An Aspheric surface reduces aberration and has a higher NA than spherical lenses,
Aspheric lenses are suitable for Relay lenses or Condenser lenses.
Isuzu Glass uses a manufacturing process by which softened glass is pressed into a die.
The advantages of the pressing method, compared to other mechanical processes,
include the ability to make many lenses without losing quality, greater design flexibility, and lower cost.
The focal length can be chanced by the spherical processing of the back side.
Lens coating, the change of diameter by cementing or thermally temper request are also acceceptable.
Please feel free to consult us!
