Description

Technical Field

[0001] The utility model relates to the technical field of vision lighting of automation equipment, in particular to a laser test bench. Background Art

[0002] A laser light source is a light source that emits a highly concentrated, monochromatic, and directional beam. Laser light sources have many unique physical properties that make them widely used in many fields.

[0003] For laser light source products, thickness and uniformity are key quality indicators. Testing these characteristics ensures that products meet specified standards and specifications. The thickness of the laser line reflects the focusing ability of the laser source. A thinner laser line means better focus, which is very important in many applications, such as precision machining, laser cutting, and laser marking. The uniformity of the laser line determines the uniformity of the energy distribution. Uneven energy distribution in the laser line can lead to poor processing results, such as localized overheating or uneven melting during laser welding or laser drilling.

[0004] Currently, when testing some laser light sources, the laser light beam is usually irradiated onto the inclined surface of the triangular block to form a laser spot. The thickness of the laser spot is judged by directly observing the size of the spot or the diffusion of the beam on the forming surface. However, visual observation lacks test accuracy and is prone to eye damage. Utility Model Content
