Double Aspherical Lenses
- Designed for 1X Magnification
- Ideal for Finite Conjugate Applications
- 10 to 50mm Diameter Options
Double Aspherical Lenses feature two aspherical surfaces, reducing optical aberrations and improving image quality. These lenses offer superior performance in focusing and light transmission, making them ideal for high-precision optical systems. Common applications include laser optics, imaging, and medical instruments. Made from high-quality optical materials, they ensure excellent durability and clarity. Custom sizes and coatings are available to meet specific requirements.
Advantages of Double Aspheric Lenses
- Flatter and thinner than standard High Index Lenses as they have been surfaced on both sides
- Lightweight & durable
- Double Aspheric Lenses are available for both single vision & varifocal
- Can be tinted and made into Sunglasses
- Double Aspheric Lenses can be fitted into any type of frame including rimless and semi rimless
- Double Aspheric Lenses reduce the eye magnification or reduction problem some people have with stronger prescriptions
- Perfect for everyday wear including sporting activities.
Disadvantages of Double Aspheric Lenses
- Even with a good quality scratch resistant coating, care still needs to be taken as plastic lenses are easier to scratch.
- For stronger prescriptions, the overall result will not be as thin as Glass High Index Lenses.
