Difference between aspheric lenses & spherical lenses:
Aspheric Lenses: Advantages & Disadvantages In a nutshell, aspheric lenses have the following advantages:
They provide a thinner profile
They are lightweight and comfortable
They could be fit into most frames so you have a wide choice of styles
They have a more natural and pleasing appearance
They don't make your eyes look too big or too small
They provide a better peripheral vision by eliminating distortion
Difference between aspheric lenses & spherical lenses:
We provide all kinds of customized optical lens which according to your drawings, sample products or detailed requirements. Any inquiry please feel free to contact us, thanks!
We can provide virtually any size, shape and quality required by the customer. The range covers more than 60 types including the following types in the visible wavelength range from 200 nm upwards:
- Band pass filters, which allow required ranges to pass through selectively
- Long pass filters, which block unwanted shorter wave ranges
- Short pass filters, which block unwanted longer wave ranges
- Neutral density filters, which have a virtually constant transparency especially in the visible range
- Conversion filters, which due to their spectral range increase or reduce the colour temperature of radiation sources
Materials
- Basic glass
- Ionically coloured glass
- Colloidally coloured glass

Applications
Optical glass filters are used in a host of different applications. Optical glass filters are significant components in industrial measurement, control and regulation technology through analytical measuring methods in production, research and development all the way to environment protection and medicine with which to permit or block the transmission of specific spectral ranges.
Filter Glass Types
- UG Black and blue glass which permits the transmission of UV light
- BG Blue, blue-green and bandglass
- VG Green glass
- GG Yellow glass which permits IR light transmission
- OG Orange glass which permits IR light transmission
- RG Red and black glass which permits IR light transmission
- NG Neutral glass with virtually constant radiation weakening in the visible range
- N-WG Colourless glass with different cut-off positions in the UV range and which allows IR and visible light transmission
- KG Virtually colourless glass with high transmission of visible light and absorption of radiation in the IR range
- FG Blue and brown coloured glass (conversion glass)
