For example, the varifocus imaging optic system IMM25-Z1830 has a zoom range from 18 to 30 degrees, a Φ25mm iris is used in this system and the zoon function is done by a combination of two achromatic cemented lenses. When a customer purchases IMM25-Z1830 from this E-shop, he/she will get these two achromatic cemented lenses.
Note: To get better imaging quality, the LED having smaller luminous surface is the preferred light source option, and a combination of two or three plane-convex lenses is also used as condenser.
