Attention

▶There is a direction to the Fresnel lens. Surface that is processed is equivalent to convex.
▶When used in laser, since diffracted light is generated in the step structure, some of the light will also leaked around the focused spot .
▶Characteristics as the lens is obtained in the range of φ50mm, but it is not guaranteed the accuracy of the focal length out of the scope of the clear aperture.
▶When rubbing strongly the processed surface of the fresnel lens, performance may be degraded. Please do not touch directly the surface.
▶When exposed to high temperature of 80°C or more, it is deformed and performance can be severely degraded.
▶Please do not use organic solvents such as acetone and chloroform.
It is dissolved and the step structure will be broken.
▶At the time of delivery, it is delivered that protection sheet is affixed to the surface. Please use it in stripped the protective sheet when using.
