Obis CellX series


CP Series of thermoelectric modules and assemblies


Laird has released thermoelectric modules (TEMs) and thermoelectric assemblies (TEAs) that keep laser optics stable and at peak operating performance by controlling the operating temperature of medical lasers to within defined parameters. The thermoelectric modules and assemblies provide reliable solid-state operation with no vibration to ensure long life operation with low maintenance requirements, resulting in lower total cost of ownership in medical laser applications. TEMs offer precise temperature control


accuracy achieving ±0.01°C under steady- state conditions. They can cool to -100°C (6-stage) and pump up to 15W per square centimetre of heat, with higher heat pumping capacities achieved by wiring TEMs into an array. Commonly used in medical laser applications, the Laird CP Series can pump between 3 and 120W of heat. Available in numerous heat pumping capacities, geometric shapes, and input power ranges, the CP Series modules are designed for higher current and larger heat pumping applications with a maximum operating temperature of 80°C. Fitting into tight geometric space constraints, TEMs can be mounted in any orientation that cannot accommodate a much larger compressor- based system. www.lairdtech.com


Coherent has released a new family of flexible laser light engines, the Obis CellX series, which delivers up to four separate laser wavelengths from a single module, thereby lowering the complexity and overall cost of laser integration in multi-wavelength life sciences instruments, such as flow cytometers. Obis CellX is a compact one-box source in


which the lasers, electronic control and beam conditioning optics are all completely integrated in a single package. The CellX features a single controller board, common power and RS232/ USB connections, and a single I/O connector. Flexibility and utility are further enhanced by


NXIR-5C photodiode


Opto Diode has introduced the NXIR-5C, a red to near-infrared enhanced photodiode with a circular active area of 5mm2


. With a


spectral response from 320 to 1,100nm, this rugged photodiode is housed in a custom 4.7 x 4.9mm ceramic carrier surface-mount device (SMD) package. The NXIR-5C provides superior


responsivity with low reverse bias and high sensitivity at 0.62A/W for 850nm and 0.35A/W for 1,064nm. It offers a low dark current of 1nA, low capacitance of 5pF at 10V, and shunt resistance greater than 100MΩ. The NIR-enhanced detector is specially designed for laser monitoring, medical diagnostic equipment, industrial automation, scientific measurement, and military


LENSES AND OPTICS Glass manufacturing capabilities


LightPath Technologies has added glass manufacturing capabilities as part of its vertical integration strategy. As40Se60 chalcogenide glass or BD6 is being produced in high volumes in its Orlando, Florida, facility and can be used in many infrared applications. This also supports the precision diamond turned and coating options available through its subsidiary, ISP Optics. www.lightpath.com


42 Electro Optics May 2017 Flexpoint Mini laser diode module


Laser Components has introduced a 520nm Flexpoint Mini laser diode module. Its optical power can be set to any value between 0.4- 5mW, and depending on the chosen optical power, the laser safety level will be either class 1, 2, or 3R. The module’s small housing features dimensions of 8 x 40mm. The 520nm modules require 4.5-6VDC to


operate and can be built with the company’s optional integrated digital modulation circuit, allowing the laser to be turned on and off in quick succession. www.lasercomponents.com/uk

applications which require a wide operating temperature range from -40 to +125°C. The robust package features an AR-coated window that provides greater than 98 per cent transmission. www.optodiode.com


providing independent customer adjustment of the pointing and focus of each wavelength, allowing the TEM00 outputs to be aligned and positioned as needed for each specific instrument.


CellX is based on Coherent’s Obis plug-


and-play smart platform. It is available in two standard formats – a three-channel version with outputs at 405, 488 and 640nm, and as a four- channel engine that also includes 561nm. Beam parameters are well-suited to flow cytometry and CellX offers a choice of either 50mW or 100mW output power per wavelength, suiting cell analysis. www.coherent.com
