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.
● What fan angle of powell lens do we could manufacture?
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 °.
● Spot shape of powell lens
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.
● Waveband of powell prism
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.
● Dimension of powell lens
The main size of our prism products include dia. 9mm, dia.6mm, dia.40mm, square powell lens has 6mm*6mm, 6.35mm * 6.35mm, and 9mm * 9mm. We could also produce special size according to customer’ request.
● Capacity of our factory
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.
People also Ask
● What does a Powell lens do?
Powell Lenses, also known as laser line generating lenses, create straight, uniform laser lines by fanning out collimated beams in one dimension. The apex of each lens below features an acylindric curve that evenly redistributes the optical power of a Ø0.
● 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.
● 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.
● 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.
Welcome to select a powell lens from VY Optoelectronics Co.,Ltd.
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.
