Explore InGaAs/InP detectors for infrared monitoring, analytical instrumentation and SWIR optical sensing. Choose the wavelength class, geometry and package around your measurement.
Guide familiesThe supplied InGaAs guide describes principally 600–1750 nm for its 1.7 µm class and 800–2600 nm for its 2.6 µm class, with model-dependent limits. A cutoff class does not imply constant responsivity or suitability at every wavelength.
Explore Optrans 1.5 mm and 3.0 mm active-area options for optical systems with a larger light spot or greater alignment tolerance needs. A 5.0 mm active-area device is in development; share your requirements to discuss its potential fit.
Select the detector around your actual measurement wavelengths and optical footprint, then balance light collection against dark current, capacitance and bandwidth. The 2.6 µm designation is a cutoff class, not a guarantee of uniform responsivity or high sensitivity at the cutoff.

Size labels identify product interests, not package dimensions or a confirmed geometry. Confirm the drawing, specifications and commercial status with engineering.
Begin with the measurement task, then match the detector to the actual wavelength, signal and operating conditions.
Monitor light output, optical power or beam position in an instrument or control system. Match detector response, active area and speed to your source and optical layout.
Explore photodiode solutions for non-invasive optical sensing concepts targeting glucose, hemoglobin and tissue oxygenation. Photodiodes detect light returning from or transmitted through tissue; estimation of blood-related parameters depends on selected wavelengths, system design, calibration and clinical validation.
Application concepts, not validated diagnostic claims. Detector material and configuration must match each measurement method; a single PD is not assumed to support all three.
Build around the wavelength range and signal levels of your optical measurement or analytical method. Review noise, linearity, bandwidth and detector geometry as part of the instrument design.
Explore near-infrared measurements using material-absorption and reference wavelengths. Detector selection, illumination, calibration and optical geometry together determine system performance.

Detector choice depends on the measurement wavelength, collection optics and operating conditions, with calibration and application-specific validation required.
