Ultra Micro Lenses
Molded aspheric glass lenses with 0.35 and over in diameter
Using high refractive index glass materials for our ultra micro lens allows an objective lens in a fiberscope to take a wider field of view.
- Objective lens used in a small diameter fiberscope, for the purpose of wider angle of view
|Diameter*1||φ0.35 mm and over|
|Center thickness||0.2 mm – 5 mm|
|Lens shape||Plano, biconvex, biconcave, and convex-concave (meniscus)|
