Our company produces unique, individually-made micro optical lenses. We produce the front-side lens and the so-called sharp lens completely manually; however, our speciality is spherical radius optics. Our special equipment fleet is handled by our team of professional experts: former employees of the experimental facility of the legendary MOM, as well as their students. Owing to their thoroughness and precision, the lenses manufactured by us are used in medical instruments, experiments, telecommunications and in industrial laser technology all over the world.
PRODUCTION OF MICRO OPTICAL LENSES
Image quality in case of various optical imaging systems (cameras,telescopes, microscopes, etc.) depends on the finish of the optical lenses used. An optical lens is a refracting medium, usually bordered with spherical surfaces and generally made of glass, which refracts incoming light rays in the required direction, depending on the type, shape and configuration of the lens. Lens quality is determined by its base material, its processing and the quality of surface treatment.
SPHERICAL RADIUS OPTICS
Our company manufactures unique and individually-made micro optical lenses by hand, with our focus being on the field of spherical radius optics. We mainly produce the optical elements of endoscopic equipment designed for medical, therapeutic and technical use.
Single- and double-sided lenses, front lenses, menisci, achromates, masked optical elements, unique lenses and lenses of compound optical systems, the radii of which extend from 0,500 mm to flat surface, with their diameter ranging from 0,600 mm to 12,000 mm.
Due to the sizes of the lenses we make, series production is not possible. The starting point of manual production is that lens radius should be larger than half its diameter, but less than the entire diameter.
We process the lens on the lapping machines by hand, using diamond tools of various fineness. Workpieces are secured using either black tar adhesive or a manual gripping tool according to the technological specification. Afterwards, we define the approximate centre thickness of the lens using a lapping/stocking tool, as well as form its proper radius of necessary (based on lens type and the Customer's requirement). Then, we use ever-finer tools to create the proper lens surface with the ideal centre thickness before polishing is carried out. The number of polishing steps applied and the grain size of the polishing material are determined by the characteristics of the glass used. Due to the 1/1000 mm precision measurements done during manual lapping and the entire work process, we are able to polish highly accurate lens surfaces. The lens surface is not yet transparent after polishing; similarly to mottled glass, it is translucent. Therefore, the workpiece is further processed on the polishing machines.
The polishing machine polishes the lens surface using the appropriate polishing material in 3 steps until the lens is smooth. During the process, we supervise the lens parameters based on the criteria supplied (rings, colour, surface, etc.)
The lenses are continuously checked visually under a microscope, which aids primarily in spotting surface defects. The processed lens is then placed on an equivalent etalon lens that has a negative relative curve; thereby, we can determine the deviance of the lens surface from the correct or etalon surface to a high accuracy (ca. 1/50000 mm) based on the shape and form of the interference rings visible on the boundary surface.
The finished lenses are cleaned, and following quality checks (which also include the interferometric inspection), they are packaged and dispatched to our clients.

Contract and order
PLACING YOUR ORDER
In order to prepare our offer, it is essential that we receive both the blueprint of the micro optical lenses complete with dimensions and the filled-in technical data sheet required for the production process. When filling in the data sheet, it is important that parameters be supplied to 1/1000 mm accuracy because our experts carry out their tasks to 2/1000 mm accuracy.
Apply Technical Data Sheet
Once our offer is accepted, we draw up the supply contract that contains the agreed production price, any incidental advance payment, the agreed deadlines and the method of transport. This ensures that our partner does not bump into any hidden costs. Please send your order with an official signature in scanned format to one of our colleagues' e-mail address. Once manufactured by the deadline, the micro-optical lenses are packaged inside purpose-built storage racks that prevent surface and other defects from occurring.
The carefully prepared package is delivered by one of the internationally-acclaimed package delivery companies (TNT, UPS, DHL, FedEx, etc.) to the customer's address.
We can provide our long-standing partners with significant discounts, depending on the amount ordered monthly and the duration of the contract. Therefore, our partner (whether an end user or a dealer of the micro optical lenses produced by us) has the possibility to significantly reduce the acquisition price.
