The HASO SWIR LIFT 160 provides the highest SWIR resolution and is a practical choice for the most challenging optical metrology applications. Moreover, this ...

The distance from the center of the lens to the image focal point (=image sensor surface) is known as the focal length. It is expressed in millimeter (mm) units. A lens with a short focal length is a wide-angle lens and one with a long focal length is a telephoto lens.

Attaching a 1.88x teleconversion lens to a 72 mm lens gives an angle of view equivalent to a 135 mm medium telephoto lens.

Ensenso 3D cameras enable precise classification and counting of objects. Identification is further optimised by additional colour information. Another ...

This is a lens used for close-up photography. A macro lens can shoot from a distance closer to the subject than a regular lens. The GXR interchangeable unit camera system has a camera unit with a 50 mm macro lens. Link to more information on GXR camera unit

With a zoom lens, when you turn on macro mode and move as close as possible while still keeping the subject in focus, the minimum distance to the subject and the size of the subject in the frame will differ depending on whether the lens is at a wide-angle or telephoto zoom position. With a wide-angle setting you may be too close and with a telephoto setting you may be too far away so adjust the focal length to find the one that makes it easiest to take the shots you want.

The phenomenon in which electromagnetic waves, such as light waves, vibrate in a preferred plane or planes; or the process of confining the vibrations to ...

It consists of four or five HVAC particulate air filters that form a cube and a box fan to draw air through the filters. The seams of the cube are sealed with ...

Even if the focal lengths of the lenses of two digital cameras are the same, the angle of view can vary depending on the size of the image sensor used in each. To make it easier to understand angle of view, focal length is often expressed as "__ mm equivalent," which means it has been converted to the 35 mm film camera format that has been historically the most common. Here on this site also, we state focal lengths that are converted into 35 mm film camera format.

6. If magnification is positive, the image formed is virtual and erect.

The angle indicating the width of the field included in the photo is called the "angle of view." A wide-angle lens has a wide angle of view and a telephoto lens has a narrow angle of view.

See Near and Far, SimultaneouslyHalo™ radar delivers an unprecedented mix of short and long range performance with its 4-foot open array, from just six metres (20 feet) to as far as 64 nautical miles. Monitor two distance ranges simultaneously in Dual Range mode, and take full advantage of Halo radar to keep an eye on faraway weather cells while monitoring channel markers and high speed watercraft up close. Pulse Compression technology means no compromises in detection at either range. Advanced digital signal processing helps to eliminate sea clutter, while Beam Sharpening technology provides enhanced separation between small or distant targets.Safety, Weather, and Bird-Finder RadarHalo radar delivers a comprehensive range of features to enhance your situational awareness and on-water safety. Monitor selected collision hazards with MARPA target tracking, or automatically highlight all approaching targets with the optional VelocityTrack™ Doppler motion-tracking upgrade. Keep watch on distant storm cells in Weather mode, your own real-time meteorological service. Halo radar also works as a powerful bird-finder, a must-have tool for sportfishing enthusiasts and pro anglers. Halo radar’s smart Weather and Bird modes require no manual tuning, just set the mode and go.Ready in an InstantCollision hazards won’t wait for your radar to start up – why should you? Halo radar’s solid-state technology is ready instantly from standby, and in just 16-25 seconds from a cold start. Avoid the 2-3 minute warm-up time associated with traditional pulse radar and trust Halo Radar to produce an immediate, accurate radar image when you need it. Halo radar’s low-power pulsed transmissions make it safe to run in anchorages and marinas, providing additional coverage in these high-collision-risk environments. Fast 48 RPM operation provides frequent position updates, while an advanced brushless motor and helical geartrain ensure quiet operation.
