Triple bonded lenses are composed of one low refractive index lens and two high refractive index lenses bonded together. Due to their completely symmetrical design, these lenses can be used interchangeably, reducing distortion and spherical aberration.
Triple laminated lenses are suitable for focusing and imaging magnification of collimated light beams.
The standard product specifications are shown in the table below, and we can also customize various specifications of triple laminated lenses for customers.
