific, medical, asset tracking, security and industrial fields. The small size and low weight of the device allows in office or in field marking of many different material surfaces, from metals to plastics. Depending on character size, the etching assembly can write at speeds over 100 characters per second, allowing for the rapid marking of components. This assembly can reduce the burden of tagging or marking components for inventory or other purposes. The unit includes an embedded small form-factor PC, which reduces desktop space and allows for additional unit customization.

Optical Range Simulator
The Range Simulator is a multipurpose optical test-bed designed to allow simultaneous operation of both sides of a Free-Space Optical (FSO) link in the lab for testing and characterization. It consists of a pair of light-weight test platforms each configured with a large parabolic mirror and Single-mode or Multi-mode fiber precisely located at the mirror’s focus. The transmitter under test, aligned to the range simulator, outputs its beam toward the mirror. The focused beam undergoes a fourier transform placing the far-field intensity profile at the fiber tip. The light coupled into the fiber exits the other end of the fiber, diverging toward the second parabolic mirror, which produces a collimated beam that illuminates the FSO receiver. The power in the fiber can be modulated to simulate real world conditions. FSO links often require a minimum separation (sometimes greater than one kilometer) between transmit and receive heads due to multiple transmit or receive apertures or due to telescopes with obscurations. The range simulator solves this minimum range limitation.

Boresight Alignment Tool
The Boresight Alignment Tool is an optical benchtop or self-standing tool used to precisely co-align instruments with multiple free-space optical inputs or outputs. It consists of a large parabolic mirror and an optical fiber mounted at the mirror’s focal point.
A single-mode or multi-mode fiber is used to generate either a Gaussian beam or a beam with spatial intensity fluctuations (simulating optical turbulence). In addition, a large precisely collimated optical beam can be easily created for general lab use including interferometric applications.
