brief introduction:Plano convex lens
Plane convex lens is normal focal length lens,One side is plane.,The other side is convex,Used to converge parallel light,Or converting point light sources into parallel light。Widely used in telescopes、Microscope、Collimator、Laser and Optical Fiber Products。
According to application requirements(Service temperature,Working wavelength and other conditions)difference,Flat convex lenses with various materials,IncludeK9Glass、Ultraviolet fused quartz(JGS1)、Calcium fluoride、Magnesium fluoride、Barium fluoride、silicon、germanium、Zinc sulfide,Zinc selenideetc.。
