Then, there are the filter threads. Filters are thin glass or plastic plates placed in front of the lens to achieve specific effects, analogous to Instagram filters but in a physical form. Filter threads are quite short, requiring only 1.5 to 2 turns for attachment. Filters should be easily interchangeable and are, by nature, lightweight.

While amateurs might take the tripod thread for granted, professionals place significant emphasis on this component for a couple of reasons. Firstly, a professional setup, including a lens, can easily reach a price range of several thousand euros. Naturally, photographers want assurance that the tripod thread is reliable and won't allow their equipment to fall. Additionally, for long exposure shots, even the slightest movement can ruin a shot. The camera's mirror can cause vibrations when it flips up, which is why a stable tripod thread connection is crucial. As a result, many photographers don't rely solely on the manufacturer-installed components and prefer to craft their tripod threads.

Tripod threads have their own standard, DIN 4503 (Camera and Accessory Tripod Connections). However, their dimensions are so similar to the UNC thread that the two can almost be considered interchangeable.

The smaller tripod thread is primarily used in rangefinder cameras, Single Lens Reflex (SLR) cameras, medium format cameras, flash rails, quick-release plates, and tripod heads. In contrast, the larger tripod thread is used in most medium format and nearly all large format cameras, as well as most connections between tripods and tripod heads.

Though traditional lens threads have largely given way to bajonet connectors, there are areas where screw connections remain preferred. The C-Mount is a standardized lens thread introduced in the 1920s for film technology, and it's still widespread today. The lens thread has an external diameter of 1 inch with a pitch of 1/32 inch. The flange focal distance is 17.526 mm.

Cameras with interchangeable lenses, like SLRs, need a mechanism to secure the lens to the camera body. This connection must be stable, as dropping or misaligning the lens can cause significant damage. Moreover, this interchange should be quick and simple, making it practical for everyday use.

Let's start with a thread that can be easily overlooked due to its positioning - the tripod thread, located at the base of the camera body. Its role is paramount, as this tiny thread must provide secure support when using a tripod during photography.

In this blog post, we dive deep into one such highly specialized area: special threads in photography. Professional SLR cameras utilize unique thread types in two significant places. Can you guess where? We're talking about the tripod thread and the lens thread. Although, in the realm of lenses, a newer solution has been gaining traction for years. But, let's start at the beginning.

A tripod thread has a tough job. If you've ever held a DSLR camera, you're aware of their potential weight. Especially when paired with a large lens, the device can be quite heavy to handle freely. Tripods are used when the camera needs to remain particularly still, e.g., during long exposure shots. The weight rests on a small, inconspicuous screw connection. This thread must be resilient, especially as the center of gravity shifts forward with larger lenses. In fact, very large lenses have their own tripod thread for additional stability.

Drill chucks are required for holding drills and other insert tools. CNC drill chucks; drill chucks for hand-held machines; precision quick-action drill chucks, as well as tapered mandrels/insertable pins; reducing/expanding sleeves; adapters and accessories are available here for you to choose from.

Historically, lenses were always attached to the camera body using a screw thread. The M39 lens thread, often known as the Leica thread, is particularly famous. Nowadays, conventional lens threads like M39, M40, and M42 are less common outside the realm of analog photography. For most purposes, lens threads have been replaced by bajonet connectors, which are known for their ease of use, allowing photographers to change lenses quickly with a single hand motion.

The world of thread standards is a fascinating balance between standardization and specialization. In most applications, it's convenient to work with the same standards repeatedly, allowing your equipment to serve multiple projects. On the other end of the spectrum are the specialists. Thread standards designed for a very specific use-case and found only in that context.

An Optical Beamsplitter is an optic or optical device that is used to split a beam of light in two. Newport offers a wide variety of Beamsplitters in various shapes. Circular beamsplitters, plate beamsplitters and cube beamsplitters can be purchased for polarizing or non polarizing beamsplitting applications. Newport offers both broadband and laser line cube beamsplitters. These beamsplitters are made from high grade glass materials with laser grade surface flatness and surface quality and have a tighter tolerance on the splitting ratio. High damage threshold coating and quality substrate material allow them to withhold high laser pulse energy.
