Trilinear Line Scan Cameras

Teledyne e2v (Milpitas, CA) has announced its next generation of line scan cameras — the high-resolution ELiiXA+ trilinear color range. These new 8k pixel cameras are suited for industrial applications such as print, label, textile, electronics, and PCB inspection, that require high color resolution and image sharpness.

The trilinear configuration of the new camera not only enables color images, but also makes it possible to use a multi-light setup to discriminate the light coming from different angles in a single scan. This reduces production time, compared to using sequentially pulsing lights.

The first camera model in the ELiiXA+ trilinear color range has a CameraLink interface and can be operated at up to 33 KHz with an 8k pixel resolution. An entry-level product, it can replace CCD trilinear cameras, enabling system integrators to increase speed or resolution.

Color Measurement System

FluxData (Rochester, NY) has released the SpectraNova™ D8-M2 color measurement system, designed for reliability and efficiency. The measurement head is sealed, with a sapphire window to protect the integrating sphere from a factory environment, and is easily cleanable in the field. Measurements are reported instantly to software through a machine-to-machine interface, eliminating the need for a human operator.

Designed for industrial applications, it is non-contact, rapid, compact, and correlates with QC laboratory systems. It also includes 8° diffuse geometry, offers reflectance and CIE colorimetric data output, rapid measurement cycles of less than 150 milliseconds, and requires minimal maintenance. With a head weighing 0.36 kg (0.80 lbs.) and the system weighing 2.29 kg (5.05 lbs.), the system has the potential to be placed virtually anywhere on a production line, with the supporting electronics housed in a separate enclosure.

VIS-SWIR InGaAs Camera

Raptor Photonics (Larne, Northern Ireland) has launched an additional member to its family of Visible SWIR cameras with the Ninox 1280, offering HD resolution for high-end scientific and astronomy applications. Using a 1280 × 1024 InGaAs sensor from SCD, cooled to -15°C, the Ninox 1280 offers visible extension from 0.4 μm to 1.7 μm to enable high sensitivity imaging. It will offer less than 40 electrons readout noise combined with a low dark current reading. The camera will offer an intrascene dynamic range of 69 dB enabling simultaneous capture of bright & dark portions of a scene.

Available with a 12-bit CameraLink output, the Ninox 1280 will run up to 60 Hz. The camera will feature on-board Automated Gain Control (AGC), which will enable the best contrast image from low light to bright, as well as an on-board intelligent 3 point Non-Uniform Correction (NUC) algorithm. The Ninox 1280 is cooled to -15°C, and offers both TEC and water-cooling options, significantly reducing dark current and enabling longer exposures.

Precision Alignment Lasers

Laser Components (Bedford, NH) is offering two additions to its portfolio of high-precision alignment lasers: LT-PLM-635-01-C1 and LT-PLM-IRB-635-01-C1. At the exit point, the beams of these modules have diameters of 1 mm and a squint angle of 0.05 mrad, which equals 5/100 mm per meter distance from the target. The small exit diameter produces an exceptionally small dot on the target area. Due to its higher divergence, its use is recommended at distances of up to 3m. Both profiles are available in a 24 mm housing with M12 connections or as a mobile version with an integrated battery in a 35 mm housing.

The “squint angle” defines the aberration of the laser beam from the central axis of the housing. This effect can be watched by putting the laser module on a plane surface and rotating it along its longitudinal axis. The laser spot will then move in a circle on the wall.

SWIR Video Core

Semi Conductor Devices (SCD) (Haifa, Israel) has released a new SWIR Imager (SWIRi) Video Core.

The SWIRi is a low SWaP, 15μm, high sensitivity InGaAs SWIR (Short Wave InfraRed) Video Core Imager that has been specially designed to be a Low Light Level Sensor in man-portable and handheld devices. It comes with SCD’s new low SWaP-C detector package and an SCD SNIR ROIC.

The new core works in conjunction with dedicated algorithms to meet the requirements of low light night vision, leveraging the “Night Glow” phenomena to provide high performance, even in conditions of moonless nights and adverse weather.

Thin-Film Filter Photodetectors

Opto Diode Corporation (Camarillo, CA) is introducing the SXUV100TF135 and SXUV100TF135B photodiodes with integrated thin-film filters. The detectors each feature a 100 mm2 active area and a directly-deposited thin-film filter for detection between 12 nm and 18 nm. Both have typical responsivity of 0.09 A/W at 13.5 nm and are optimized for different electrical performance. Operating and storage temperatures range from -10°C to +40°C in ambient environments and from -20°C to +80°C in nitrogen or vacuum environments.

The SXUV100TF135 is optimized for higher speed reverse bias voltage operation. The device has low capacitance, typically 260 pF, with a reverse bias voltage of 12 volts. The SXUV100TF135B is optimized for zero bias voltage operation where low dark current is of paramount importance. The detector has a high shunt resistance greater than 10 MΩ.

White Light Source

The Mighty Light Plus (ML+) from Spectrolight (Irvine, CA) is a high power white light source for microscopy, white light inter-ferometry, machine vision, and precision inspection applications, that delivers up to 7 watts from a 10 mm diameter, detachable, armored light guide. It provides high spatial uniformity, suitable for both wide-field and focused spot illumination applications. The air-cooled package (including a low noise power supply) is only 340 mm × 160 mm × 140 mm.

An available optional collimator enables the light guide output to be directed into a variety of free space optics applications or instruments and can interface directly with Spectrolight Flexible Wavelength Selectors. This provides a low-cost, smoothly tunable, narrowband light source that can be tuned to match the excitation spectrum of a wide range of fluorophores. The 3400K bulb temperature delivers outputs as short as 350 nm, while producing useful power above 2.5 μm. Rotation of a single knob enables the output power to be smoothly varied from 0 – 100%.

Optical Transceivers

Bowman (Schaumburg, IL), has introduced its P Series, benchtop XRF coating measurement instrument. It simultaneously identifies elements Al13 through U92 on the periodic table in each of up to 5 coating layers, with high precision and speed. Standard system configurations include a four-position collimator assembly, variable focus camera for applications with recessed areas, extended-life micro-focus X-ray tube, and solid-state PIN detector. The detector has well-defined element peaks, eliminating the need for secondary filters. Minimal peak position drift assures high stability over time and extends the interval between recalibrations.

The intimate proximity of the X-ray tube and detector produces more than three times the photon counts of conventional XRF equipment, and in a shorter measurement time. The extended programmable X-Y axis, suits it for measuring small features, or parts such as fasteners, connectors, and PCBs. Table size is 25” × 25”; travel is 10” × 10”.
