The focal length of the lens describes the distance between the lens and the focused image on the sensor. As light passes through the lens it will either converge (positive focal length) or diverge (negative focal length), however within cameras the focal length is predominately positive. Shorter focal lengths converge the light more strongly (i.e. at a sharper angle) to focus the subject being imaged. Longer focal lengths, in comparison, converge the light less strongly (i.e. at a shallower angle) in order to focus the image.

This means that the distance of the focal length is determined by how strongly the light is converged by the lens in order to focus the subject being imaged. This, in turn, influences the angle from the horizonal of light that can be captured by the lens. This is known as the angular field of view (AFOV) and is required to determine the overall FOV. The AFOV is the angle between any light captured at the horizonal, and any light captured at the edge (as shown in Figure 2). If you have a fixed sensor size, altering the focal length will alter the AFOV and therefore the overall FOV. A shorter focal length provides a larger AFOV view, and therefore a larger FOV. The same is true but vice versa for longer focal lengths, as indicated in Figure 2.

3M™ Liquid Optically Clear Adhesive 2175 is a UV curing liquid OCA. It has good bonding strength to various display substrates such as polycarbonate and glass.

Field of view or FOV is the area of the object that is imaged by a microscope system. The size of the FOV is determined by the objective magnification. When ...

Field of view (FOV) is the maximum area of a sample that a camera can image. It is related to two things, the focal length of the lens and the sensor size. Figure 1 shows a comparison between the field of view and the size of the sensor. Assuming that the focal length of the lens is the same, the larger the sensor the larger the field of view.

Field of view defines the maximum area of a sample that a camera can image, determined by the focal length of the lens and the sensor size.

See how others are using our high-performance cameras, spectrographs and optics-based solutions to advance their research and application.

The focal length of a lens converges light so that the image of an object is focused onto the sensor. This determines the angular field of view, a parameter of the overall field of view. This is defined as the angle between any light captured at the horizontal and any light captured at the edge of the of the object. All of these parameters play a role in determining the FOV of a camera and can be measured using either trigonometry and the angular field of view, or via an optical test, in which a black body is utilized to create a virtual image

Solid State Drives (SSDs) have broken through as indispensable components, transforming storage and the systems they occupy. Speed, reliability, and efficiency have been revolutionised - but outside of this, the physical make up of their integration into modern computing systems have also seen physical change - all in the form of different SSD form factors.

This allows the FOV dimensions (i.e. vertical and horizontal distances) to be measured without knowing lens focal length or sensor size. The image created, including the target, is then displayed on a monitor, with the target image being a subset of the full image display. This allows the FOV to be approximated as:

U.2 was formerly known as SFF-8639 is a 2.5" SSD form factor, whilst the U.3 is an evolution of the U.2 form factor. These are designed specifically for enterprise and data centre environments. U.3 are backwards compatible with U.2.

Sensor size is determined by both the size of the pixels and number of pixels on the sensor. This can be optimized for each application, with larger sensors optimal for sensitivity limited applications, and smaller sensors optimal for resolution limited applications.

Part of the EDSFF family and rising to prominence in the market, E1.S and E1.L are bringing consolidation and flexibility to the market for data centres. What's more, they're playing a much heavier role in industrial use, specifically in edge devices and ADAS. E1.S and “S” stand for short is built just a bit longer than M.2, but wider for more NAND flash capacity. E1.L and “L” for long is often described as a rule form factor for denser storage environments.

Acton optics and coatings provide ultra-precision optical components and coatings with an emphasis on the UV/VUV spectral regions.

Mar 3, 2008 — Magnifying glass is used to look at tiny objects or fine print and they are available in various forms.

Figure 3 shows a simplified version of how these assumptions allow for AFOV calculation. By using trigonometry, the AFOV can be expressed as:

Part of the EDSFF family like the E1.S and E1.L, the E3.S has a growing use case for mainstream NVMe server storage subsystems. The E3.L is as above but mainly for systems and platforms that need max capacity for each “U” config that needs a deeper chassis.

The sensor size is determined by both the number of pixels on the sensor, and the size of the pixels. Different sized pixels are used for different applications, with larger pixels used for higher sensitivity, and smaller pixels used for higher spatial resolution (find out more on Pixel Size and Camera Resolution).

The 2.5" (inch) SSD is widely found and compatible with most laptops and desktops. Resembling HDDs, many users will look to this SSD when replacing a HDD, allowing for compatibility when upgrading. Using SATA technology and protocol, this traditional in nature as things stand right now SSD form factor is typically mounted into the SSD tray within a PC.

The gain relates the number of photoelectrons released to the gray levels displayed, and can be used to enhance contrast for low-light imaging.

Such form factors determine the shape and sizes that SSDs come in - much like the chassis of a car determining the compatibility with different roads. Like never before, understanding such form factors is key, not only deciding on the device such an SSD can fit into, but all nurturing the performance capabilities and potential applications.

A smaller version of the full-size SATA SSD, this SSDs can still be found in laptops and industrial applications - much like digital signage and PoS devices. Low on power consumption and a small form factor, it has a max bandwidth of 6 gigabits per second (Gbps). Comparing to M.2 SSDs, mSATA uses just SATA, whereas M.2 uses SATA and PCIe NVMe - as well as differences in speed, performance and sizes - all which weigh in M.2's favour.

To measure the FOV of UV, visible and infrared cameras, optical tests are commonly used. During the test, light is focused from a black body (an object that absorbs all light that falls on it) onto a test target at the focal place. By using a set of mirrors, a virtual image can be created that is at an infinitely far distance.

Where D is the full display image dimensions (either horizontal or vertical), and d is the target dimensions (either horizontal or vertical).

There are many subcategories of UV light, each which need different sensor requirements. These include both physical and chemical sensor changes.

2020124 — All I remember is the one in Barrington on Gloucester Rd between the railroad tracks and Clements Bridge Rd. It's still there, just not the Scientific branch.

Using NVMe as a technology with the PCIe protocol, has much higher data transfer speed advantages over 2.5" and also as a form factor, is much smaller - meaning it is far more appropriate for data centre and cloud servers, as well as use in IoT devices and embedded solutions. Due to its size and ability to be longer, thus slim and small form factor works in laptops and notebooks well.
