Varifocal lenses feature adjustable focal lengths, offering the versatility of an “all-in-one” solution; when photographing cityscapes, photographers can capture stunning architectural images without the need to frequently switch lenses.
In cityscape photography, here are some creativ...
Surround-view lenses offer convenience for vehicle driving and are quite practical in parking and low-speed driving scenarios, but they are not omnipotent and have some noteworthy drawbacks in in-vehicle applications.
1.Image quality and visual distortion
The primary function of many in-vehicle s...
M7 lenses refer to lenses with an M7 threaded mount. They are common miniature lenses, small in size and light in weight, and are important in fields where space and weight are strictly limited.
The M7 lens is primarily used in miniaturized, embedded, and low-cost vision scenarios. Common applica...
Iris recognition technology is a type of biometric technology and is considered one of the most accurate and secure biometric identification technologies currently available. Compared with technologies such as facial recognition and fingerprint recognition, iris recognition has significant advant...
Modern CCTV lenses have a wide range of applications, being extensively used in public spaces, on streets, and in institutions such as schools, hospitals, and banks. Furthermore, surveillance systems have also become commonplace in homes.
CCTV lenses have a wide range of applications in home moni...
The principle of Time-of-Flight (ToF) is to calculate distance by emitting infrared light and measuring its round-trip time. Strong light (such as direct sunlight, spotlights, etc.) will generate a lot of background light, which will interfere with the echo signal of the emitted light and cause t...
The M12 fisheye lens is a compact, ultra-wide-angle lens widely used in small devices such as security surveillance systems, drones, and dash cams. In this article, we will explore the advantages of using M12 fisheye lenses in security surveillance applications.
Due to their unique optical proper...
Wide angle lenses, capable of capturing expansive scenes and creating unique perspective effects, are essential tools for photographing cityscapes at night, allowing for the inclusion of grand urban vistas, dazzling lights, and distinctive architectural lines in a single frame.
When composing a s...
Fixed focus lenses are an important tool for night scene photography, especially large-aperture fixed focus lenses. They can use shallow depth of field to highlight the subject, blur the background, separate the person from the background, and increase the aesthetic appeal of the image.
In night ...
Compared to traditional mechanical LiDAR, solid-state LiDAR lacks mechanical rotating parts, instead employing purely electronic or micro-electromechanical methods for beam scanning, with a focus on high integration, near-infrared transmittance, thermal stability, and resistance to environmental ...
Aberration refers to the deviation between the actual image formed by an optical system and the ideal image; it is an unavoidable phenomenon in optical system design.
Lenses with different focal lengths exhibit significant differences in the types and manifestations of aberrations due to variatio...
In the electric power industry, industrial endoscopes are key tools for non-destructive testing. They enable visual inspection of confined, high-temperature, high-pressure, or radiation-exposed areas inside equipment without disassembling, shutting down, or only briefly stopping the machine, allo...
