MCD
High performance multi-channel infrared detector
Key Features: Four discrete high sensitivity optical channels in one package Allow simultaneous measurement of multiple gases/materials
Suitable for NIR and MWIR sensing across 1-5.5 microns Compact, multi –element TO-5 package Ideal for portable instruments where size is critical Hermetically sealed for use in harsh environments
Standard MCD-15 configuration available with optical filters Filters target CO2, CO and various hydrocarbon measurements
Designed for long term reliability in the field
New application demands are driving instrument manufacturers to measure more materials or gases in smaller devices while still maintaining high sensitivity and quality. To meet these challenges, the MCD (multi-channel detector) product family provides four discrete optical channels in a compact TO-5 package. Offering Cal Sensors’ renowned long-life, high-sensitivity PbS or PbSe detectors, MCD products cover from 1 micron up to 5.5 microns wavelengths for near- and mid-infrared applications. These multi-channel detectors are designed in a quadrant configuration. The standard MCD 15 solution provides four isolated optical bandpass filters mounted on four discrete elements. Well suited for a variety of applications, including air quality monitoring and emissions analysis, the filters have peak wavelengths of 3.34, 4.26 and 4.60 microns to cover hydrocarbon (such as methane), CO2 and CO test requirements. For over 25 years, Cal Sensors has been manufacturing and selling high performance PbS and PbSe infrared detectors.
Having established a reputation for highly controlled manufacturing processes, customers can rely on consistent, repeatable performance and superior customer service. Supporting all stages of development, from early prototyping to high volume production, Cal Sensors is dedicated to helping customers develop market-leading instruments. Custom requirements can be addressed by contacting the Cal Sensors’ sales team. Applications: Medical gas analysis Industrial gas analysis Auto and aviation emissions monitoring Air quality monitoring or analysis Environmental In tunnels Underground

PIRE PLUS
High-speed infrared emitter with integrated drive electronics
Key Features: Fast pulse rates, up to 180 Hz with 50% modulation depth
Adjustable pulse rates with 0 to 5V control circuitry
High output emitter, .04 watts/cm2 at one inch from filament
Compact, reduced footprint solution
Software support of custom pulse configurations
Broadband output with 88% emissivity
Lower overall system costs
Typ. MTTF of >26,000 hrs at max rated power
The high-performance PIRE
PLUS, combines a
high-speed pulsable emitter with its correspond-ing drive electronics on a compact 14 pin circuit board. Designed to maximize output over a 1 Hz to 200 Hz range of pulse speeds, these complementary assemblies enhance signal to noise performance, while minimizing the overall system footprint. The construction and implementation of the emitter and control circuitry, optimize performance by matching the drive waveform for the desired operating frequency. This ensures peak output temperatures at all pulse frequencies and promotes the highest output for any application. With typical pulse speeds of 180 Hz and 50% modulation depth, even trace elements in low parts per million concentrations can be accurately detected. The PIRE
PLUS sub-system is an ideal solution for
a variety of applications. The control circuitry will exploit the capabilities of the high-speed source in any application, pulsed or steady state. With this emitter, controller set, designers can now focus on maximizing the overall system performance rather than interfacing with the source.
Applications: Gas analysis, medical and industrial Environmental monitoring Spectroscopy Process control systems Plastics sorting

IDA
Compact integrated infrared detector assembly
Key Features: • High sensitivity detector with integrated electronics including:
� Single stage TEC and thermistor for temperature control � Hermetic sealing for use in harsh environments � A choice of configurations � A compact TO-8 package
• Eliminates need for external interface boards
• Ideal for portable instruments where small size is critical
• Less susceptible to noise than external circuitry configurations
Standing out from other single-element detectors, IDA was designed to minimize size and simplify system implementation, without sacrificing performance. It promotes multiple arrangements, offering a choice of 1x1 mm or 2x2 mm detection schemes, PbS or PbSe materials and supporting single or bipolar bias supplies. In addition, designers can specify whether they want to configure it with a unity gain DC buffer or AC coupled 10 dB gain amplifier. The compact size significantly reduces the footprint as compared to traditional detector schemes and provides a hermetically sealed assembly for harsh environments. IDA is ideal for manufacturers of portable equipment where size, durability and costs are so important. The IDA design takes advantage of the shielded, high impedance detector node to minimize noise. With the integrated thermistor and thermoelectric cooler (TEC), IDA can manage temperature fluctuations reliably. These complementary features combine to optimize signal to noise ratio. Thus IDA is prepared to meet the challenges of today’s and tomorrow’s demanding applications.
Applications: � Gas analysis, medical and industrial � Emissions monitoring � Spectroscopy � Process control systems � Thermal imaging � Flame detection
