TE-cooled VGA InGaAs SWIR camera platform with USB3, Camera Link, GigE, analog, and HD-SDI model options.

High Sensitivity + Wide Dynamic Range

The SenS sensor supports linear CTIA operation for low-light sensitivity and logarithmic response for wide dynamic range imaging. This allows the same camera family to handle low signal levels, bright scenes, and applications where illumination can vary significantly across the field of view.

Multiple Interface Choices

Choose from USB3, Camera Link, GigE, analog video, or HD-SDI configurations. This makes the SenS 640 family suitable for laboratory use, machine vision integration, embedded systems, UAV payloads, and video-output SWIR applications.

Optional Gated Acquisition

Selected STP and STPE configurations support fast gated acquisition for pulsed laser imaging, time-resolved measurements, and range-gated SWIR applications.

SenS 640 TE-Cooled Camera Family Overview

The /640v-st/ page can serve as an inclusive product page for the SenS 640 TE-cooled SWIR camera family. The family uses a 640 × 512 InGaAs sensor with 15 µm pixels and spectral response from 0.9 to 1.7 µm. Models are available for interactive imaging, high-speed image acquisition, embedded integration, machine vision, video output, and gated SWIR imaging.

For best SEO and user clarity, this page now positions the SenS 640 platform as a full family of TE-cooled VGA SWIR cameras rather than only the USB3 SenS 640V-ST / 640V-STP models.

How to Select the Right SenS 640 Model

Select a SenS 640 model based on the preferred data interface, software workflow, integration requirements, and whether gated acquisition or onboard video processing is required.

USB3 Models

Good choice for laboratory imaging, R&D setups, and applications that need NITVision plus SDK support.

Camera Link Models

Recommended for deterministic frame grabber-based acquisition, high-speed integration, and OEM systems.

GigE Models

Useful for machine vision and networked imaging where cable length, Ethernet infrastructure, or PoE options are important.

Analog / HD-SDI Models

Designed for video-output applications, embedded systems, UAV payloads, surveillance, and display-oriented workflows.

Gated Models

Use STP or STPE versions when pulsed laser timing, range-gated SWIR imaging, or very short exposure windows are required.

HiPe Models

Consider HiPe SenS models when the application requires the high-performance variant of the SenS 640 platform.
