The Nydar Shotgun Sight gained fame in 1945 for its use on… well, shotguns. Instead, it’s time to turn to the ground again for a look at small arms. The sight’s reticle could now adjust for lead.īut we’re not here to talk about the gargantuan reflex sights that were mounted into airplanes. In 1939, the British combined the reflex sight with a gyroscope that accounted for the plane’s velocity and rate of turn. When war broke out again, these sights were equipped with even better capabilities. In the 1930s, this technology became a little more widespread, and other airforces began adopting the same. However revolutionary this design was, it was applied mostly on a trial basis.īefore too long - and not long before World War II - French forces began adopting the reflex sights for their bombers and fighters. The gun operator could align this sight quite easily, without the need for proper orientation on older mechanical sights. It was bounced upward, appearing on the surface of a 45 degree beam splitter. Light was sent through a similar reticle-bearing lens, though this time from below. These sights, in contrast to Howard’s diminutive small arms modification, used electronic illumination. Curiously, his patent was used by the German military in the form of the Oigee Reflector Sight, developed by the optical firm Optische Anstalt Oigee in Berlin. Less than two decades after its premier, the reflex sight was being introduced to the military as a piece of speciality equipment for fighter aircraft in World War I. Reflex sights were by no means done with development, and Howard’s work was far from over. Nowadays, we’d know it as a closed reflex sight. You are now seeing your target and a reticle, simultaneously. This silvered glass bounces the shadow of the reticle onto the inside of the objective glass. Sunlight streams past this reticle and down onto an angled, silvered glass. This second objective window has a secret - a tiny reticle on the inner side of the glass. Meanwhile, the sunlight is streaming through the small window above the objective. No added magnification, and a relatively small circular window. Looking into the eyepiece, you’ll see whatever the reflex sight is pointed at. Now mount yourself up behind the optic and take a look through. Also, angle it a bit, to help the light enter directly from the sun. Throw a second small window up top, just above the objective end. A little boxier than the one you’re picturing right now, actually. Howard went to work combining a few simple elements to deliver a rather impressive product. This inventor took a different approach - a non-magnifying optic that used the sunlight itself. Illuminated reticles existed to some degree, though they required a candle be installed in the scope. Scopes were already in existence at this point, with magnifications as high as 20 power. In 1900, Howard premiered his latest invention - a reflective sight for small arms. Under the name of the Grubb Telescope Company, Howard went on to build refractor telescopes for a number of observatories across Europe, powered by his family’s electrically driven clock drives.Īt this point, I might say something like, ‘the sky’s the limit.’ Considering that Sir Howard Grubb already got his hands grubby building telescopes, it only seems fitting that something ground-level was his next endeavor. In 1864, he joined his family’s optical firm to start a life of serious telescope work. After leaving college without a degree, he went on to train as a civil engineer. Howard was born in 1844 in Dublin, to a family already steeped in telescopes. That’s all there is to it - a reflected aiming point of some sort that floats over the target, held aloft by a sort-of-mirror. Let that glass act a bit like a mirror, just like your car windshield does at the most inconvenient times. The theory behind reflective sights, known by names such as reflex and red dot, is remarkably simple. Today’s question is simple: If you saw a photo of someone using a reflex sight in the year 1900, would you think they were a time traveler? Before looking into the history of red dots, I certainly would have. This story starts with a question, as some stories do.
