Solution B – Second more complicated arrangement / solution was 'Biwa' (Bildwandler), which provided driver (installed on the front hull), gunner (installed on the mantlet in front of the gun sight) and commander (as in Solution A) each with one 30cm infrared searchlight (with range of 600m) and image converter.

This solution could be easily mounted on any type of armored fighting vehicle. Panthers with IR operated with SdKfz.251/20 Uhu (Owl) half-track with 60cm infra-red searchlight and Sd.Kfz.251/21 Falke (Falcon). From March to April of 1945, approximately 50 Panthers Ausf G (and other variants) mounted with FG 1250, saw combat service on the Eastern Front and Western Front. Solution A – Sperber (Sparrow Hawk) was made up of one 30cm infrared searchlight (with range of 600m) and image converter operated by the commander – FG 1250.From late 1944 to March of 1945, some Panzerkampfwagen V Panther Ausf G (and other variants) mounted with FG 1250, were succesfully tested. Two different arrangements / solutions were created and used on Panther tanks. In mid 1943, first tests with infrared night-vision (Nacht Jager) devices and telescopic rangefinders mounted on Panther started. In autumn of 1942, unit for use (infrared headlamp with viewer ZG 1221) with 75mm PaK 40 L/46 anti-tank gun was constucted and was also mounted on Marder II (Sd.Kfz.131). It operated in the upper infrared (light) spectrum rather than in the lower infrared (heat) spectrum and therefore was not sensitive to body heat.įG 1250 In 1936, AEG was ordered to start the development of infrared night-vision devices and in 1939, first successful prototype unit for use with 37mm Pak 35/36 L/45 anti-tank gun was constructed. The searchlight consisted of a conventional tungsten light source shining through a filter permitting only infrared light. This was all strapped to a Tragegestell 39 (pack frame 1939). As well as the sight and spotlight, there was a 13.5 kilogram (about 30 lbs.) wooden cased battery for the light, and a second battery fitted inside a gas mask container to power the image converter. The grenadier carrying this was known as a Nachtjäger (night-hunter). Haenel at Suhl, the weapons production facility. The ZG 1229 Vampir weighed in at 2.25 kilograms (about 5 lbs.) and was fitted with lugs on the StG 44 at C.G.
