Receiver Modules
Detector Components + Pre-Amplifier Electronics
|
EOS specializes in integrating our broad product line of detector components with preamplifier electronics, creating receiver modules to accommodate almost any IR measurement requirement, from laboratory experimentation to industrial OEM applications.
The compact TO-packaged units offer the user the convenience and performance advantages of having the photodetector and amplifier in as close proximity as possible, minimizing EMI and microphonics. The versatile H-series units offer the user a group of interchangeable detectors, which provide optimal coverage of the UV-VIS-NIR, -MWIR, -LWIR wavelength regions. The cryogenic detector/amplifiers offer the ultimate in sensitivity for any given wavelength range as well as maximum immunity to EMI, microphonics, and accidental mishandling. These products insure the proper matching of the photodetector and amplifier characteristics for maximum performance. All the receiver modules work well with our Support Electronics.

|
TO-Style Receivers
|
The compact TO-packaged units offer the user the convenience and performance advantages of having the photodetector and amplifier in as close proximity as possible, minimizing EMI and microphonics. Hybrid photodiode/amplifier modules are available using any of our room temperature or TE-cooled photodiodes. A 4-pin TO-5 is used for fixed-gain, un-cooled units with active areas up to 3mm diameter. TO-8 packages are used for larger area devices and for applications where user selectability in terms of gain, bandwidth, and offset is desirable. TE-coolers for temperature stabilization and/or performance enhancement can also be added in the TO-8 packages and in the larger T-5 OFHC copper housings. Photoconductor/amplifier modules are available containing PbS, PbSe and HgCdTe devices. These use TO-8 or T-5 packages for either room temperature or TE-cooled operation.
The units are AC-coupled and can be provided with user selectable bias, gain, and bandwidth. Click here for part numbers |
H-Series Receivers
|
Modules containing any of the EOS photodetector components are available in the versatile H-series housing with either current mode transimpedence amplifiers or low-noise voltage amplifiers. From the users' standpoint, the modules are interchangeable; when coupled with the proper electronic, optical, and mechanical accessories, they provide a complete IR measurement capability. These housings are rugged and provide excellent mechanical stability for different mounting arrangements. Both room temperature operating and TE-cooled units are available. The thermal characteristics of the package are good enough that in many cases the TE units do not require additional heat sinking. Optimization of the gain and bandwidth is done at the time of order to specific user requirements and the output signals are compatible with signal processing electronics such as ADCs, lock-in amplifiers, oscilloscopes, and DVMs.
Options include: optical filters, filter holders, fiber-optic connectors and custom multi-stage amplifiers. Click here for part numbers |
Cyrogenic Receivers
|
The cryogenic receivers offer the ultimate in sensitivity for any given wavelength range as well as maximum immunity to EMI, microphonics, and accidental mishandling.
The standard EOS dewars, side-viewing or down-viewing, can be provided with built-in amplifiers for any of the photodiode or photoconductor components. Depending on the specific detector and sensitivity requirements, parts of the amplifier may be cooled along with the detector. These EOS modules are unique in the industry in providing the ultimate in sensitivity, EMI immunity, and low microphonic noise. The standard units contain switchable gains, BNC outputs, and shielded power connections. Custom options include offset control, additional gain control, and multi-stage amplifiers.
