The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields. Worldhawk are professional supplier for powell lens, in fact, we have already become the one of the main important suppliers of powell lenses in China. cooperation with us , you will get high quality products with reasonable price and products performance at the same time These Laser Line Generator Lenses, also known as Powell lenses, generate a straight, uniform laser line by fanning out a collimated beam in one dimension, as shown in the diagram above. The apex of each lens features an aspheric curve that evenly distributes the optical power, resulting in an intensity variation of less than 25% over the center portion of the line. You will get more even energy distribution along the laser line than using the rod lenses and lenses.
Long pass filter allow the longer wavelength throught, and cut off the shorter wavelength.These filter mainly used in Beauty equipment, police multiband testing instruments, strong light flashlight, stage lighting shade, four-wheel, iris recognition system, face recognition attendance device, optical instruments.
