Photodetector-Amplifiers

The 710 Series are high sensitivity, low noise Photodetector-amplifier modules that offer the flexibility of incorporating a variety of silicon or InGaAs, PIN or APD Photodetectors. These amplifiers also offer the capability of integrating other detectors on a custom basis.

Laser Rangefinder (LRF) Receivers/Counters

Laser Rangefinder Receivers are designed for laser ranging applications in which high sensitivity and fast recovery are required. The hybrid versions are designed to meet MIL-STD-883D requirements. Either a silicon avalanche photodiode (APD) or an InGaAs PIN photodiode or APD is available to detect 1.064µm or 1.55µm wavelengths. Different receivers also are available to accommodate pulsewidths ranging from 0.5ns to 30ns FWHM.

Laser Spot Trackers

The Model 742DP is a new generation of laser spot tracker with wide flexibility for missile and platform tracker applications. The detector is temperature controlled and optimised for 1.06µm. Independent five channel noise detectors set the lowest thresholds to achieve long acquisition ranges for different background light and spot positions and special circuits resist sunlight blinding in any one or all quadrants. A range of N-type custom-designed detectors gives the highest performance at 1.06µm. A separate substrate allows the detector size or type to be optimised for your application.

This model comprises a hermetically-sealed temperature-controlled detector with built-in front-end electronics, mounted on a SMT board. A second printed board contains analogue and digital processing circuits. The individual channels are digitised with a high-speed A-D converter and output as a serial digital interface for steering. An adaptive threshold control allows optimum signal-to-noise operation and power management is used to reduce power consumption.

Optical Receivers

The 7510 is a high gain low noise APD-preamp optical receiver. The compact construction (modified TO-8 header) and PCB mounting capability make the 7510 ideal for miniature applications. The thermo-electric heater/cooler allows the highest performance to be achieved with an external control circuit.

Fibreoptic Links

The 732T/R Fibreoptic Link is designed for short-haul transmission of electrical signals for applications in which using electrical conductors are not appropriate. The 732T/R provides transparent transmission of AC and DC information without the undesirable effects of EMI pick-up noise. Units are sold as a transmitter/receiver pair.
