Optical Lens have many applications in range from the simple collection of the scanning of laser beams to precise imaging and image transferring. Optical Lens are classified as singlet, cylindrical, achromatic and ball lens according to the differentapplications.
Selecting the proper lens for your application requires making a number of choices. A few of the many considerations include: lens shape, conjugate ratio, f/number, transmission, wavefront distortion, scattered light, anti-reflection coating, and cost.
Plano Convex Lens | Plano Cocave Lens | Double Convex Lens | Double Concave Lens |
Meniscus Lens | Achromatic Lens | Cylindrical Lens | Rod Lens |
Ball Lens | Half Ball Lens | Aspheric Lens | Ring Mount for Lens |
Featured Material: For application in the visible and infrared up to about 2.1 μm, BK7 offers excellent performance at a good value. In the ultraviolet down to 195 nm, UV Fused Silica is a good choice. UV Fused Silica also has excellent transmission in the visible and infrared up to about 2.1 μm, better homogeneity, and a lower coefficient of thermal expansion than BK7. CaF2 and MgF2 offer high transmission in the deep UV, and they are excellent choices for deep UV excimer laser or infrared applications. Silicon and Germanium lenses are widely used in IR applications.
Material | Transmission Range | Cost | Features |
BK7 | 0.390~2.100nm | Low | High transmission for visible to near infrared applications, the most common optical glass |
UV Fused Silica | 0.160~2.100um | Moderate | Excellent homogeneity and low thermal expansion, high laser damage resistance |
CaF2 | 0.150~9.000um | High | High transmission for deep UV to infrared applications |
CZ Silicon | 0.120~100.0um | Moderate | High thermal conductivity and low density, excellent for infrared applications. |
Germanium | 1.900~17.00um | High | Excellent for infrared applications |
