The operation of a diode laser in spectroscopic applications requires highly stable control of the laser's driver current. The current control DCC 110 meets this requirement. The design permits usage with both anode-grounded and cathode-grounded laser diodes. A BNC modulation input connector allows for external modulation of the laser current or output power. An additional BNC connector provides a signal for monitoring the internal photo diode current of a laser diode. Two versions of the DCC 110 are available, with output currents up to 500 mA, or up to 3 A for high-power diodes.
Specifications
- output current range 0... 500 mA (DCC 110/500 mA)
or 0... 3 A (DCC 110/3)
- coarse switch for range selection of output current in steps of 50 mA
- fine tuning of output current or optical power by precision trimmers
- stabilization of constant output current and output power
- operation of laser diodes / photo diodes in any combination of polarity
- calibration of the photo diode current IPD for optical power monitoring
- external modulation of output current up to 10 kHz
- low noise: < 3 µA (DC to 1 MHz, 500 mA version) and < 10 µA (3 A version)
- width: 12 HP (60 mm)
- control module optimized for operation of the grating stabilized diode laser DL100

PCB Automotive Sensors Debuts High Temperature Preamplifier
Operating to +120 °C for NVH Powertrain & Vehicle Underhood Testing
The Automotive Sensors division of PCB Piezotronics (PCB®) has announced release of a new high-temperature preamplifier, designed to overcome high temperature testing challenges associated with NVH powertrain and vehicle underhood testing applications, and to broaden options for NVH test engineers collecting acoustic data in high temperature areas.
Automotive engineers routinely perform NVH tests in areas around the powertrain, where elevated operating temperatures can present major measurement challenges. Underhood temperatures can peak at +125 0C under normal driving conditions, and can be significantly higher near turbochargers and exhaust system components, such as manifolds and diesel particulate filters. In the past, test engineers were limited by preamplifiers offering temperature ranges to + 70 °C. Model HT426E01 is a 1/2" preamplifier operating from ICP sensor power, terminating with BNC connector and utilizing standard coaxial cables. The model features a low attenuation factor (-0.06 dB) and low noise characteristics, 4.9 µV, based on an A-weight scale.
Common applications include underhood measurements for benchmarking and issue identification, including engine radiated, induction, ancillary and turbocharger noise; near-field measurements on manifolds; mufflers; exhaust after treatment components; and tailpipe noise. NVH groups within OEMs and Tier 1 suppliers involved with testing of powertrain components will benefit most from this product.

Product Overview :
The Optopatch patch clamp amplifier from Cairn Research is a general purpose amplifier, incorporating a number of unique features in order to optimise its performance across a wide range of applications. The amplifier is designed for patch clamp recording, with the unique addition of a lock-in amplifier to enable measurement of membrane capacitance and resistance. This built in device has a unique "track-in" mode that keeps the lock-in amplifier in perfect balance, maintaining discrimination between resistance and capacitance and providing linear calibrated resistance and capacitance outputs. The Optopatch includes several other unique features, including our patented optical technique for measuring small currents over a wide bandwidth (up to 200 KHz), and circuitry for protection against overcompensation of series resistance and electrode capacitance, safeguarding your cells during a recording.
Applications :
Single channel recording
Whole cell recording
High resolution capacitance measurement
