InSb photoconductive detectors, InSb/InAs photovoltaic detectors, InAsSb photodiode

InSb photoconductive detectors are capable of detecting infrared light up to 6 m. InSb photovoltaic detectors can sense infrared light up to about 5.5 m, and InAs photovoltaic detectors to about 3.5 m. InSb and InAs photovoltaic detectors cover a spectral response range equivalent to PbSe and PbS photoconductive detectors, respectively, and feature higher response speed and better S/N.

InSb photovoltaic detectors

InSb photovoltaic detectors are high-speed, low-noise infrared detectors that deliver high sensitivity in the so-called atmospheric window between 3 and 5 m. Infrared light in the 5 m band can be detected with peak sensitivity and high response speed. There are two cooling types: a metal dewar type cooled with

liquid nitrogen and a stirling cooler type requiring no liquid nitrogen.							(Typ.)

Two-color detectors

Two-color detectors incorporate an infrared-transmitting Si photodiode mounted over a PbS/PbSe detector or InGaAs PIN photodiode along the same optical axis. This structure delivers a broad spectral response range. TE-cooled types maintain a constant temperature during operation allowing precision measurements with an improved S/N.

Photon drag detectors

The photon drag detector makes use of the “photon drag effect” in which holes created in a semiconductor by incident photons are dragged along in the direction of the photons, generating an electromotive force. Because of its sensitivity at 10.6 m, this detector is ideally suited for detection of CO2 lasers. The surface of the detector element is coated with a non-reflective material.

B7506-01 is a infrared detector module with preamp designed to detect infrared light by connecting to a DC power supply.

	Cable no.	Cable	Length	Note
			approx.
				Supplied with heatsink A3179 series.
		Coaxial cable (for signal)	2 m	When using this cable, make it as short as possible
				(preferably about 10 cm).
		4-conductor cable (with a connector)	3 m	Supplied with temperature controller C1103 series.
		A4372-05		This cable is also sold separately.
				This cable is supplied with the C4159/C5185 series amplifiers
				for infrared detectors, C3757-02, and infrared detector mod-
		4-conductor cable (with a connector)		ules with preamp (room temperature operation type).
			2 m	This cable is also sold separately. Besides this cable, the
		A4372-02
				A4372-03, which is a 6-conductor cable (with connector) sup-
				plied with “infrared detector module with preamp”, is also sold
				separately.
		BNC connector cable E2573	1 m	Option
		Power supply cable	1.9 m	Supplied with temperature controller
		(for temperature controller)		C1103 series
		Chopper driver cable	2 m	Connected to chopper
		(connected to chopper)
		2-conductor cable or coaxial cable	2 m or less	Prepared by user
		(for chopper power supply)

*1: Attach the bare wire ends to a 3-pin or 4-pin connector or to a banana jack, and then connect them to the power supply.

*2: Soldering is needed. When using the C5185 series amplifier, a BNC connector (prepared by the user, example: one end of the E2573) is required. *3: No socket is available. Soldering is needed.

Note: Refer to the datasheet "Accessories for infrared detectors" for detailed information about cables.
