Aspheric lenses are highly efficient, low f/number light
condensers. They can be used to collimate or focus lamp output or
to collect radiation from a distant point and condense it onto a
detector surface. They are ideal for use in illumination systems
where it is often necessary to collect and/or focus as much light as
possible. Compared to plastic lenses, molded glass aspheric
lenses will operate over a much broader temperature and humidity range
without performance degradation. Because of these advantages,
molded glass lenses are often used in products such as projector
illumination systems and optical fiber systems.
These aspheric condensers are molded from high quality B270 optical
glass or Pyrex® heat-resistant glass. They are supplied
either uncoated or multi-layer AR coated, and heat treated or heat
toughened, if required.

| Overview |
 Focus on performance. YMT lenses are commonly fabricated from laser grade substrates such as fused silica, BK7 glass or optical grade sapphire. We are capable of fabricating a wide range of lens shapes and sizes to suit virtually any application. |
 Single and multilayer coatings. In addition, we offer advanced coating services that is well-integrated into our production line for an economical total solution. |
- Spheric. A variety of converging and diverging lenses.
- Achromatic doublet. Reduce chromatic and spherical aberration.
- Cylindrical. Uni-dimensional converging and diverging lenses.
- Aspheric. Eliminate spherical aberration and dramatically improve performance.
- Ball. Fiber/laser coupling and collimation.
