Lenses Selection Guide
These Lenses listed here are a single lens polished to a spherical shape different to multi-element lens for cameras or telescopes.
The performance is reduced to minimum with a wide range of applications at low cost.
| Application | Type of Lens | Features | Relevance information |
|---|---|---|---|
| Focus ・ Image formation | |||
| Focused laser beam | Plano Convex Lenses | Low cost. Small spot size. | High performance product → Achromatic Lenses |
| Collimated light | Spherical aberration is small. | High performance product → Achromatic Lenses |
|
| Illumination | Biconvex Lenses Plano Convex Lenses |
Compact. High numerical aperture. | High numerical aperture → Aspheric Lenses |
