Zoom
The lens of short focal length, which is thicker, has been made to a step structure and to a thin plate shape with the characteristics of the lens. It can be used as a substitute for the lens for a loupe and LED light.
◦Since it is processed directly on the acrylic plate of 2mm thickness, it is difficult to be deformed and the performance is stable.
◦There are four focal lengths offered from 5mm to 20mm.
◦Compared with the lens of the same focal length, it is lighter and lens will not protrude from the edge of holder.
Guide
▶This product is available with different focal lengths and sizes that are not listed on-line or in our catalog. Please contact our Sales Division with your requests.
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 may be deformed and performance can be severely degraded.
▶Please do not use organic solvents such as acetone and chloroform which will dissolved and damage the step structure.
▶At the time of delivery, it is delivered with a protection sheet affixed to the surface. Please remove this protective sheet before using.
