Fast Goldeye G-033 with new InGaAs sensor and Cool version with enhanced sensor cooling added to the SWIR camera family.

Allied Vision introduces new models of its Goldeye infrared camera series. The Goldeye is a Short-Wave Infrared camera (SWIR) that exhibits sensitivity between 900 and 1,700 nm.

Goldeye G-033: Fastest SWIR camera with GigE Vision interface

The new Goldeye G-033 features the latest InGaAs image sensor technology. It offers the same sensor resolution as the Goldeye G-032 (640 x 512 Pixels). However, with its smaller pixel size (15 µm vs. 25 µm), it can be used with more affordable lenses.

The Goldeye G-033 stands out of the crowd of SWIR cameras with InGaAs sensors with its very high frame rate. The new camera delivers more than 230 frames per seconds (fps) at full resolution in 12 bit mode. Reducing the resolution to QVGA (320 x 240) allows for a frame rate over 900 fps. This makes the Goldeye G-033 the perfect choice for many demanding applications requiring high speed, such as inline inspection (e.g. hot-end glass inspection) or plastics sorting using hyperspectral imaging in the recycling industry.

Goldeye Cool: Enhanced sensor cooling for long exposure times

At VISION 2014, Allied Vision also unveiled the Cool version of the Goldeye for the first time. As a standard, all Goldeye models come with an active sensor cooling that ensures low-noise, high quality infrared images. The Goldeye G-032 and Goldeye G-033 are fitted with a fan-less Peltier element TEC1 (Thermo Electric Cooling), which can cool the sensor down by 30 K vs. housing temperature.

The new Goldeye G-032 Cool features a two-stage Peltier module (TEC2) and a nitrogen cooling chamber. It can cool the sensor down by up to 60K. This enhanced sensor cooling reduces the dark current noise and allows for very long exposure times up to 10 seconds. This capability is very useful in demanding industrial and scientific applications, for example in the semiconductor and photovoltaic industries in which inspection tasks performed, using photoluminescence, require long exposure times.

Industrial design and high image quality

As an expert for machine vision cameras, Allied Vision designed the new Goldeye for industrial conditions.

The standard housing of the new Goldeye cameras is very compact. With 55mm x 55mm x 78 mm, Goldeye is the smallest SWIR camera with Gigabit Ethernet interface in the market. The interface is compliant with the GigE Vision standard. As a result, the camera can easily be operated in combination with the most popular image-processing libraries. With Power over Ethernet, one cable is enough to power the camera and transmit image data over up to 100 meters.

The new Goldeye can sustain harsh operating conditions. The rugged housing supports an extended temperature range from -20°C to +50°C. It also features fitting screw threads on all sides but the rear to easily and securely mount the camera into an automated system. System integration is also made easier by the multiple trigger and synchronization possibilities given by the I/O port (2 in / 3 out) and the RS232 interface.

The larger Goldeye Cool models (80 mm x 80 mm x 90 mm) are tailored for particularly demanding applications requiring very high image quality and long exposure times.
