Aspheric lens surfaces allow single elements to achieve near-diffraction-limited performance even at large apertures (using plastic grade) , avoiding the complexity, bulk and reflection losses of multiple-element designs such as microscope objectives. It is now possible to produce plastic grade aspheric lenses economically with good figure and low tooling costs.
New precision moulding technology, and bulk demand for laser-diode collimators, now allows us to offer this range of plastic moulded lenses at a very reasonable costs. They are also ideal for laser focusing and beam expanders and for fibre input and output.
Although designed for specific laser wavelengths, our moulded aspherics performance will be practically as good over most of the visible and NIR range.
The plastics used are light weight and easily machined.
