dopa – for now 25 years we are your competent and internationally established partner for the development and production of diamond tools , the design of whole production processes and a specialized contract manufacturer for high end flat optics made out of different materials like optical glass, sapphire, ceramic, fused silica etc.
At this we have specialized us on the processing of optical glass, special ceramics and crystals. Our tools distinguish themselves by the fact that they produce also at high stock removal rates very fine, homogenous and scratch free surfaces, which have nearly no sub surface damage. This leads in the following manufacturing steps to a decrease of generally minimum 35 % of your polishing time. Furthermore it raises your products quality and stabilizes remarkably your processes. With their low wear our tools enable you moreover to produce very flat parts.
We own in our Berlin test laboratory most different grinding and polishing machines plus a wide range of measurement instruments. On those machines, that depict the state of the art technology in multiple industries, we run machining trials under real production conditions and optimize the tools and processes already here so far, that they can be implemented in our customer’s production as a complete system.
Improving existing technologies or visualizing whole technology changes as for example from lapping with loose abrasive to fine grinding or from polishing with diamond slurry to super fine grinding can be shown here while considering all economical and technological aspects. Using this our customers can cut down the long, hard and cost intensive implementation of new technologies at their end to a minimum or save it fully. Furthermore they are able to react much faster to changing market needs while not interrupting their running production. To push your borders we gladly assist you with our funded knowledge in choosing and making the right tools for your application.

- luminous intensity,
- luminous flux,
- peak or dominant wavelength,
- colour coordinates (in compliance to CIE standards)
and additional in in ultraviolet and infrared:
- radiant intensity and radiant flux (radiant power).

Degradation measurements and burn-in (in compliance to MIL standards) are performed with special test benches at different forward DC and pulse currents.

EPIGAP offers a fully integrated service from design and development to production in order to meet market requirements. Fast acting, flexibility, high-performance, high-reliability and cost-effective design make the difference for us to realize customer´s success.

iris-GmbH infrared &amp intelligent sensors is a developer and manufacturer of sensor components and products for Automatic People Counting. The main product IRMA (InfraRed Motion Analyzer) is a passenger counter for public transport. The sensors will be installed above the vehicle doors and will transmit the number of boarding and alighting passengers to the on-board computer. These solutions for Automatic Passenger Counting (APC) are in use at many transport operators all over the world. For this passenger counting application iris is using optoelectronic sensors working on various physical principles: Special know-how was accumulated in the areas of thermal infrared sensors (FIR, passive IR), sensors in the near infrared (NIR, active IR), three-dimensional distance measurement using Time-of-flight (TOF) and related signal processing. These various sensor technologies are leading to a portfolio with several product lines, from which – according to the technical and commercial requirements of the project – an appropriate solution for the customer will be chosen. With a strong technological base in micro system technology and an own clean room line iris is able to design and manufacture also the real core element – the infrared receiver – dedicated to the specific requirements of passenger counting in the vehicle. Thus iris is able to optimize the devices already from the receiver element on to the targeted application and has so a special degree of freedom for the design of the sensor solution. The special assembly and test fixtures, created by iris‘ own test engineering, enable a reliable test and calibration for all physical, electronic and optical parameters that are essential for the operation of the sensors. Furthermore enables this consistent computer-based 100% test and documentation of all devices with traceability down to the individual sensor. A special care is taken at the research for new sensor technologies for Automatic Passenger Counting. For this purpose iris is cooperating with various universities and research institutes. This is leading in mid-term to further new generations of APC sensors completing the portfolio offered to the market of public transportation.
