NXIR WaferOpto Diode Corporation, an ITW company, has introduced a range of silicon photodiodes designed specifically for back-facet laser-monitoring applications that require improved performance in the near-infrared (NIR) spectrum from 700nm to 1100nm.

ODC’s NXIR-family expands the company’s popular high performance SXUV and UVG photodiode series designed to maximise measurement repeatability and reliability in high-powered UV laser-monitoring systems with affordable products optimised for near-infrared wavebands.

The NXIR-RF36 and NXIR-RF70 near-IR / red-enhanced models offer reduced footprints and are ideally suited for integration with semiconductor lasers notably, Fabry-Perot (FP), distributed feedback (DFB), and vertical-cavity surface-emitting lasers (VCSELs).

The new devices have high responsivity of 0.65A/W @ 850nm, low capacitance of 5pF at 0 Volts, and high shunt resistance, greater than 200 MΩ.

The NXIR-RF36 has an active area of 0.36mm² while the NXIR-RF70 is 0.70mm². Both detectors are available in either waffle pack or dicing tape for high-volume shipments.

Opto Diode’s third device in the series, the NXIR-5W, is designed for high power laser monitoring that requires higher responsivity in the NIR spectrum. It can be utilised with Nd:YAG lasers used in biological, dental, and medical equipment, plus fluid dynamics, manufacturing, and military applications. The NXIR-5W has high responsivity of 0.45A/W at 1064nm with low reverse bias voltage of 10V, low dark current of 1nA, and low capacitance of 10pF.

The NXIR-5W is available in a hermetically-sealed, standard two-lead TO-5 package.

Our LED range spans the spectrum from UVC to the near infrared (NIR). We offer a wide range of LED components as well as engaging with customers to develop bespoke LED-based solutions incorporating LEDs, thermal management, drive/control electronics as well as monitoring and alarms.

We also supply single- and multi-mode laser diodes and modules from 450nm to 1,850nm as well as steady-state and pulsable thermal IR sources with blackbody output from 1 to 10µm.

For detection, we have visible and NIR-enhanced silicon photodiodes and a range of UV-optimised silicon photodiodes with responsivity down to 0.14nm — suitable for UV/visible spectrometry, extreme UV laser monitoring and direct ion/electron/X-ray photon detection.

Our range of silicon photomultipliers comprises true solid-state alternatives to conventional vacuum tube PMTs, avalanche photodiodes (APDs), Geiger-mode APDs and even silicon photodiodes in many low-light & high-speed applications such as scintillator-based radiation detection/imaging, fast fluorescence and LiDAR.

We also offer readout electronics for SiPM arrays using in medical imaging and radiation monitoring applications.

For longer wavelengths we offer a range of Lead Salt detectors with Lead Sulphide (PbS) covering 1-3.1µm and Lead Selenide (PbSe) from 1-5.5µm.

Our range of liquid-crystal based optical components includes Fast Optical Shutters, Fast Polarisation Modulators, Variable Polarisation Rotators and variable Neutral-Density Filters.

Finally we are pleased to introduce compact Czerny-Turner spectrometers and ultra-compact MEMS-based microspectrometers from OtO Photonics. OtO’s “SmartEngine” series of C-T spectrometers are the world’s highest selling spectrometers for OEM applications whilst their proprietary MEMS-based “Advanced UltraMicro” series are the smallest spectrometers at just 6cm³.
