Prism
The core uses of a prism include deviating light at a specific angle, while also enabling light deviation and image orientation adjustment. The way it interacts with light is entirely determined by its own design. When light enters a prism, there are mainly two paths of action: one is that light first reflects off one or more surfaces of the prism and then exits; the other is that light is directly refracted while passing through the prism substrate. As an example, the right-angle prism belongs to the former. When light enters, it first reflects off one of its surfaces, ultimately achieving a 90° light deviation. The wedge prism, however, belongs to the latter; since the thickness of its substrate varies, light deviates due to refraction when passing through. Prisms have the following types: dispersive prisms, reflective prisms, roof prisms, etc.

As a vital emerging sector of modern three-dimensional spatial economy, the low-altitude economy has become a new global growth driver. It covers a wide range of commercial scenarios, including UAV navigation and obstacle avoidance, precise airspace management, aerial mapping, low-altitude logistics distribution, security monitoring and emergency disaster rescue. Nevertheless, frequent extreme weather, complex terrain obstacles and increasingly dense low-altitude flight activities pose severe challenges to the safety and stability of low-altitude aircraft operations.
Laser pump sources are the core energy input component of solid-state lasers and laser amplifiers, and their performance directly determines the output power, beam quality and service life of the entire laser system. In scenarios such as industrial processing, scientific research experiments and high-end equipment, improper pump source selection will not only result in substandard system performance, but also bring a series of problems such as rapid device degradation and high operation and maintenance costs. This article sorts out the core selection logic and key pitfalls of pump source procurement, and provides selection references based on mature, mass-produced high-reliability products to help purchasers efficiently screen suitable products.
