The Powell prism, also known as the line laser generation prism, is specifically optimized for the production of linear laser light spots. The Powell prism converts circular light spots into uniform linear light spots, providing a uniform energy distribution over the entire beam length. The Powell prism is an ideal choice for applications such as calibration and machine vision. These prisms offer multiple top-angle models.
UItraopto Precision Optics Co. Ltd can consistently supply this type of product through precise control of polishing, coating and bonding processes. It also accepts customized orders for various specifications of Powell prisms.

There is a uniform intensity distribution at the top of the entire line light.
Provide circularly polarized light ranging from 1° to 75°
Ultraopto’s Powell Prism is a high-precision optical component expertly engineered for uniform laser line generation, serving as a core part in laser alignment, industrial machine vision, laser measurement and various professional laser systems. Unlike traditional cylindrical lenses that produce uneven laser lines with bright centers and dim edges, our Powell Prism adopts an optimized wedge-shaped structural design and precision optical processing, which can convert a single laser beam into a highly uniform, low-divergence linear laser with consistent intensity distribution across the entire line, effectively improving the accuracy and reliability of laser-based detection and positioning applications.
We manufacture our Powell Prisms with advanced ultra-precise grinding and polishing technologies, implementing strict tolerance control over all critical optical parameters including prism apex angle, surface flatness, linear uniformity and laser divergence angle. Every Powell Prism is crafted from premium optical materials including N-BK7, Fused Silica and other high-quality optical substrates, selected for their excellent laser transmittance, high laser damage threshold and stable optical performance, which are adaptable to visible, infrared and ultraviolet laser wavelength ranges, and can withstand the high power of industrial laser beams to meet the diverse application requirements of professional laser systems. Our strict multi-stage production quality control system ensures that each Powell Prism meets international high-end optical manufacturing standards, delivering consistent and reliable laser line generation performance in the stringent working conditions of industrial production, scientific research, aerospace and biomedical detection fields.
Our Powell Prisms boast outstanding core optical advantages, with superior laser line uniformity that ensures consistent light intensity across the entire generated line, eliminating the bright spot and attenuation problems of traditional laser line generation components and improving the accuracy of laser scanning, alignment and measurement. The optimized optical design achieves low laser divergence, keeping the laser line clear and stable even at long working distances, and enhancing the adaptability of the product in different application scenarios. Through advanced surface processing and optical path optimization.
Our Powell Prisms realize high laser transmittance and low optical loss, maximizing the utilization of laser energy and reducing unnecessary light attenuation in the laser line generation process, while the high dimensional precision and angular accuracy of the prism ensure seamless integration with various laser systems, avoiding optical path offset and coupling errors caused by dimensional deviations and improving the overall stability of the laser setup. We also provide customized apex angle design and wavelength-specific anti-reflection (AR) coating services for Powell Prisms, with customizable line lengths and divergence angles to match the specific application requirements of customers' laser systems, and the durable vacuum-plated coatings further enhance the laser damage threshold and environmental adaptability of the product. In addition, the prism features a robust structural design, with excellent resistance to temperature changes, mechanical vibration and industrial field wear, ensuring long-term stable operation in complex industrial working environments and harsh outdoor application scenarios.
Ultraopto’s high-precision Powell Prisms are widely applied in a full range of professional laser fields that demand uniform laser line generation, including industrial laser alignment and positioning such as mechanical part assembly, electronic component welding and precision equipment calibration; industrial machine vision systems such as surface defect detection, dimension measurement and object recognition, providing clear and uniform laser reference lines for visual inspection; laser measurement and scanning such as 3D surface scanning, distance measurement and industrial topography detection; as well as medical laser equipment, aerospace optical sensors, laser teaching experiment platforms and outdoor laser positioning systems in the scientific research, medical and aerospace sectors.
