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 find out more about our power supplies please

EOS categorizes the Receiver
Modules into three main sub-categories as follows: |
______________________________________________________________
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

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

Cryogenic
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.
