Periscope Pro 3.3.1 LINK

The 24mm T14 2x PeriProbe not only inherits all the great features from the 24mm T14 2x Probe lens, a new tube with periscope is now also included. The new 90 Periscope tip unlocks countless new exciting movement. The 85 AoV and a very close 2cm working distance help created the bug-eye perspective. The 2x magnification allows for capturing subjects of different sizes with details. Users could poke the long and waterproof barrel into a tight space and underwater to obtain a unique perspective. The LED Ring Lite provides an extra light source. Users could also switch the 90 periscope back to the 0 straight scope. The lens could rotate 360 along the axis by unlocking the orientation ring. Additional accessories can also be mounted at the tip of the lens through the 1/4 screw hole.

Periscope Pro 3.3.1

Laowa 24mm T14 2x Periprobe is dedicatedly designed for Full Frame sensors. It hesitates all the features from Laowa 24mm f/14 2x Probe and adds a whole new periscope characteristic. The lens gives you a new perspective and improves flexibility in terms of setups and camera operation.

The Lens Support (for 15mm LWS Rod) is specially designed for 24mm T14 2x PeriProbe for extra stabilisation of the lens barrel. It is compatible with both direct view module and periscope module. *It is not usable on the original Probe. *

Most large submarines consist of a cylindrical body with hemispherical (or conical) ends and a vertical structure, usually located amidships, that houses communications and sensing devices as well as periscopes. In modern submarines, this structure is the "sail" in American usage and "fin" in European usage. A "conning tower" was a feature of earlier designs: a separate pressure hull above the main body of the boat that allowed the use of shorter periscopes. There is a propeller (or pump jet) at the rear, and various hydrodynamic control fins. Smaller, deep-diving, and specialty submarines may deviate significantly from this traditional design. Submarines dive and resurface by means of diving planes and changing the amount of water and air in ballast tanks to affect their buoyancy.

Submarines could not be put into widespread or routine service use by navies until suitable engines were developed. The era from 1863 to 1904 marked a pivotal time in submarine development, and several important technologies appeared. A number of nations built and used submarines. Diesel electric propulsion became the dominant power system and equipment such as the periscope became standardized. Countries conducted many experiments on effective tactics and weapons for submarines, which led to their large impact in World War I.

A raised tower on top of a standard submarine accommodates the periscope and electronics masts, which can include radio, radar, electronic warfare, and other systems. It might also include a snorkel mast. In many early classes of submarines (see history), the control room, or "conn", was located inside this tower, which was known as the "conning tower". Since then, the conn has been located within the hull of the submarine, and the tower is now called the "sail" or "fin". The conn is distinct from the "bridge", a small open platform in the top of the sail, used for observation during surface operation.

Among the pioneers of this alternative solution was the very first submarine of the Swedish Navy, HMS Hajen (later renamed Ub no 1), launched in 1904. While its design was generally inspired by the first submarine commissioned by the US Navy, USS Holland, it deviated from the latter in at least three significant ways: by adding a periscope, by replacing the gasoline engine by a semidiesel engine (a hot-bulb engine primarily meant to be fueled by kerosene, later replaced by a true diesel engine) and by severing the mechanical link between the combustion engine and the propeller by instead letting the former drive a dedicated generator.[73] By so doing, it took three significant steps toward what was eventually to become the dominant technology for conventional (i.e., non-nuclear) submarines.

During World War II the Germans experimented with the idea of the schnorchel (snorkel) from captured Dutch submarines but did not see the need for them until rather late in the war. The schnorchel is a retractable pipe that supplies air to the diesel engines while submerged at periscope depth, allowing the boat to cruise and recharge its batteries while maintaining a degree of stealth.

While the snorkel renders a submarine far less detectable, it is thus not perfect. In clear weather, diesel exhausts can be seen on the surface to a distance of about three miles,[82] while "periscope feather" (the wave created by the snorkel or periscope moving through the water) is visible from far off in calm sea conditions. Modern radar is also capable of detecting a snorkel in calm sea conditions.[83] 041b061a72
