Spark the desire to explore conference made by InfiRay Outdoor presented new equipment going beyond the usual thermal and night vision sights, which we wrote about just recently. The new products also include two observation devices that follow the latest trends in the thermal imaging market.

One of them are the Gemini GEH50R multispectral observation binoculars. In addition, the InfiRay Outdoor offer also includes a refreshed version of the Finder monocular - the FHR35R V2 - with a thermal sensitivity of NETD ≤20mK .

The GEMINI GEH50R

Even though InfiRay Outdoor is developing its offer of products from the Thermal+ line (combining thermal imaging with a classic optical channel), in the construction of the Gemini - multispectral binoculars in a classic layout - digital sensors were used, just like in competitive products of this class. The GEH50R model combines a thermal sensor with a resolution of 640x512 pixels (size 12 μm) and thermal sensitivity of NETD ≤25 mK with a 1920x1080 px sensor responsible for the daytime layer and digital night vision.

The device uses 50 mm (F1.1) optics for the thermal layer and 35 mm for the daytime with digital night vision one. The results in the thermal imaging having a base magnification of 4.1x (with digital magnification of up to 16.4x) and a 8.8°x6.6 ° field of view. The second channel allows observations with a minimum magnification 3.8x (digital magnification of up to 15.2x), maintaining a field of view of 9.4°x7.0°. The total detection range of an object the size of a human (thermal layer) reaches 2600 meters. Focus adjustment has been moved near the lenses and is done separately for each channel using intuitive knobs.

Various image variants are shown to the user with a frequency of 50 Hz on two AMOLED screens with a resolution of 1024x768 pixels each. Unlike some competing multispectral binoculars, the Gemini GEH50R allows to fuse both layers and present the user with a view tailored to their preferences (visible spectrum, thermal layer, fusion: backlight, edge selection and hot spot tracking).

It is also worth noting that the design of the binoculars allows to change the spacing of the eyepieces to better adapt to the different shapes and sizes of the user's face.

Between the two main lenses there two smaller ones. They contain a laser rangefinder module with a range of up to 1200 meters. The device has also been adapted to install an additional, external IR illuminator (the product includes a clamp and a flashlight operating at an IR wavelength of 940 nm) for observations using digital night vision in conditions of insufficient nightime illumination.

Naturally, there are additional functions, such as Wi-Fi connectivity, recording videos with sound (64 GB onboard memory), the ability to update the software and many others. The Gemini GEH50R is powered by two replaceable and popular 18650 cells, which allow to use the device for up to 12 hours. External energy sources are also supported via a USB-C port.

The new multispectral binoculars from InfiRay Outdoor weigh approximately 960 grams without the battery. It is protected against water in the IP66 standard.

The GEMINI GEL35R

Although only the Gemini GEH50R model was presented during the InfiRay Outdoor conference, examining the materials available at the manufacturer's website (including the user manual) reveals that the Gemini family will have a second, budget variant added soon

The Gemini GEL35R will be equipped with a thermal sensor with a lower resolution: 384x288 pixels (its other parameters remain unchanged) and 35 mm optics. This will change the base magnification and field of view of the thermal imaging layer: the available parameters are 4.8x-19.2x (using digital zoom) and a 7.5°x5.6° field of view.

This variant of the binoculars will be slightly lighter (approximately 900 g) and equipped with a smaller internal memory: 32 GB.

The FINDER FH35R V2

The last of the new hardware presented during the conference is refreshed version of the popular Finder series.

Compared to its predecessor, the most important information about the FH35R V2 model is the significantly improved of the NETD thermal sensitivity, which is now ≤20 mK. With a 35 mm lens and an F0.9 aperture, the new InfiRay Outdoor product becomes a serious competition for the best thermal imagers made by other respected companies (e.g. the  Telos LRF XP50 by Pulsar described by us in the first quarter of this year).

The thermal sensor used in the Finder FH35R V2 monocular has a resolution of 640x512 pixels (size 12 μm) and a refresh rate of 50 Hz . The basic optical magnification is 2x with the possibility of digital magnification up to 8x. The maximum field of view reaches 10.5°×7.9°, and the detection of an object the size of a human is possible at a distance of up to 1800 meters.

The image is presented to the user on an AMOLED screen with a resolution of 1024x768 px. The device is powered by two separate, dedicated batteries which together are sufficient for over 10 hours of operation (tested at 25°C). The thermal imager also has a built-in USB-C port.

Among the numerous functions implemented in the device, it is worth mentioning Wi-Fi connectivity, video and sound recorder (32 GB onboard memory), as well as an integrated LRF module with a range reaching up to 800 meters

The Finder FH35R V2 is a compact device that weighs less than 400 grams. It is been protected against water in the high IP67 standard.
