Hyperspectral Camera

VTT's (Espoo, Finland) hyperspectral imager continues to observe the earth on board the Aalto-1 nanosatellite. The hyperspectral camera on Aalto-1 operates in a wavelength range of 500–900 nanometres and is half a cubesat unit (0.5U) in size, or 5 cm × 10 cm × 10 cm. While the camera is up in space, it has been possible to program the operation wavelengths from Earth, making it easy to scale the same camera hardware to enable different applications. The small camera is extremely rugged, surviving a grade X solar storm while still continuing to supply high-quality data.

Machine Vision Cameras

Teledyne DALSA (Waterloo, Ontario, Canada) recently introduced its newest Genie Nano cameras with eight new monochrome and color models built around SONY® image sensors. These industry-first 5-Gigabit GigE Vision cameras feature resolutions from 3.2 Mpixels to 12 Mpixels with more models to follow, including a 5 Mpixel polarized model. These new Genie Nano models also feature the brand new 5GBASE-T link speed. Frame rates range from 190 to 63 fps.

IEEE 802.3bz-2016 is the expanded standard for Ethernet over twisted pair copper wire at speeds of 2.5 Gbit/s and 5 Gbit/s. This creates intermediate speeds between existing standards 1 Gigabit Ethernet and 10 Gigabit Ethernet. The resulting standards are named 2.5GBASE-T and 5GBASE-T. 5GBASE-T technology allows Ethernet links to offer greater flexibility with new data rates of up to 5 Gbps over commonly deployed Cat5e cabling. The technology boosts data throughput of up to 100 meters through twisted pair copper cabling.

GigE Vision Cameras

LUCID Vision Labs, Inc. (Richmond, BC, Canada) recently announced the addition of new 3.2 MP and 5 MP polarization models to its Triton™ GigE Vision camera series. The 3.2 MP Triton camera features the 1/1.8” Sony IMX265 global shutter CMOS sensor running at 38 fps. The 5 MP polarization Triton models feature the 2/3 Sony IMX250MZR monochrome and the IMX250MYR color global shutter CMOS sensors running at 24 fps. Featuring a pixel size of 3.45 μm, the polarization image sensors have four different directional polarizing filters (0°, 90°, 45°, and 135°).

Triton GigE Vision cameras feature Active Sensor Alignment for superior optical performance; a lightweight, compact 29 × 29 mm size, and IP67 protection. The M12 Ethernet and M8 I/O connectors provide a robust connection resistant to shock and vibration and are protected from dirt, dust, and water. By adding an optional IP67 sealed lens tube, the Triton can operate in harsh environments without the need for bulky enclosures.

Hazardous Location Camera

Larson Electronics LLC (Kemp, TX) announced the release of a new hazardous location camera designed for discreet monitoring and remote observation in indoor and outdoor industrial environments. The HAL-CMR-IP-POE-PTZ-20MP produces crisp 1080p full-HD high-resolution images day and night. This 2 MP explosion proof camera is capable of capturing images 1920 × 1080 resolutions and features pan, tilt and zoom controls. The day/night unit offers up to 3x zoom for far-flung targets. Operators can power the monitoring device via POE or wall outlet. Alternatively, a network cable can be used to power the unit, when connected to POE-enabled devices, such as a POE NVR or POE switch.

The HAL-CMR-IP-POE-PTZ-20MP is constructed of durable copper-free aluminum and has an unbreakable polycarbonate lens. Four NPT hubs allow operators to safely wire and securely mount the unit in vessels, tanks, reactors, walls, ceilings or pendant configurations. This explosion proof camera is NEMA 3 and 4 rated.

Fixed Focal Length Lenses

Edmund Optics® (EO) (Barrington, NJ) has introduced the TECHSPEC®HPi (High Performance Instrumentation) Series for instrumentation imaging applications and the TECHSPEC® HPr (High Performance Ruggedized) Series of stability ruggedized lenses.

The TECHSPEC® HPr Series Fixed Focal Length Lenses are high performance, ruggedized versions of the HP Series Lenses. Featuring up to 9 MegaPixel resolution, these lenses are stability ruggedized to maintain pointing stability, even after shock and vibration. All of the individual optics are glued into place to reduce pixel shift on the image. TECHSPEC® HPr Series Fixed Focal Length Lenses feature robust mechanical components with a simplified focus and a stainless steel locking C-Mount clamp.

Utilizing the same design and internal optics as the HP Series, the HPi Series Fixed Focal Length Lenses are designed for instrumentation imaging applications. These industrial ruggedized lenses offer a wide variety of fixed aperture options, with up to 9 MegaPixel resolution across the field. Using the same adjustable, lockable focus iris as the HP series lenses, the user may set and lock the best focus position for instrumentation integration.

Laser Diode Driver

The ALPhANOV (Talence, France) laser diode driver range allows the users to get the best performance from their device while ensuring that it is protected at all times. The new product, called “Shaper,” completes this range by adding very high precision temporal pulse shaping capabilities between 500 ps and 2 μs with a repetition rate of up to 250 MHz, a temporal resolution of 500 ps and an intensity dynamic of 48 dB up to 2A.

The Shaper board includes a multifunctional synchronization unit with AWG (Arbitrary Waveform Generator), 3 built-in delay generators for synchronizing external instruments or other external laser amplifiers, and a TEC controller to regulate the temperature of the laser diode.

The driver is available in two versions: the “external modulation” version drives the laser diode with square waveforms and generates a shaping signal that is compatible with external devices such as acousto-optic or electro-optic modulators. The “direct modulation” version allows the pulse shape to be applied directly to the laser diode and a new functionality allows the user to remove spurious effects such as “gain switch” relaxation peaks.

SWIR Detectors

Sofradir-EC (Fairfield, NJ) has announced the availability of two new SWIR InGaAs sensors. The 640 × 512 VGA format detectors with 15-micron pixels are available in two versions: the SNAKE SW, a hermetically sealed metal package that includes an integral TEC (thermo-electric cooler), or the SNAKE SW TECless, a hermetically sealed ceramic package without a TE Cooler. Both detectors are designed for wavelengths ranging from 0.9 μm to 1.7 μm and boast low noise, fast frame rates up to 300Hz, excellent image quality and a pixel operability of >99.5%.

The Tecless version can be configured with or without an anti-reflective coated window providing the end user additional system architecture flexibility. Applicable for use in low earth orbit (LEO) systems, the SWIR detectors are compact, utilize very little power and are cost effective. In particular, the SNAKE SW Tecless has a footprint of only 0.65” × 0.65” and consumes <160 mW in output mode.

Fiber Optics Transmitter & Receiver

Link Electronics (Jackson, MO) introduced the PFO-100-T&R, a compact 3G/HD/SD-SDI or ASI fiber optics transmission system. This unit operates with single mode fiber optics cable or, multi-mode fiber optics cable. The module is SDI pathological test compliant, and features a built-in equalizer, cable driver, and reclocker. The combined PFO-100T (transmitter) and PFO-100R (receiver) are a matched pair for specific wavelengths, either the standard 1310 nm or any requested wavelength between 1270-1610 nm. At only 4 oz., it is capable of transmitting up to 24 miles (40 km); 48 miles (80 km) available on request.

The PFO-100-T&R supports SMPTE ST 424 (3G-SDI 3Gb/s), SMPTE ST 292 (HD-SDI 1.5Gb/s), SMPTE ST 259 (SD-SDI 143/270/360 Mb/s), or SMPTE ST 310 (DVB-ASI). The modules include LED indicators to display Power ON and SDI signal presence from BNC (transmitter) or from fiber optic (receiver), providing critical system diagnostic information at a glance. The 3G/HD/SD-SDI or ASI fiber optical transmission system uses its own power supply or any 5 volt DC supply, with a standard latching power jack DC input.
