Optical Lens Manufacture
Kingsview Optical, a reputable and reliable precision optics company established in 1996, has garnered a rich history of delivering exceptional quality in the UK market. Our expertise lies in manufacturing optical lenses that cater to a wide range of requirements, ranging from micro lenses with a diameter of 0.8mm to large lenses with a diameter of 200mm.
Whether you need custom optical lens designs or already have a design in mind, we are here to help. Our team is experienced in producing prototypes and catering to high volume production, ensuring your specific needs are met. With a focus on precision and excellence in optics, Kingsview Optical strives to be your trusted partner in the industry.
CNC Optical Polishing
Our investment in CNC lens manufacture demonstrates our commitment to producing high-quality precision optics here in the UK. The addition of the 30 and 80 Optotech CNC lens lines marks a significant advancement in our capabilities. One major advantage of CNC polishing is the consistency it provides, allowing us to replicate difficult lenses accurately and efficiently. This means we are now better equipped to handle large batch sizes. Additionally, the cost of manufacturing custom lenses using CNC technology is more affordable compared to traditional cast iron tools. We are able to manufacture custom tooling to accommodate specific design requirements, thanks to our in-house metalwork manufacturing capabilities. This not only speeds up deliveries but also reduces costs. Overall, our investment in CNC lens manufacture enhances our precision optics capabilities, enabling us to deliver exceptional products.
Conventional Optical Polishing
Kingsview is also able to manufacture optical lenses using conventional polishing methods.
Kingsview bought a number of famous UK optics companies’ assets when they unfortunately went out of business, such as Achro Optics, Precision Tool and Intsruments (PTI), Cowley Level and Optical Instrument Balham Ltd. The acquired tooling and test plates of these companies means we have a large range of radii which you can base designs around incurring no tooling charge. This can be very useful in price when making very small quantities and prototypes.
Optical Assembly and Cementing
The lenses can be assembled in housings in our clean room assembly areas. We also cement optics using our air bearing centration table to ensure the highest standard of accuracy is achieved using Loctite or Norland adhesives.
Optical Coating
We also offer full optical coating for our lenses which we do ourselves from simple single layer to more complex multilayer coatings depending on your requirements.
Custom Optical Lens Capabilities
| Size: 0.8mm to 250mm |
| Diameter Tolerance: ±0.01 mm |
| Decentration (wedge): ± 10 second |
| Irregularity: λ/10 |
| Spherical Error: 0.5% of radius or better |
| Surface Quality (Scratch/Dig): 10/5 |

Custom Prisms
Kingsview makes prisms to any shape or size with the smallest currently made at 0.5×0.5 mm right angles. Over many years we have produced a standard range of periscope prisms for the British Challenger Tank and the M2 Abrams and were supplied to Helio Mirror Company. We are able to produce angles better than 10 seconds and can be confirmed with Rank Taylor Hobson auto collimators. We can also pitch polish to exacting flatness which can tested on a Zygo interferometer and mirror coat or A/R coat specific faces.
Example Prisms: Roof prisms, Penta prisms, Cube beam splitter, Right angle or whatever you require.
Custom Optical Prism Capabilities
| Size: 0.5mm to 400mm |
| Angle Tolerance: 10 Arc Seconds |
| Dimensional Tolerance: ±0.01mm |
| Surface Quality (Scratch/Dig): 10/5 |
| Flatness: λ/10@633nm |
Custom Filters
Schott, O’Hara, Kopp are the main suppliers of material for filter glasses used for a myriad of sets the world over. Kingsview has stock of many and can fabricate filters to any shape and size to suit your needs. This can include mechanical mounting cementing combining with vacuum coatings to form antireflection or bandpass filters. To test performance we use Parker Elmer Lambda 19 Spectrophotometer.
The types of industry we have produced filters in the past include military such as night vision applications and medical applications.
Custom Mirrors
We can produce spherical plano and cylindrical mirrors to virtually any shape or size. With custom coatings to meet your requirements be it front surface aluminium to full dielectric wavelength specific.
Custom Windows
At Kingsview we are able to manufacture windows of virtually any shape or size. We have a CNC edger and through use CAD/CAM we can profile very complex shapes fairly routinely.
