Power Sensors

Product catalog summary

High-Dynamic-Range Power Sensors

These sensors feature automatic seamless gain switching with a 30-µs transition time, eliminating the need for manual adjustments to view high-dynamic-range signals on an oscilloscope.
They offer up to 25-kHz bandwidth and a dynamic range of over 65 dB, suitable for general lab experiments.
The logarithmic analog output spans 70 dB, allowing a single 14-bit A-to-D conversion to achieve less than 0.01-dB resolution over the full range.
Models 2101 and 2103 are designed for applications requiring wide dynamic ranges, such as fiber alignment and absorption spectroscopy.
The sensors are temperature stabilized for accurate and stable measurements and feature a patented logarithmic-conversion circuit for seamless range switching.
Specifications include a wavelength range of 320–1060 nm for Model 2101 and 950–1630 nm for Model 2103, with user-selectable 3-dB bandwidths of 1, 5, and 25 kHz.

Ultracompact Power Meter

The Model 3803 is a handheld power meter designed for optical sources from 400 nm to 1064 nm, with a power measurement range from 0.5 µW to 1 W.
It features auto-ranging, peak sample and hold, and a built-in optical attenuator to protect the sensor from saturation.
The device is microprocessor-controlled with wavelength correction and displays measurements on an LCD screen.
Specifications include a ±5% calibrated accuracy and a maximum power density of 30 W/cm² with the built-in ND attenuator.

20-GHz Amplifiers

Models 1421 and 1422 are traveling-wave amplifiers designed to boost signals from high-speed photodetectors, suitable for use with spectrum analyzers and oscilloscopes.
The amplifiers feature a frequency response of 50 MHz to 20 GHz, with options for a low-frequency cutoff of 14 MHz.
Model 1421 provides an 8.5 dB gain (inverting), while Model 1422 offers an 18 dB gain (non-inverting).
Both models have a noise figure of 8 dB and input/output impedance of 50 Ω.
