● How does a laser line generator work? A cylindrical lens is a round bar or cross section of glass through which the collimated laser light passes and then spreads into a fan beam to form a line.

The divergent angle determines the length of the line when the laser is at a certain distance, The range for angle of powell lens we could process is wide, from 3 degrees-120 degrees, the current fan angle we are producing are 3 °, 4 °, 5 °, 7 °, 10 °, 15 °, 20 °, 22 °, 30 °, 35 °, 45 ° , 55 °, 60 °, 70 °, 72 °, 75 °, 80 °, 82 °, 90 °, 100 °, 110 °, 112 °, 115 °, 118 °, 120 °.

Monthly output of powell lens is 8,000 pieces, for regular small batch orders of 100 pieces are usually shipped within 2 weeks. In addition, there are tens of thousands of stocks to meet customers’ urgent needs.

● What does a line laser do? LINE LASERS: A line laser projects an accurate horizontal or vertical illuminated line onto the surface at which the laser is pointed. Use line lasers indoors when installing cabinetry, tile, a drop ceiling, or for basic leveling. They can also be used outdoors when framing or installing a deck.

Beam tracing is an extension of ray tracing that constructs beams around the central rays radiating from a source. Typically, a fan of such beams is used to represent a point source and the field at any given location is computed by coherently summing all contributing beams. On a slightly superficial level, one points to the following key benefits: (1) improved accuracy because the beams smooth out singularities of the ray-theoretic field, and (2) algorithmic advantages because eigenrays precisely connecting the source and the receiver do not need to be identified. One may argue about these considerations; however, beam tracing methods have emerged as a very important class of methods for computing ocean acoustic fields. Interestingly, the published literature has not kept up with the numerous advances in beam tracing, including algorithmic developments that are important to efficient and robust implementations. Furthermore, there are quite a few variants of beam tracing algorithms with very different characteristics. This article discusses these variants, significant advances in practical implementation, and performance characteristics.

● What is a line lens? The A-Line™ lens alignment system makes mounting, aligning, and focusing lens groups fast and easy. The front of each lens mount has a special 6 mm alignment hole, which can be used with GR Series Guide Rods such that several A-Line lens holders can be mounted together in a self-aligned row.

VY Optoelectronics Co.,Ltd. manufacture powell lens with different shape of spot and various dimension, spot shape of laser generator lens processing here include round spot, oval spot, square spot, rectangular laser spots. The size of the spot is 0.5mm-18mm. It is very important that the laser spot size matches the prism, a perfect match will result in a uniform line.

VY Optoelectronics Co.,Ltd. produce high quality Powell lenses designed for all manner of machine vision applications, from automobile assembly and food manufacturing to bio-medical applications. Our careful quality control ensures that all parameters of your lens fall within tight specifications, and will perform consistently in industrial conditions. The fan angle of your Powell lens is determined by the index of refraction of the substrate used and the roof angle of the lens. It describes how wide an angle the laser beam is fanned out over. Powell lens is limited by the line used as input, and it is important to select a lens designed for the laser beam width you intend to use. If a Powell lens optimized for a specific laser width is used for a narrower laser, the resulting line will display fading at the ends. If a Powell lens is used for a wider laser line, the resulting line will display increased intensity toward the ends.

We are open to discuss custom options that might be a closer fit to your application. Our team of engineers would be happy to work with you to determine the Powell lens that best fits your needs, and our factory has over 10 years of optical manufacturing experience ensures that we can both design or produce powell lenses that perform best for your application.

The used waveband can’t be mixed for high-precision prisms, VY accept clients to customize prisms for a wide range of applications. At present, the prisms we manufacture with waveband of 405nm, 450nm, 532nm, 635nm,650nm, 660nm, 760nm, 808nm, 850nm and 950nm etc.

A Powell prism is also known as a laser linear generator lens, convert laser beams into uniform, straight lines. Unlike cylindrical lenses, which generate Gaussian beam profiles with hot-spot center points and fading edges. Powell Lenses provide an even distribution of energy along the length of the entire line.
